In case you’re not aware, and for any uninitiated that see this comment www.protondb.com/app/1086940 protondb is a fantastic database of Linux compatible games and crowd sourced suggestions on getting the best performance.
Baldurs Gate 3 ran flawless for me, but everyone’s mileage may very depending on computer specs and Linux distro. Proton, and its counter part Proton-GE, work wonderfully the majority of the time. Biggest issue I run into anymore is anti cheat. Which can also be verified by areweanticheatyet.com
For reference, I’m running all AMD with hardware thats a few years old now. Fedora 41 with some tweaks like feralinteractives’ gamemode installed. You can install and use ProtonUp-QT to manage the Proton-GE versions and keep them up to date. I’ve been primarily Linux at home for a couple of years and have not missed windows. I hope more people are encouraged to try Linux and see what it has to offer
