Stuttering in Doom 3?

I recently got a 7950GT 512MB (because my 7900GT died and evga upgraded me), and I've noticed that Doom 3 stutters at times. I'll get consistent 50-60fps, and then it will just drop to 15 or so for a few seconds, and it does it randomly, it's not necessarily just from enemies on screen or anything. I figured maybe it was because the textures are large in Ultra Quality, so I dropped it down to High Quality, but it still does it.

Now, I would be under the impression that a 7950GT should plow through Doom 3, and for the most part it does, except for those occaisional drops. I can be fighting 5 people, and it will stay over 50fps, then I'll just be walking down a hall and it will just nose dive :(

Specs are in sig, except the 7900GT is a 7950GT. Oh, and I don't remember if it stuttered or not on my 7900GT, because I hadn't played it in a while, but I think I would remember if it did though.
 
You should be getting higher than 50-60 fps in doom 3 with that card unless you have an outrageous amount of aa at a high resolution. Id delete drivers, run driver cleaner and reinstall.
 
do you have the dual core patch installed? my pc would do that same thing with games, dvds, etc until i used the amd dual core patch.
 
I'm running 1280x1024 w/ 2xAA =/

And yes, it is capped at 60fps. I don't know how to turn that off, but it doesn't matter, because my refresh rate is 60hz anyway.

I think I installed the AMD patch, but I may have forgot to do it last time I formatted, I'll check though. And I'll re-install drivers/cleaners/etc

Thanks for the tips.
 
Well, I updated my chipset and gpu drivers, as well as re-installed the AMD driver and re-applied the MS Hotfix, and so far, it seems to be completely smooth on Ultra @ 1280x1024 w/ 4xAA and 16xAF.

Dunno exactly know which fixed it, but thanks.
 
Well, I was wrong. I guess I just didn't play long enough last night, but it still stutters and it's quite annoying. Any other suggestions? Could it be because I'm using a RAM divider? Someone told me it gave a slight decrease in performance before, but I don't know :confused:
 
Might want to check audio drivers or audio quality settings. Sometimes a problem in this area will result in a stutter every time a new sound effect is loaded during the game. Look/listen as you play to see if it might be timed with a sound effect.

HL2 is notorious for stuttering

Not when I used my 7900GT. But it's not really a "stutter" in HL:2, it's more like a "trip". For like 3-5 seconds it will just drop real low in FPS. I would consider a stutter to be more of a brief 1 second jerkiness.

My SC drivers are up to date as well, but I'll try using my onboard sound tomorrow to see if that helps.
