I played enshrouded and path of exile and Diablo and Elden ring coop and bg3 coop all with zero issues except on like the first few days of release if there are any.

The worst thing right now about Linux multiplayer gaming with anticheat is the release day experience. Or if it's a AAA title with heavy graphics expectations, odds are they use some weird directx fuckery that's not available in vulkan immediately and needs patching.

All of that gets fixed when Steam deck compatibility at launch day becomes more of a thing, so it's just a matter of time tbh. I've been using Linux dual-boot since Hardy Heron and as my sole OS since 2018, 2025 may be honestly the year of the Linux desktop no joke.
