Got my brother to use Linux as their daily driver. We upgraded his 10-year-old computer to the modern age and wiped his windows installation and put on Bazzite instead. He says all the games he’s tried along with bunch of other tools/alternatives he uses just works. Just had some issues with F1 and F2 keys when playing StarCraft II, but he easily looked up a solution online.
Linux gaming and desktop experience has come a long way.
