On the store pages, the system requirements lists DirectX11 as another API that can be used with the game. However, this has to be done via the console and it appears that there are some slight visual glitches that only occur when using it. The major glitches I've noticed are that the screen, sometimes including the HUD, will flicker and glitch out. Sometimes without any action, but occasionally when picking up the "fast fire" powerup (I don't actually know what that's called). I haven't noticed these glitches with the Vulkan API, though.

So, the thing I'm curious about is if anyone else uses it or notices similar glitches like the ones I've had.


EDIT: DX11 can be used through command lines and possibly config file changes.

Hi, this is how I fixed the flickering issue:

Maybe this can help you?
