i have linux running for about 1 year on my main pc and laptop. often when buying games i forget to check protondb because most game I play work fine. but i like to play bethesta games, farm sim and older ones also Cyberpunk runns fine on my system. some games may require you to tinker to get them running smooth. and i thankfully never ran into problems with the nvidia drivers for my 2080 super. all in all i would say the linux experiance is quite good overall for my case. as for distro i only have used arch for a longer period but from my tests and what i heared fedora(i tested it on an old laptop worked gread out of the box), PopOs(i tested on my old system (amd fx6300 ,gtx980) ran fine), mint(never tried it myself but people say it’s quite good) and EndeavourOS(same as mint)
