Yeah i'm sure that can definetly handle it. My geforce 2 mx 400 could lol.
Its definetly something to do with the res then i'd say.
Yea try doing what rakedog said and try updatin the video drivers from the Nvidia site.
I think the game uses Direct-x 8, so, go to Start, Run, and type DxDiag. Check that you have direct-x 8 or higher. I'd prefrably go to the direct-x site and download the latest 9.c if possible.
Hope the problem goes lol,
