Unfortunately the biggest issue now is the anticheats that only function on windows. My friends refuse to switch to Linux because you cannot play:
- fortnite
- league of legends
- escape from tarkov
- battlefield
- apex legends
- valorant
- R6 siege
- GTA 5
- Rust
- Destiny 2 Etc
They'll play other games but because they mainline one of these they refuse to leave. As long as SteamOS has no answer to these anti cheats windows will maintain a dominance.
