[Wine] Gothic became slow on keyboard input

[Frag91]

Hi, i've a weird problem.
I'm playing gothic , installation works fine and the music too.

So, that's the problem:

When the character is motionless, and i look around with the mouse, the framerate increase a lot!
But when i look around with the keyboard, doing the same movements with the mouse, the framerate decrease a lot.

It seems there's something wrong with the keyboard input. Any suggestions?
dll replacements etc..

My system:
Intel Core 2 duo e6850
nvidia 8800 GT whit nvidia drivers 173.14.05
2GB ram

OpenSuse 11 with kde 3.5

output of glxgears:
71323 frames in 5.0 seconds = 14264.551 FPS
71639 frames in 5.0 seconds = 14327.697 FPS
72102 frames in 5.0 seconds = 14420.305 FPS
