Hey everyone.
For some reason i got a blue screen when i opened up GZDoom once, and now i just can't open the game anymore with the vulkan renderer. Open GL works just fine though.
I tried different games with Vulkan and they seem to work just fine.

Try delete the zdpc files in %localappdata%\zdoom\cache

If that doesn't fix it, try reinstall your display driver.

Removing the zdpc files worked, thank you!

This is unfortunately the third time this fixed the issue. Either the compatibility check done by the backend is not correct according to the spec (I need to check this), or NVIDIA's driver sometimes build a broken pipeline cache and we need to put in some kind of fallback for this situation.

Looked into this a bit and the driver is responsible for validating its own cache data we saved for it according to the Vulkan 1.3 spec. So basically its the NVIDIA driver shitting itself, but since its been happening for a few people now it may still become our problem.
