I tried, but it fails at compile time and I can't be bothered to try and understand why it doesn't find a stdargs.h that is _clearly_ there. I attempted various solutions I found online for half a day, then just threw the towel and ordered a 25€ replacement from AMD which I'm told has better support than nvidia on linux anyway.

Ah, yeah, that tracks. I've heard the same, though I haven't replaced my nVidia yet.
