It's not DRM in general, most DRM works on Linux. It's mandatory malware (the industry calls it Kernel-level Anti-Cheat, KAC for short) that's the problem. The malware doesn't support Linux, which is good because it shouldn't even exist in the first place, and refuses to work in virtual machines. It pretty much is only used in competitive FPS games.

The only issue I've seen is with anti cheat, like the ones Activision uses for call of duty.

It sort if solves itself though, you don't buy games that don't work on Linux therefore not supporting them. I ended up returning battlefield for example because booting into windows wasn't worth it, been happy playing arc raiders instead

Anecdotal, but I've never had issues with DRM on Linux. Even the most hated ones like Denuvo work fine. But as others have said, the biggest issue for gaming on Linux are multiplayer games with kernel-level anti-cheat.

Oddly it’s GOG games that gave me the most trouble. Steam has gone seamlessly with just a right click to select proton in compatibility for each game.

Lutris & Wine handled GOG.

Next up is seeing if ME Legendary and AC Odyssey will fxn.

But yes, I just had a conversation with someone last week. He bought a new Windows 11 laptop because his favorite games wouldn’t work when flipped his old one over to Linux.

The only obstacle is people supporting games with DRM.

For users, yeah. This is mostly about making things easier for the distro maintainers. Especially if they upstream all their patches, as that will then trickle down to all the other distros.
