since my new setup I can´t set r_usethreadedrenderer to 2 without problems. It makes the world (e.g. trees) glitchy and is actually unplayable. r_usethreadedrenderer 1 and r_usethreadedrenderer 0 works fine.
Using Wine it does work fine.
I´ve made a small video. In real it is way more noticable… but it should be visible on the video too.
It would be interesting to see if it also happens on Quake 4 or other idtech4 Game.
I think it may has to do with Zen2 (3700X). Solarisk got (nearly) the same GPU as me and he said it works without problems for him.
Any idea? Where should I open a bug report? Or does someone even have a good fix?
