TL; DR: Nvidia DLSS comes in several versions ranging from 1.0.0 to 2.2.10. Regardless, game developers can update it, but it will take some time. However, DLSS client libraries are available so that users can update their DLSS, but only in the original version (for example, DLSS 1.0 can be upgraded to 2.0).
There appears to be a new version of Nvidia's upgrade technology for every new wave of games that DLSS receives. For example, Doom Eternal DLSS 2.1.66 and Rainbow Six Siege have version 2.2.6, Unreal Engine 5 comes with DLSS 2.2.9, but they all need to upgrade to the latest DLSS version...maybe version 2.2 .10 found in Rust.
Users can wait for the developers to update the DLSS on future game patches, but a manual version is also possible. This was discovered by users who replaced related DLLs with DLSS libraries in game installation folders, which could allow for newer features, image quality, or performance improvements. To replace the files, you need to buy "nvngx_dlss.dll" for the version you want and replace it in the game installation folder. A quick Google search will result in these dll files, but it's hard to determine which ones are safe to download.
To help with this, TechPowerUp has created a library of DLSS files so users can download the version they want with peace of mind. We trust TPU, which says all files are "checked manually so the original version is not modified".
Contains The library currently contains 23 files, 18 of which are DLSS 2.0 files and the other 5 are DLSS 1.0 files. The file range is from DLSS 1.0.0 to 2.2.10. TechPowerUp expects the file library to grow with the release of new versions.
Note that DLSS 1.0 games cannot be upgraded to DLSS 2.0 by replacing the file. Only the game developer can create the full version of Remedy Entertainment in Control.
In theory, each new version should be the same or better than the previous version in terms of performance and image quality, but some user reports indicate otherwise. Depending on the game and the DLSS version, the results will vary, so if you are modifying and optimizing files, you should try them all until you find the best game. p>
