(Polling rate >= 1000) Produce stuttering in all wine games

Post by zeioth » Sat Apr 06, 2019 12:49 pm

Description: Any game running over Wine will stutter under the next conditions:

How to reproduce
  • The polling rate on the mouse is 1000hz.
  • The player moves the camera.
  • The issue is solved when the mouse use a polling rate of 125hz
  • I recommend you to test this issue with the game Sekiro, since the issue is extremely noticeable in this game.
This issue doesn't affect linux native games. This fact has been tested with the games:
  • Bioshock: Infinite
  • Portal 1
This issue does Affect the next Wine (non DXVK) games:
  • Doom 2016
This issue does affect the next wine games:
  • Sekiro
  • Quake Champions
  • The witcher 3
  • Quake Champions
  • Paladins

If someone with knowledge how to fix this is EVER going to even set a status other than "unconfirmed" on this issue, you HAVE to post a bug on bugzilla.

When did it start happening?
Logs?
Bisect exct patch this happened with
Is it reproducible with a CLEAN wine-devel? No staging, esync, dxvk, proton++ cos wine devs cant do anything about that anyway.
And so on and so forth.

And if you ARE lucky and it is reproducible with a clean standard wine-devel, it might get fixed :)

Cybermax thank you for your response:

When did it start happening? Since forever, it affects all wine versions (I've tested from 3.16 to 4.5)

Logs? They don't show anything special, but here you have https://pastebin.com/raw/66UxXyHC

Bisect exct patch this happened with: This behaviour have been always there so there's nothing I can bisect.

Is it reproducible with a CLEAN wine-devel? No staging, esync, dxvk, proton++ cos wine devs cant do anything about that anyway:
Yes, I've tested Doom 2016 with pure wine 4.5, running it with the command:
WINEPREFIX="~/doom" "~/doom/drive_c/Games/Doom 2016/DOOMx64vk.exe" > ~/doom2016.log

Video showing the issue: https://youtu.be/5dAHbvSS-P8
from 0:00 to 0:20 - Polling rate 1000 -> You can see severe suttering in the frametimes graph.
from 0::20 to 0:20 - Polling rate 125 -> Everything is fine here.

(In case you were wondering, yes, the issue also happen when I'm not recording video)
