AreWeAntiCheatYet VS holoiso

I only really play single player, but I have run into this too. This is a great resource to keep track of progress - https://areweanticheatyet.com/

It varies by game. https://areweanticheatyet.com/ is an interesting resource for that because they also track announcements by developers about whether or not linux support is eventually planned.

Apart from that, Linux gaming is actually there, except for some anticheat enabled games : https://areweanticheatyet.com/

For "normal" games you could look yourself using ProtonDB regarding every game released on Steam and AreWeAntiCheatYet for most multiplayer games. If a game isn't available on Steam you have three possibilities. First if it's available on GOG, Epic Games or Amazon Gaming, you could use the Heroic Games Launcher. Second you could try to run the launchers through Steam itself using once again Proton. Third you could try installing it with a script or tutorial in Lutris or Bottles.

The only caveat to that is online games with anti-cheat. EAC and BattlEye both support Linux but requires studios to tick a box, many of which refuse. Any kernel-layer AC that doesn't have a userspace component will not run on Linux. Can see a list of games and their AC support here.

> except Multiplayer online games

That's no longer the case. I'd say about now, there are more multiplayer games that you can play, as opposed to ones you can't play.

See: https://areweanticheatyet.com/ as reference, but it's not very up-to-date, so https://www.protondb.com/ would probably be a better reference.

Nope, just works. There are some games that use invasive kernel-level anticheat that wont work as Linux sensibly blocks anything that shouldn't be messing with the kernel, but I'm not personally interested in those games anyway. EAC and Battleye both support Linux, but requires devs to tick a box, which there's several that can't be bothered.

A surprisingly big number of anti-cheat games work on Proton:

exclusive to the deck for now, unofficial ports exist, and official support is coming soontm

Seems like SteamOS is worth keeping an eye on. https://github.com/theVakhovskeIsTaken/holoiso Support for non-Steam Deck hardware should be coming soon.

HoloISO with built in Nvidia driver

Unofficially: Yes, via HoloISO. You can find plenty of YouTube videos about it showcasing the install process and how it performs on various hardware.

No to discount your work and this tutorial (in fact very much appreciated), but you could just use holoISO on that pc and turn it into a steam deck.

You might also want to consider installing HoloISO which is basically just a mutable version of SteamOS.
