Even gamers nexus’ Steve today said that they’re about to start doing Linux games performance testing soon. It’s happening, y’all, the year of the Linux desktop is upon us. ᕕ(ᐛ)ᕗ
Edit: just wanted to clarify that Steve from GN didn’t precisely say they’re starting to test soon, he said they will start WHEN the steam OS releases and is adopted. Sorry about that.
No riot game works on linux
Given their rivalry with Valve (I’m sure Riot see it as a rivalry at least, Valve probably don’t) I wouldn’t put it past Riot to want to avoid SteamOS and Linux by extension until significant market share is available.
