Should add eduke32 (that’s the repo, site here) for Duke Nukem 3D, believe Ion Fury (which is phenomenal) is built on that, think I’ve seen mention of it working with other build engine games, I’ve used with assets from world tour, it’s a better experience imo.
Gzdoom has some great games built on the engine too (bit of a tangent), Selaco and Hedon both fantastic games.
That’s super bizarre and sorry you’re having those issues. I have a 4070ti w/ an 11900k on arch (use debian on my laptop and printers, chose arch for more recent releases for drivers in particular) and guess I’ve been lucky, arch wiki won’t 100% help but might point you at other possible configs?
Had solid luck with the nvidia-open drivers, and really other than setting a few flags for hdr in KDE (which I’m not sure it’s still needed), I do recall looking at DRM kernel mode settings (section 1.2), most of my grief though has been HDR related (and gamescope doesn’t play nice with some games, steam big picture also can render strange on higher resolutions)
