I’ve been experiencing a recurring issue where my FPS suddenly drops to a very low value (capped around 10–30 FPS). It seems to happen randomly, though I’ve noticed it occurs more frequently after alt-tabbing. Interestingly, alt-tabbing doesn’t always trigger the problem, but it happens often enough to be frustrating.
A temporary fix I found is to change the anti-aliasing settings, which restores the normal framerate. However, the problem eventually comes back, forcing me to adjust the anti-aliasing again.
This issue only occurs when using Direct3D 12. Switching to Direct3D 11 completely resolves the problem, but I’d prefer to use DX12 if possible.
Has anyone else encountered this issue?
