Hey i play a game called Wolfenstein:Enemy Territory and i have a geforce fx 5700 256mb lately ive been getting around 30-70 fps when i used to get much better around 180+ fps. It sometimes jumps to 180+ but only for a few seconds then it goes back down to 50, i have it capped at max fps 333 ive tryed reformatting my hard drive reinstalling drivers and nothing seems to work. Does anyone know how i can fix my problem?

what version of directx are you using and whats the driver you currently have installed for your graphics card?

For geforce try going on their web site and telling them the problem. you could also try posting a thread on graphics and cards part of the forum.
Also try reinstalling the game. Or try windos update (sometimes we accidently delet some driver upgrades and then we need to update our system again to bring it to the level)
Best of luck
