I recently updated my computer from i5 4690 / GTX 970, to Ryzen 3700x / 5700xt, because I’m sick of how bad Nvidia Drivers are. 3 times I’ve had my linux install completely destroyed by updating Nvidia Drivers. Everyone says amd is better for linux support so I figured I’m going all amd and if I summon up the courage to move back to linux at home I hopefully won’t end up with a dead install.

The AMDGPU driver is open-source and generally seem the best integrated with the rest of Linux; performance is comparable to Windows. The nVidia closed-source drivers also give performance comparable to Windows but have issues like graphics corruption with KDE on suspend (https://bugs.kde.org/show_bug.cgi?id=364766, supposedly KDE's misuse of OpenGL). The open-source Nouveau drivers for nVidia are not really usable: the team has to reverse engineer everything and nVidia doesn't really support their efforts so it's rolling a stone up a hill.

Intel graphics are open source but they're mostly used on laptops, so I don't think the drivers support much beyond basic functions. I guess light games would probably work well with them though.

The Intel drivers on Linux are fine, they are very reliable and don't lack important functionality. The problem with Intel graphics for gaming is underpowered hardware.

I was looking at https://wiki.archlinux.org/index.php/Intel_Graphics. There are quite a lot of workarounds listed which have the effect of disabling certain hardware optimizations. I'm sure the drivers work well for most people, since even the Nvidia drivers are quite usable, but they do seem to have some bugs.

NVIDIA drivers are not as bad as they used to be, but it's a proprietary driver so you're dependent on NVIDIA, who doesn't care that much about Linux gamers (probably 0.1% of their bottom line).

I have a NVIDIA card I bought because I did not know better (and I used to run Windows). I'm lucky that it works fine on Ubuntu 18.04 (I can play games like the 2016 Doom fine) but if I had a choice I'd pick an AMD GPU.
