Graphics Card Crashing?

[[Unknown]]

Crashing after use without bad temps or load could mean you have bad VRAM. It's not common, but it does happen. I don't know of a memory test tool for VRAM, but it seems likely one would exist.

For FFT, I'd try reducing settings and see if it still happens. It might mean running out of some resource on the GPU and restarting the driver.

In both cases, I'd try turning off texture scaling and use 1x PSP for a while. See if it reproduces. Additionally, try other backends like Vulkan or Direct3D 11. I would also definitely recommend checking for graphics driver updates.
