My pc specs- Pentuim 4 3.0Ghz w/HT 800 Mhz bus/1GB DDR2/7800 GTX graphics card/NEC 19" 8ms/550 watt PSU/

I'm trying to play Doom3 @1024x768 ultra quality and 16x AA, but it don't run smooth at all. I upgraded from a 6800 to the 7800 GTX so I could experience the best the game had to offer, but after spending $600 dollars for the Geforce 7800 GTX theres no increase in performance from the $200 dollar Geforce 6800. I even tryed 1024x768 with no AA and still the framerates were poor. It seems that for Doom3 to run at a high framerate I must turn the res to 800x600 with no AA. My 6800 can run very smooth at that same setting, so I ask you is there really a performance differance betwen the 7800 GTX and the Geforce 6800. BECAUSE I DO NOT SEE A DIFFERANCE!!!

PLEASE HEEELP ME!! :mad: :eek: :thumbdwn:

maybe your CPU limited?

Don't buy a high end card if you plan on playing at low resolutions.

As far as it not running smooth, whenever I upgrade any component in my computer I always reformat! Make sure to install chipset drivers also.

Thats odd man. I played doom3 on my 6800GT (oc'ed to Ultra) at 1280x1024 with 8xAA / 16xAF and it ran perfectly smooth (with maybe a hicup occasionally in huge areas with a lot of deamons).

Driver version would help. Did you use Driver cleaner beofre installing the new card? You also may need to delete the Doom3 config file.
