Steamdeck here and the last time i played on Windows was like 2015/2016 but never again after Win10 shutdown my System for an Update while i played a LoL ranked Game.. That was the last Time i used Windows for privat use. After that i formated the HDD and installed Linux Mint
I'm still very happy with this decision
Yes, but at least the kernel Anti Cheat belongs since 2024 i belive? There was a long Time before DXVK or Proton you can play nearly nothing on Linux but LoL worked "okayish". Nothing close to play ranked but for a casual normal game it was good enought to let me switch to Linux this times and ditch Windows at all
