First of all, here is my setup....everything is stock.

Shuttle SN25P
A64 3200+ Venice
1GB (512x2) Patriot XBLK
BBA x800xl /w cat 5.9
2005fpw

I can not seem to get a decent framerate in Doom 3 (v1.3) at the native resolution (1680x1050). I have the game set to high quality (not ultra) and no AA / 8xAF within the game. IIRC, I have seen benchmarks where high quality is set along with 4xAA/8xAF and still got around 30-40 fps. In my case, I am getting somewhere in the teens and it sometimes dips down to single digit fps. The only other game I have installed at the moment is HL2 and CSS and I get 80-90 fps with everything on high and 6xAA/16xAF. I have checked both driver and game settings and can't seem to figure out what is going wrong. I have reinstalled the game but that did not help. Any help would be appreciated.

Do you have the latest BIOS and chipset drivers installed for your system?

What AA level do you have set in the driver? Also is Catalyst AI enabled?

Doom3 takes up some serious ram, so be sure that Doom 3 is the only application you are running.
