Thankfully, it looks like work is well underway, and game developers are already involved, too, according to Newman. The only way Valve can realistically do that is by helping anti-cheat developers solve the Proton problem. That means making every Windows game operational through Proton, not just a few special cases, by December.
Including testing of thousands of games, engaging with third parties, like anti-cheat providers, work targeting game compatibility, and more.' 'We are constantly building on Proton and there's a lot of work that has been done that doesn't yet affect the opublic verison of Proton. 'Our goal is for every game to work by the time we ship Steam Deck,' says Eric Petersen in a 'Steam Deck for Developers' video. Valve has set itself a goal of getting every Windows game working on the Steam Deck by the time it ships, whether it's fitted with anti-cheat software or not. The Steam Deck is already acting as an accelerant for Proton development, it seems, and specifically anti-cheat compatibility.
