@beardalaxy @BlinkRape That error message basically means the GPU driver crashed gracefully (instead of locking up the PC the game quit). I rarely get this with Vulkan in games that give both DX11 and Vulkan options (so I just go with DX11 and deem it as a game bug). Never on DX11 games though.

I would try without any OC or undervolt (run GPU with default settings). It could be the settings aren't stable anymore and need to be toned down some.

If the GPU keeps crashing when stressing the PC it could also be power unit related. That's how I found out my last PSU was going bad. I would suspect RAM last to be honest. Usually if those fail they fail noticeably and BIOS should shut them off before booting (modern motherboards have pretty good tests on boot for RAM sticks).

Just read you fixed it with some registry magic, but posting this anyway just in case.
