Choppy video/PCI ati 9250

[JB39]

I have a dell latitude (640M DDR, 1.8 G P4  docked to a c-dock/II.  I have a PCI slot in the dock running a 9250 ATI Radion 256 DDR. (Chip Type 9200 series/0x5960-DAC internal 500MHZ). My desktop is 1024 X 768, at 16 bit color.  My problem is When I get within gunning range of an enemy, the video becomes real choppy, and I can keep the sight on the target. It jumps around horrible.  The card is set to AH defaults.  What settings do you recommend?  Please help-  I have Directx9c.

Set the maximum texture size to 256, in the video setup of the game and see if that helps.
