Will it be possible to create a drop-in DLSS replacement that works across a range of games ('dlss2fsr', as suggested by a Github user) or do you see it being more of a series of mods each tailored to a given game?
PotatoOfDoom: Only with a few compromises. It would be possible to create some kind of mod that gets the FoV and Depth values from a simple ini file. This mod could work for almost any DLSS game, but the image quality might not be as good as it could be. I mean even Nvidia optimizes DLSS for certain games. For example, the first versions of DLSS had terrible ghosting in Cyberpunk, while later updates to DLSS improved the situation. I can't speak for other games, but for example Cyberpunk unintentionally sends the object ID buffer to DLSS (which is a buffer that assigns a single color value to each object in the scene). DLSS doesn't need this buffer and can't do anything with this information, but this allows me to improve anti-ghosting (especially when driving) tremendously. Also, the ComputeRootSignature bug I mentioned earlier is unique to Cyberpunk and makes this version of the FSR mod incompatible with any other game. Every single game has some unique quirks or even bugs that make it important to optimize each game to get the best experience. I obviously can't do something like this for every single game, but I think if there is some kind of DLSS2FSR framework, it should be possible for other developers with some programming experience to easily integrate and optimize FSR for other DLSS games.
