nvidia and ut2003 - wrong refresh rates

[LeVA <leva@az.isten.hu>]

Hi!

I'm trying to run ut2003 under linux with an nvidia driver, but 
everytime I start the game it switches to 800x600 @ 56 Hz, altough my 
monitor does support 1024x768 @ 85 Hz, and 800x600 @ 100 Hz (which I 
can not set up under X, because it alway switches to 800x600@85 Hz, but 
this doesn't matter now). So anyone else experiencing this strange 
refresh rate with nvidia driver while gaming? How could this be fixed?
In my console, when running ut2003, I also get these messages:

Xlib:  extension "XiG-SUNDRY-NONSTANDARD" missing on display ":0.0".
Xlib:  extension "XiG-SUNDRY-NONSTANDARD" missing on display ":0.0".
Xlib:  extension "XiG-SUNDRY-NONSTANDARD" missing on display ":0.0".

Hope that someone could help me with this.

Thanks!

Daniel
