Weird problem with OpenGl based games (Quake 3 engine)

James Huk · Post by **James Huk** » Wed May 14, 2008 3:14 pm

I will try to explain the best I can - but honestly... it may be hard to
understand what I am talking about anyway...

Problem is like this - whatever I try to play OpenGL based game that uses
Quake 3 engine I got weird mouse "jumps". Let's take Soldier of Fortune 2
Demo as it can be downloaded for free. When in jungle I try to look left or
right - mouse jumps slightly (the transition of the cross hair not smooth)
and it is very hard to hit anything. This is not performance problem – I got
hundreds of FPS, also this does not occur under Cedega or earlier Wine (I
remember I tried wine-0.9.15 or something near that – this problem was not
there). Any suggestions?

My PC:

ECS K7VTA3B KT333
Duron 1200
384 MB RAM
GeForce 5200 128 MB (Nvidia 9755 driver installed – same problems with
newest driver)
SoundBlaster 5.1 Live!

Powered by Debian 4.0 - ETCH

Hi,

I have tried to reproduce this using the Soldier of Fortune II Demo (using Wine 1.0 rc1) and am not seeing this issue. However, I am using a laptop PC, so it may be an issue with using a mouse instead of a touchpad.

Also, there is an issue in that relative mouse movements are not being reported by the desktop (X11) that should be addressed in a future update of the desktop. This issue impacts several games and could be what you are experiencing.

What version of wine are you using?

You may also want to see if there are any existing or similar issues in bugzilla. You may also want to add test results to the application database (AppDB), as I have found that the results submitted for Soldier are using very old versions. Doing these things will help the developers and other users.

I'm sorry I could not be of more help.

Some parts of Wine's opengl might be interfering with mouse by holding lock for too long. Unfortunately there is no simple solution since it does not happen on all configurations.
Your best bet would be using native Linux versions of those games. That's what they were made for in the first place.

have you tried running a regression test ?
