For decades, Microsoft controlled PC gaming. If you wanted to play, you used Windows. It wasn't just the dominant operating system, it was the platform that ...
Since you covered AMD and not Nvidia: pre 1650 cards are completely unsupported (some distros keep old drivers in their repos, for how long - nobody knows), RTX20xx is like a corncob up your ass on Linux, RTX30xx and above start to handle things better, with RTX30xx losing up to 20% of performance and 50xx about 5-10%, in extreme cases (iirc The Last of Us) you will be lucky to break 20 FPS. There’s no Nvidia App, no Broadcast App either. There are currently a few versions of drivers, open source (not made by Nvidia), half open (made by Nvidia) and fully closed source (made by Nvidia), which only adds to the annoyance, as some drivers might work better for certain games, but obliterate performance in others, not to mention random crashing issues.

Haven’t touched NVIDIA since 900 series for basically this reason. NVIDIA drivers are pure garbage and their GPUs are beyond overpriced for gaming.
