I didn't make it!
I just bought a Barton 3200 with a manli GeForce 6800 128Mb 256 bits and 1024 Mb RAM (400 Mhz) and all I get in DooM 3 is ... 5 FPS.
I installed nVidia latest drivers (18.104.22.168), latest Direct X (9c) and I flashed my BIOS (motherboard is A7N8X-X).
Now I'm lost...I dunno where the problem can come from...maybe some settings in the BIOS, maybe something else.
Thanx in advance
Check if the resolution isn't too great, or if Anti Aliasing is set too high... If that doesn't help, then it's about hardware, and I don't know anything about it that could be helpful.
i heard on max settings, doom 3 takes up 512MBs of video memory, and u only have 128MBs on your 6800, so try lowering your settings, or as MBO said, check the resolution, anti aliasing and other gfx card settings, and you should get more fps then
