With any luck windows won’t continue to allow kernel anti-cheat much longer either. I also assume that sooner or later there may be government action on kernel anti-cheat, since many of the popular games/anti-cheats are Chinese owned. If tiktok spying is enough of a concern to ban the app, it’s a pretty short logical step to being thinking that Chinese companies shouldn’t be allowed to install full access, unremovable backdoors on millions of PCs.
Many game engines let you make Linux builds, but there are still bugs and optimizations that have to be done manually to get it working. The video claims it takes ~6 months to make a proper port, and even then it might not run as smoothly as the windows proton version does.
