UT 2004 is jittery, im not evan online!

So i got UT 2004 about a week ago and love it. only one problem, Its jumpy as hell! I dont know how many times i have died because the damn game dedcides to suddenly not pay attention to me trying to shoot the enemy and runs me straight into a corner. Does anyone else have this problem? Is my system just not quite up to spec for the game? whats the deal?

*Specs*
AMD Barton 2600+ CPU
DFI Nforce2 ultra B Motherboard, CMOS reloded

Corsair DDRAM 512MBTWINX512-2700LL COR RT

latest drivers for everything?
There are new nForce drivers that were released a few weeks back.

 

Try turning off texture pre-caching. It might also be called something like pre-loading of player skins.

 

Thanks Wyatt_Earp. problem solved.
