I will say Proton is really great these days, and I get excellent performance in the games I care about. But personally, I would wait to try until they work out some problems with the new UI.
- The new steam overlay currently has problems on OpenGL games and will crash if you open it.
- Under Xorg, can’t select items from any steam drop down menu (game properties, etc). Works if you enter Big Picture mode though.
Someone reported the overlay problem back in the UI beta and Valve just… ignored it and proceeded with launch. It’s been 3 weeks and I still can’t use the overlay in my main game (Hunt Showdown) because of this. Pretty shocking tbh, I’ve never had a steam stability issue of this magnitude that wasn’t fixed within a day.
Your wifi issues sound like a network card with poor support in the kernel. I think hardware compatibility is one of the most understated sources of user friction in Linux. Nearly anything modern will work but only a few vendors’ network drivers are really as performant as their windows implementation.
Not much you can do as a user unless you want to become a driver developer and/or reverse engineer.
