Linux is all good if you only play singleplayer games. My friends started playing the finals yesterday and it doesn’t run on linux because of EAC. Windows can run all my games without any proton switching and all the nvidia features like ray reconstruction and pathtracing with frame generation just works (alan wake 2 looks so good).
It’s not boot time, but context switching (close apps and whatnot). I suppose I could hibernate, but I still lose access to my network services, like my kids’ Minecraft server and network shares. And then Windows usually has massive updates because I launch it so rarely.
If I play on Linux, I just launch the game, and that’s it.
Before Steam came to Linux, I just didn’t play games very often. Now that most games work, I can just push play and I’m in a game, so I play a lot more games.
