AMD's FSR three technology made a surprise debut earlier this month in two games: Forspoken and Immortals of Aveum, and we're geared up to present you an early appearance of the technology. There's plenty to cover in this article together with a discussion about frame pacing, photo fine and latency.
FidelityFX Super Resolution 3 (FSR three, for short) is AMD's solution to Nvidia's DLSS three, which introduced frame generation support for RTX forty series portraits cards about a yr in the past. The overarching concept is that among every typically rendered frame, frame technology can create an interpolated body to improve the smoothness of the game's presentation.
FSR 3 introduces body generation it truly is similar to DLSS 3 in its functionality and desires, with AMD beginning to roll out their take on the technology now after announcing it on November 2022.
The principal distinction among FSR three body technology and DLSS three body generation at a floor degree is compatibility. DLSS 3 is distinctive to Nvidia's RTX forty pictures cards, with Nvidia claiming that simplest their Ada Lovelace structure has the optical glide accelerator performance essential to power frame generation.
FSR three, on the other hand, is to be had for all pics cards, with reliable guide for AMD's Radeon 5000 collection and Nvidia's RTX 20 collection and above. AMD is correctly claiming that they've an optical float frame interpolation device this is performant enough to no longer require unique hardware accelerators, which clearly disrupts the GPU features race – supplied it sincerely works well.

With approximately a 12 months hole between the launch of the 2 technology, currently there may be most effective two video games with FSR three body generation help, Forspoken and Immortals of Aveum. Enabling the characteristic is as easy as turning on FSR 3 upscaling after which toggling body era in the sport's settings.
A slide from AMD's presentation on FSR 3 and Temporal Upscaling
Unlike with DLSS, FSR 3 frame technology requires the use of FSR three upscaling, so that you are tied to FSR if you want to get admission to AMD's body gen tech and it cannot be enabled with local rendering or DLSS upscaling.
FSR three also introduces a new local AA mode that applies the temporal anti-aliasing and sharpening thing of FSR without upscaling for the ones looking for better picture pleasant than what FSR generally offers.
While FSR three's game integration is as easy as a toggle, unfortunately it's not a era that "just works." And that is in which we need to begin speakme about FSR 3's body pacing and configuration.
FSR three works otherwise relying on whether you're the use of variable refresh price (VRR) era or no longer. It also works in another way relying on whether or not you're gaming with VSync on or off. The genuine configuration you are the use of substantially alters the final FSR three output quality and the manner it paces frames in your show. Let's smash it all down.
Right now, all VSync off configurations in Forspoken and Immortals of Aveum are basically damaged with FSR three. Frames are not being paced effectively with VSync disabled, leading to either a blurry or juddery presentation (or some combination of each issues).
This means that during a VSync off kingdom, FSR three presents 0 advantage. While it does growth the body rate number you may see in an FPS counter, the real visible presentation is no one of a kind from using FSR 3 off, and in a few instances may be worse.
For a better representation of photograph pleasant comparisons, check out the HUB video under:
In the video above is an example of ways VSync off with FSR 3 frame era is pacing frames to the show. You'll ought to excuse the low quality slow motion pictures right here, we don't have a specifically notable one thousand FPS camera.
Both configurations are strolling at approximately a hundred FPS with VSync off on a variable refresh price display. However we don't seem to be getting a real 100 FPS output with frame technology enabled; alternatively, relative to natively rendered 100 FPS, body era seems to be outputting frames at a far lower rate. We consider with VSync off that FSR three isn't always properly pacing or showing half of the frames to the factor where it makes little to no distinction compared to no longer the use of frame technology and clearly playing at a decrease frame fee.
AMD tells us that VSync off in both launch titles is using an older method for managing body technology, older than the model described on their GPUOpen website. We have no idea why an vintage version of FSR three might be used to release the era if a repair for VSync off is thought and implemented in more recent code, however here we are.
FSR 3 body technology additionally would not paintings well with any variable refresh fee configuration while gaming internal your monitor's refresh rate variety. Normally when gaming with VRR enabled, your frame price and display's refresh fee are synced to lessen judder and display screen tearing from any mismatch. FSR three breaks this functionality.
When we view sluggish movement photos we are able to affirm this is the case. Without body technology, a a hundred FPS output is continually paced to the display. With frame era enabled, the reveal's refresh price counter stays broadly speaking at its most (in this example 160Hz) with the occasional dip to a decrease refresh charge, so the one hundred FPS output isn't always synchronized with the refresh fee. This causes frame pacing judder, and as some frames are being proven on display screen for longer than in a VRR state, it may also cause increased blur in some situations.
However, while we evaluate this to DLSS 3, we will see that Nvidia's body technology generation is efficiently and as it should be pacing frames and operating just satisfactory with variable refresh rates, as you'll count on for a 100 FPS output on a 160Hz monitor. This is actual for FSR 3 whether you've got an Nvidia or AMD GPU.
This is likewise genuine in case you use a body cap inside your screen's maximum refresh fee. Native rendering with a 120 FPS cap will transfer your VRR succesful display to run at 120Hz. With FSR three body technology, capping to one hundred twenty FPS will nevertheless make your display run at the most refresh price, in this example 160Hz, which is a mismatch that causes judder – despite the fact that the frame time output graph seems smoother. The simplest time we saw correct frame pacing turned into while body era was capable of max out the display's refresh rate.
In practice this limits the gain of FSR three. The larger the distance in output frame price and reveal refresh fee, the greater juddery and unsightly the FSR 3 enjoy is. While this does work better than VSync off and the actual variety of introduced frames is higher than no longer using frame generation, relying on how low the body charge is, FSR three can simply sense much less smooth, which defeats the entire motive of the generation.
These troubles are minimized at better frame prices and a better gap for your reveal's max refresh price. In our configuration, for instance, whatever above a hundred thirty FPS on my one hundred sixty Hz reveal felt quite desirable and looked clearer than now not the usage of body era and therefore playing at a lower frame charge. The perfect experience happens when jogging at the max refresh charge, however just a little below that still labored properly.
We observed a small improvement when disabling variable refresh costs and strolling at a set refresh with VSync on. My screen's refresh charge have become much less erratic, which helped pace frames a little better, but in the end if you are jogging FSR 3 underneath your screen's max refresh rate on this state, there is nonetheless a risk of judder as we recognise is the case for constant refresh gaming. The identical applies as defined before, where anything above one hundred thirty FPS on my 160Hz monitor felt pretty precise, but under that and specifically underneath one hundred FPS the judder become very sizeable and not ideal.
With the sort of sturdy awareness on VSync on gaming and maxing out your refresh price, we accept as true with AMD hasn't tested variable refresh fee configurations effectively sufficient, and hasn't optimized the enjoy for what we would say is the maximum common and applicable configuration that consist of variable refresh price.
In response, AMD tells us that FSR 3 became designed to be used with VSync on with the goal of maxing out your reveal's refresh charge. They also advised us they had frame pacing operating successfully with variable refresh fees in their labs, something we have been not able to duplicate on both Nvidia or AMD GPUs. My experience seems to align with different human beings checking out FSR 3 frame era.
With such a strong focus on VSync on gaming and maxing out your refresh charge, we consider AMD hasn't tested variable refresh rate configurations properly sufficient, and hasn't optimized the experience for what we would say is the most not unusual and ideal configuration that consists of variable refresh fee.
Pretty much each gaming reveal bought within the final five-7 years helps it, so having to disable VRR or track settings to max out your monitor's refresh rate appears like an old college method in a world with good sized variable refresh, once in a while with very high max refreshes like 240Hz or even 540 Hz these days.
At this factor it becomes apparent that FSR 3 would not run in addition to DLSS 3 in its contemporary country as the latter does assist variable refresh rates, VSync on, and VSync off. With DLSS three body generation, you can use any configuration you want, turn on the body technology toggle and enjoy properly paced interpolated frames.
For a higher representation of photo quality comparisons, check out the HUB video under:
With FSR 3 frame generation you need to make certain your output frame price is excessive sufficient, in all likelihood disable variable refresh charges, and make sure VSync is on. That's an excessive amount of fiddling around while the direct alternative and competitor technology correctly "just works."
Now permit's speak about the real best of FSR 3 body technology when utilized in a great configuration: maxing out your display's refresh price. The fine of interpolated / generated frames is probably the largest electricity of FSR 3 proper now and one thing that AMD have largely gotten right.
The largest win for FSR 3 frame era is how FSR handles UI factors. DLSS three struggles with this, and even as it has stepped forward due to the fact release, there are still titles that do not have ideal coping with of UI elements, frequently presenting garbled, distracting, awful UI in movement. This became by means of a ways the maximum substantial trouble from Nvidia's body technology. With FSR 3, we didn't spot any UI issues testing Forspoken or Immortals of Aveum. Both games with FSR 3 frame generation take care of the UI perfectly, no garbling, no distracting issues, which removes the largest artifact seen from this technology.
For a better representation of picture satisfactory comparisons, test out the HUB video beneath:
Even in a identify like Immortals of Aveum which commonly has right UI rendering from each FSR 3 and DLSS 3, FSR 3 has the brink. When we observe semi-obvious UI elements, for instance, FSR three higher handles interpolation in the back of the transparency in movement as compared to DLSS three. This is due to the fact FSR 3 has a method for sport developers that fully decouples the UI loop from the body generation loop. We suspect this is how most video games will take care of the UI with FSR three, despite the fact that AMD did point out there's an option sport developers can use to put the UI thru the interpolation bypass, some thing I hope isn't used if it creates great artifacting.
Like with DLSS three, it's hard to identify any artifacts from the FSR 3 generated frames themselves whilst the very last output frame fee is in the one hundred to one hundred twenty FPS variety or better – which normally corresponds to a native 60 FPS render charge or higher. While the troubles are glaring when slowing down the footage and inspecting frame by way of body, having these lower great frames interspersed with higher exceptional frames considerably reduces their visibility and the way major those artifacts are. The better the frame price, the shorter each of these frames is being proven.
And quite a lot identically to DLSS three, FSR 3 frame era falls apart while used at a low native render price, specifically whilst taking 30-forty FPS and turning it into 60-70 FPS. This is not a encouraged use case for frame generation, it simply does not work well, artifacts in motion are pretty noticeable and this considerably reduces visual fine. Having a relatively excessive output frame price is prime to ensuring all frame era tech works well.
Having a fairly excessive output body charge is key to ensuring all frame era tech works properly.
When extra intently assessing the high-quality of FSR three generated frames, we'd say their best is not quite as suitable as DLSS three generated frames, even though in practice at a high sufficient body charge it is tough to tell the difference.
For a better representation of photo first-rate comparisons, test out the HUB video below:
Typical pain points for body generation are any excellent details, like wires or chains. When slowed down (as proven in the video) you'll see that each 2d frame has garbled chain detail for both DLSS and FSR body generation, despite the fact that DLSS ends up much less garbled. Transparency consequences ride up frame era, with FSR three again searching a piece blurrier in its generated frames for this magical white effect.
Fast complex movement can purpose interpolation troubles as properly. When changing your weapon in Aveum, each DLSS three and FSR three produce a whole lot of garbling as every body struggles to deal with the speedy modifications in movement. However on near inspection the level of garbling is extra on the FSR 3 side, though neither tech can be defined as producing high exceptional frames in this case.
In many different situations you'll see comparable output from DLSS 3 and FSR 3 body era, at least based on the cutting-edge pattern of 1 that we've. For instance, easy movement like digital camera pans or translation usually works well, with both technology relying on motion vectors to supply the equal stage of element as in 'actual' frames. More complicated textures and factors like foliage can have issues at some point of simple movement, but we did not see a clear winner for this among DLSS and FSR. We suspect like quite a few other implementations of DLSS and FSR, that those pleasant battles will vary from game to recreation.
While artifacts may be tough to spot with a high sufficient frame fee, it is quite clear throughout each FSR three games that generated frames are not equal to commonly rendered frames in pleasant. Using either DLSS or FSR with out frame generation ensures the least quantity of artifacting, however with frame era on, it's uncommon to get the "perfect" generated body. When permitting FSR 3 you'll ought to accept that the ensuing image exceptional from each body is decreased to improve the smoothness of the presentation, with a decrease pleasant output in comparison to rendering the sport natively on the same frame fee.
But the largest trouble with FSR 3 picture satisfactory isn't always the generated frames themselves, it's the excellent of FSR upscaling, which AMD tells us has best received minor improvements (if any) relative to FSR 2.2.
This means that during a battle among FSR 3 and DLSS 3 frame generation, DLSS normally has exceptionally advanced picture exceptional – and that is right down to DLSS having better upscaled image first-rate, to be able to dictate the first-class of the "real" frames that are shown and input into the interpolation algorithm. So whilst the difference in generated body satisfactory is not all that substantive at a high body price, the overall difference in photo first-class from upscaling in reality is.
For a better illustration of image first-class comparisons, test out the HUB video below:
Even at a 4K decision, which we used for all photo nice comparisons in the films, in each Forspoken and Immortals of Aveum, DLSS upscaling is advanced to FSR upscaling and that influences the visible presentation for body era. In specific, DLSS has greater photograph balance and much less shimmering, in addition to every so often better first-class element reconstruction in movement.
Even whilst pitting DLSS Quality mode up towards FSR Native AA upscaling, DLSS Quality was better in both titles evaluated, it truely has higher picture balance in motion that is significant as each video games are heavy on foliage and particle consequences. While we did not significantly test this, we assume the distance to widen as it typically does while checking out decrease render resolutions or decrease output resolutions.
This ends up as the defining distinction in picture best among the 2 techniques. As FSR three body era requires the use of FSR upscaling, you are locked into using that upscaling even supposing a higher exceptional era is available. In a head to head war with DLSS three body era the usage of DLSS upscaling, FSR 3 has lower usual picture best due to this despite the fact that we were k with the quality of FSR 3 generated frames. Until AMD can enhance the best in their upscaling component, this hole among AMD and Nvidia tech will continue to be.
For a higher illustration of picture high-quality comparisons, test out the HUB video below:
The pressured use of FSR upscaling with FSR 3 frame generation also locks out probably superior combos. For instance, Nvidia RTX 30 series proprietors would have a higher enjoy the usage of DLSS upscaling with FSR body generation, as they can't access DLSS frame technology however can use DLSS upscaling.
We consider AMD doesn't need to provide Nvidia owners the exceptional revel in with FSR frame technology, hence the reason for locking it to FSR upscaling for feature parity throughout Radeon and GeForce GPUs. But this does emerge as hurting Radeon proprietors, too, due to the fact a sport like Forspoken appears higher with local TAA than the use of FSR upscaling or maybe the FSR Native AA mode. Having get right of entry to to native rendering frame technology, or DLSS FSR frame generation, or maybe XeSS FSR 3, would be ideal.
Finally, permit's talk about latency and FPS output performance. On a Radeon RX 7900 XTX, FSR 3 is pretty effective at increasing the output FPS. When the use of the Native AA mode within the scene we examined in Immortals of Aveum, we went from forty three FPS to seventy nine FPS, an 83% growth.
At the equal time, latency decreased due to AMD's integrated latency decreasing tech that is carried out while body generation is enabled. So with FSR 3 on, we ended up seeing a 23ms drop to latency, noting that the muzzle flash we have been checking out in Aveum isn't instant on mouse click on for this reason the high overall numbers.
Using Quality upscaling rather, we saw frame generation increase FPS from 71 to 122, a 72 percent boom. Latency on this configuration dropped through 8ms. However the lowest latency mode right here become still rendering at a higher local frame fee, FSR with Performance mode upscaling delivered ninety one FPS – lower than FSR three Quality with body era – but it had around 10ms much less latency.
One interesting discovery is that for like minded Radeon GPUs, currently Anti-Lag does not effect latency to any tremendous degree with FSR 3 enabled. While Anti-Lag does have a large effect for non body gen configurations, slicing FSR Quality mode latency by using 33ms on the same frame price, this does not practice to border technology. AMD confirmed those findings, noting that right now Anti-Lag is useless inside the FSR three release titles and the driver-aspect characteristic and its corresponding profiles for these video games needs extra paintings to well discover FSR 3 body technology output.
On a GeForce RTX 4090, there has been no latency improvement between frame era on or off. When using FSR three Quality we noticed round 105ms of latency at eighty four FPS within the scene examined, and with frame generation that improved to a hundred and forty FPS with 108ms of latency. The RTX 4090 didn't benefit quite as a lot from FSR 3 frame technology as the Radeon 7900 XTX did, although the margins among them in terms of percentage uplift were not big.
A lot of AMD's advertising has focused on FSR 3 supplying each a better body rate and lower latency than local rendering, which might be the equal claims that Nvidia makes for DLSS 3 frame technology. However, what we've got visible is that almost all of this latency advantage is from additionally applying upscaling, not from the frame generation thing itself which does not enhance latency to the identical diploma as running at a higher native render fee. We consequently come to be with the equal scenario as DLSS frame era, wherein it does enhance the smoothness of the presentation, but would not sense as responsive as true higher frame charge gaming.
The actual kicker for FSR three latency is that Nvidia's modern DLSS three implementation grants substantially decrease latency because of its complete integration with Reflex. On a GeForce RTX 4090, Reflex provides a strong latency development: when the use of DLSS Quality upscaling and no body technology, Reflex itself reduces latency from 106 to 87ms. This is a similar benefit we saw from Anti-Lag on the Radeon side, in which we went from 122 to 89ms of latency below comparable situations.
But as Reflex works and is continually enabled with DLSS three body technology, in our testing we saw an output body rate of one hundred twenty five FPS for 90ms of latency the usage of Quality upscaling. FSR three, without Reflex, delivered a hundred and forty FPS for 108ms of latency. So even as FSR body era become able to growth the body price by 67%, versus just a 42% growth for DLSS body era, DLSS ended up with 18ms lower latency.
This is where the lack of compatibility for FSR 3 with Anti-Lag hurts. The RTX 4090 the use of Nvidia frame era tech and Reflex brought one hundred twenty five FPS and 90ms of latency. The RX 7900 XTX the usage of AMD body technology tech and Anti-Lag introduced 124 FPS with 107ms of latency. In a first-class vs. Exceptional evaluation that gives Nvidia the latency aspect, till AMD can get Anti-Lag working successfully. And given that you could use Reflex on an Nvidia GPU along FSR 3, presently the lowest latency reports with FSR 3 era may be on an Nvidia GPU where that tech is integrated.
It's now not all awful information although. These performance figures do advise that the optical go with the flow pass in FSR 3 has less overhead than the optical go with the flow skip in DLSS three, that means that FSR three promises a better FPS increase from the same base body fee. But until latency is equalized this doesn't result in a better experience from FSR – and won't till upscaling photograph nice is improved both.
Overall, we aren't impressed with what we've got visible from AMD's FSR three to date. The characteristic appears rushed, incomplete, and not fully geared up for top time. There are too many incompatibilities and configuration issues, which stand out badly in comparison to Nvidia's DLSS 3, itself a function with issues. The resulting FSR 3 body era revel in is tough to suggest outside a few area of interest use instances.
The same kind of caveats that we pointed out with DLSS 3 also observe to FSR 3: to avoid seen artifacts in generated frames, you may need a base frame charge of at least 60 FPS with a very last output round a hundred to a hundred and twenty FPS. And for the reason that frame era does now not improve latency, for that authentic excessive refresh price revel in, you may want a base frame fee of a hundred to one hundred twenty FPS (with a final output above 200 FPS) for the responsiveness we normally associate with the quality gaming experiences.
This is why we refer to frame technology as a function that enhances the game's smoothness, in preference to some thing that improves overall overall performance – the blessings are entirely visible in nature.
To be completely clear:
FSR 3 isn't any better than DLSS three at any of these elements that, proper now, are fundamental to border era. Where AMD stumbles is they've taken a characteristic that already has rather limited usability and restricted it in addition. Not only do you presently want to fear about base body fee, but you will also need to ensure you've installation VSync correctly and are pumping out sufficient frames to avoid judder.
This is why we refer to frame era as a characteristic that complements the sport's smoothness, in place of some thing that improves universal performance – the advantages are absolutely visible in nature.
You'll need to be happy with sacrificing proper variable refresh price functionality – a feature we strongly advocate each gamer uses – to get admission to frame technology. There are situations in which that change off alone is not worth it, as FSR three may be less easy than no longer the use of it, defeating the entire reason of a technology designed to enhance smoothness.
That's now not to say FSR 3 in no way works properly.
If you have a reasonably excessive output body charge, and are jogging at or near your reveal's most refresh fee with VSync on, the FSR three body generation enjoy can be smoother and better than no longer the usage of frame generation. But when we have DLSS three frame technology that – to use an Nvidia-ism "just works" with capabilities like VRR – going backwards on compatibility with FSR 3 in reality stands proud.
AMD has definitely positioned numerous paintings into making sure the body technology a part of the technology works well, with speedy and effective interpolation. It has decrease overhead than DLSS three body generation, it has 0 troubles rendering UI that we have seen thus far, the overall first-class of interpolated frames is acceptable, and it works throughout all pictures playing cards – no unique hardware required. That's a win for FSR three, and it is the most outstanding thing of what AMD has produced and does provide a strong basis for improvement.
But all that extremely good work it is been placed into generating frames is permit down by AMD's inferior upscaling technology, that you are locked into the use of with FSR three frame era. The usual image great – factoring in generated frames and normal frames – is actually higher from DLSS 3 and that is largely right down to Nvidia's upscaler. Without vast development to FSR upscaling, specifically at lower resolutions, DLSS three will maintain to offer a higher ordinary package deal than FSR 3.
FSR 3 is likewise let down at the latency the front with its incompatibility with Anti-Lag for the time being, meaning that DLSS 3 on an Nvidia GPU gives you lower latency at the identical output frame price than FSR 3 on an AMD GPU. The gulf widens for Radeon RX 6000 collection which can not even use Anti-Lag at all, and owners of older Nvidia GPUs will be praying for Reflex in FSR three titles as the built-in latency decreasing tech in FSR 3 isn't overly effective.
AMD says that a number of these problems might be progressed. They're running on Anti-Lag compatibility, VSync off has been constant in a more recent version of FSR 3, and they may be aware about VRR compatibility problems. But a number of those have to have been resolved before launch, so that everyone that turns it on is treated to a extraordinary experience. Instead, plainly AMD rushed this out to make a September release cut-off date, alleviating pressure that become put on themselves via announcing FSR 3 a ways too early.
We can best examine FSR 3 on what is in front of us right now, which is integration into games with masses of problems. If you may use FSR 3 to max out your reveal, we suppose the enjoy could be quite exact for you and we might likely recommend giving it a try. If that is not feasible, it is difficult to justify using right now.
And this is certainly the prevailing nation of FSR three. It isn't overly competitive with DLSS 3, and it would not do a lot to shut the function gap between AMD and Nvidia, despite the fact that we forget about the big difference inside the range of supported titles. If AMD can allocate sources to improve FSR three, it must be feasible to get it to that stage we want although. Solve the body pacing and VRR compatibility troubles, get it working with Anti-Lag and – possibly the most hard of all – enhance the pleasant of FSR upscaling and FSR 3 will be the gold widespread for frame technology era given its low overhead and extensive compatibility.
