I'm curious if that fixes the issue I was facing. FSR2 (and 1 for that matter) basically did nothing for performance, or even reduces it when enabled. FSR3 on the other hand often gives me like up to 40 additional FPS in some games, but of course not all games have FSR3.
I still see the same old issue of a lot of Proton games degrading in FPS when you change graphic settings though, requiring a restart of the game to properly test and optimize them. No idea if that's an AMD or Proton specific issue though.
Eh, FSR3 upscaling and FSR3 frame generation are different things. I'm personally a fan of upscaling, it's great for a sharper picture on my large 4k TV (I use a living room gaming PC), but not at all a fan of frame generation, as it introduces more input lag for the illusion of more frames. Not a tradeoff I'm ever willing to make when VRR already does an incredible job of creating the illusion (and a degree of reality) of good performance when my framerate drops.
If Valve's Employee Handbook is to be believed, they don't use a formal project structure with static teams. Instead, each developer works on whatever project interests them, and one of Valve's current goals is to improve game performance on Linux/AMD by contributing to upstream open source projects.
Valve is as close as we've gotten to someone paying a bunch of industry veterans to contribute to open source. It's amazing what happens when all innovation isn't black-boxed in an internal repository and forgotten about.
