TL; DR: The last question most players ask is: Is DLSS or FSR "better"? This is an almost impossible question because there are many factors to consider: visual quality, performance, artifacts, support for specific games, etc. Neither technology is the best in all of these categories. But in an area that is perhaps more important - the balance between visual quality and performance - DLSS 2.0 is generally better, although somewhat better depending on the game and the game is significantly different.
We've looked in depth at DLSS several times as it progresses, and recently took a look at FSR, so without going into too much detail about how it works, you should consider that there are two fundamentally different technologies to achieve the same result : Improve performance without significantly reducing image quality. AMD FSR is a simpler technology. It's a space upgrade technology that combines edge detection upgrades with a sharp pass. On the other hand, Nvidia's DLSS is more complex, incorporating temporal data including past frames and motion vectors, and uses an AI grid to help with image reconstruction. Both require game-specific integration, ideally before the final addition of processing and UI effects, and each have different modes in their standard configuration.
There are now many games that support both modes, with a focus on Marvel Avengers and Nekromonda Rifle. The Avengers were created by Crystal Dynamics and used in the Engine House, similar to previous Tomb Raider games they've worked on. Necromunda, meanwhile, is a streaming studio game that takes place in the Warhammer 40K universe and uses the Unreal Engine 4. The FSR integration was a bit surprising for Avengers because it wasn't a title offered by AMD. Both titles use the first iteration of FSR, which AMD calls FSR 1.0, and they make it clear in their documentation that people like to use the "FSR 1.0" brand in their games. Meanwhile, both of these titles use DLSS 2.0.
This is a working test of both components and image quality components, so check out the video above for everyone. We're more interested in DLSS and FSR patterns working the same way, rather than comparing both with the same display resolution, which is not very suitable for real-world use outside of "for science" research. p>
