This proton isn't affiliated with the one you're talking about. Proton is a tool that valve developed based on wine that lets windows games run on Linux, especially the steamdeck
I wish you answer me one more question. I bought games on steam that later found they're "Windows only". I can't play these games on the steam I installed on my linux pc. I can only play them on the steam of my windows pc.
Can I play them on linux using Proton? If yes, then this might allow me remove windows from my life completely
Yes you can, on Linux steam, go to the game's properties, then click on the compatibility tab, and finally check the"force the use of..." Line. You should then be able to install the windows game on Linux and play it using the proton tool automatically
If you can't find that tab, it could also be because you need to go to steam settings and enable steam play for all titles (which will let you use Proton with any game)
If it runs, you’ll find reports on what it took to make it happen, if anything, and how well it runs
Kind of wish those comments/reports were curated better though, as they get old fast, and may contradict themselves after a certain time, offering what is now bad advice.
You kind of learn not to look at the older comments when you're looking for a particular game.
Look the games up in protondb for user experiences. Also Proton is not a Garantie. I have a great experience with proton and steam deck is running with proton, so valve makes money with proton and improve it daily. But it is NOT A SURE THING.
Again great tool, but it has a limit. E.g. valorant doesn't run.
Some games proton might not be enabled by default - on Linux go into the steam game settings for the game you want, click the compatibility page, and check the box "Force the use of a specific Steam Play compatibility tool", select the version - if one doesn't work, try another - proton 8 is a good start, proton experimental is usually a good second option. Wait for steam to download proton if it hasn't already, and the game should now play like normal
Note: some games might require additional configuration, or custom versions of proton to work. Other games won't work due to anticheat.
https://www.ProtonDB.com is a good option to check on games and see how to get the more complicated ones running.
Yep, even if the game is Windows only and you're a Linux guy, you go into the Steam properties/settings for that game, click on the Compatibility tab, and then check the "Force the use of a specific Steam Play compatibility tool". Chances are the game will work fine, but if it doesn't you can try some other version of Proton. Alternatively, there is also Wine but I didn't touch it yet and heard it's a pain in the a**
