In what situations is this a blocker for gaming? Like, genuinely, who actually had any significant issues from it? Top 1% Counter Strike pros? I've been playing games on Wayland for ages and I never understood how anyone can think the experience is worse, let alone so bad it's unusable.
I play a lot of FPS and third-person games so input latency is incredibly important to me. Honestly, once you try gaming in a truly low-latency environment (VRR, high refresh rate), it's hard to go back. Every time I try gaming in KDE Wayland on Radeon 680M, I notice mouse input lag and bad frame pacing.
The only Wayland compositor that I know of that doesn't exhibit these issues is the one used on the Steam Deck, but I am guessing there's some special sauce there.
It's not a huge amount of latency, so it's probably not super noticible to people who don't pay much attention. I'm pretty sensitive to input lag, and it does feel noticeably worse than both X11 without compositing and windows.
It is possible to get decent latency currently, with VRR + mailbox + fps cap, but there is still no VRR support if you use gnome.
I had an issue with it on nvidia. no matter what I did I couldnt get fps above my screens refresh rate despite vsync being off in game, it was being forced by xwayland. I dont have the same issue with my AMD card though.
Most likely FPS games but probably any kind of game where you need a fast response time. I understand that some people don't notice input lag with vsync on, but for me it's unusable. I'm not even close to the "Top 1% Counter Strike pros" but when I'm playing Portal 2, CrossCode, Deep Rock Galactic, Valheim, CS Go, Path of Exile, etc, it bothers me A LOT.
