Some really good news for PC gamers everywhere, as it seems one small battle against invasive anti-cheat has been won.
Recently, DOOM Eternal gained the brand new Denuvo Anti-Cheat tech, which is not to be confused with their usual DRM tech. This addition entirely broke it in the Steam Play Proton compatibility later for Linux and enraged the wider PC community for being added after the game was already released. Just take a look at how the user reviews went on Steam…
On Reddit, id Software made a post to explain their plans for updating DOOM Eternal after the backlash. In the post they explained that the anti-cheat will be removed from the game in the next update. They also said that if/when they try again in future, at minimum they "must consider" that it will have the ability to play single-player without it.
Going even further than that, Michail Greshishchev, the Product Owner at Denuvo claims that Denuvo Anti-Cheat will actually support Proton in future releases. They mentioned this over on Valve's Proton GitHub issue tracker:
Denuvo Anti-Cheat will have Proton support out-of-the-box for releases beyond DOOM: Eternal. Feel free to @ me directly with feedback once you had a chance to try it. I'm happy access is restored for you guys.
It's not entirely clear if they mean it will work with online play, or just auto detect Proton to disable it for single-player parts of games. If they clear that up, we will let you know. Either way, it's good to see because Linux gaming is starting to have more attention paid to it.
DOOM Eternal can be found on Steam.
