Shaders going nuts after 100 hours

Game worked perfectly for over 100 hours, now it's a slideshow with the shaders going insane. I'm on a pretty beefy rig with a 4090 rtx, so I shouldn't be getting slowdown in a game like this.

I deleted the shader cache folders and set it to High Performance in the graphics settings with no change.

Edit: Swapping from Vulcan to DX12 fixed the issue.
