was this same drivers or before after update?Could be - So far COD AW, SW Fallen Order and a couple of other games are working fine - smooth 60+ FPS. All recent games.
Doom Eternal, RDR2 and CP2077 are suddenly running like crap as of today...
Unless the DX12/Vulkan API is accessing some portion of the GPU that's now borked (highly unlikely), I'm leaning toward a driver corruption, or perhaps even a power supply issue (not enough power)... but I'm open to suggestions. It's very strange.
EDIT: sorry for the quasi double post. The previous one didn't show up when I refreshed.
