Thank you, I know now.
I find it quite ridiculous that after 6 years of early access, not even AMD graphics cards are properly supported.
Maybe it will work when the game is finished in 2035. (And you pay so much money for something like that)
AMD cards were supported for a long time, but after AMD's patch 22.5.1 something was messed up and because there's already a solution on the way (DirectX instead OpenGL, by going Unity), there was no need for a quick hotfix. So no, it's not been 6 years...
