I’ve never had an AMD card. I don’t intentionally avoid them or have anything bad to say about them, my systems have just always included Nvidia cards.

I’m assuming you’re talking about native Linux games?

If so, KPatience. lol

I’ve used Fedora Silverblue. I wouldn’t recommend gaming without the proprietary Nvidia drivers. If you’re okay turning off Secure Boot, installing Nvidia drivers isn’t too bad depending on what card you’re using. Fedora doesn’t support Nvidia drivers so it can be a headache in some circumstances. If you want to use Secure Boot, tweaks are required to install the Nvidia proprietary drivers. RPM Fusion offers some help : https://rpmfusion.org/Howto/NVIDIA

Vanilla OS installs the Nvidia drivers out of the box even with secure boot enabled. They’re currently switching between an Ubuntu base to a Debian base so I don’t know how that will change things. The current version is pretty good though. https://vanillaos.org/

Do they come in colors other than white?

If you enjoy ambient space music, No Man’s Sky is wonderful.
