[help][solved] Getting input lag on Bazzite (lemmy.nz)

Hi all, I have recently installed Bazzite, after previously being on Nobara.

I have been playing Dave the Diver and DOOM (2016), both through Steam, and I get pretty serious input lag. A second or more delay at times, generally when FPS is struggling.

I'm running on a laptop with integrated graphics, so the struggling integrated GPU is not a surprise, but I didn't have this input lag issue with the same games on Nobara.

Any tips on a setting or something to help this?

I have lowered graphics settings to help with FPS, but ultimately I am not going to be able to avoid occasional FPS dips. The mouse input is instant, it's just an issue with the keyboard.

Any help appreciated!

Edit with solution: it seems the problem is IBus, see this comment: https://lemmy.nz/post/23401044/15684126

Basically the solution is to add IBUS_ENABLE_SYNC_MODE=2 to /etc/environment and restart.

Someone else had a similar problem and their fix may help.

Nice, that does seem to be the issue! By searching for that environment variable, I also found this: https://www.reddit.com/r/linux_gaming/comments/1eqrnjr/psa_recent_ibus_releases_introduce_noticeable/

It seems IBus is the cause of this lag. I have made the change as the post you linked suggested, and it seems to have fixed it! I found some people having issues with the value of 0 and so will try out for a while to see if the hybrid 2 value is stable.

I have Bazzite but for handhelds and I knew they did have some issues with input lag but couldn't remember the specifics. Glad I could help and that you found a solution that works.
