Originally the 545 drivers currently on Unstable were the one provided in the previous Testing update, then they rolled back to 535, then in this update nothing changed apparently. I can’t pinpoint what is broken I can run games, just that I have horrible performance in them. Current Unstable state is the same to me it is broken. With my snapshot on 535.113 drivers I’m good, if I update to current Testing I’m good for poor performance with 535.129 It is like I have a problem with shaders and everything appearing on screen it drops FPS to huge dips.
I did many “cleaning” to try to troubleshoot the origin of issue, I regenerated my Proton prefixes, I cleared Steam shader cache, force redownloading, and recompiling them on each drivers I tested on Testing and Unstable, and only with my previous snapshot I’m good.
