It also matters what Linux distro you have. Some of them are horrible. I’m super happy with amd graphics on arch, and have no issues whatsoever, with probably 30 games in steam library that all works very well.
So I think it may be your system and what drivers you installed, or some other config.
I have a 6900 XT card, latest kernel, latest drivers. But I’ve had this graphics card since kernel 5.8 I think, with no issues.
