Bad stuttering in MW3....

[Elmy]

I am running a 6990+6970 all watercooled. The 2 cards are on their own quad radiator on their own loop with fans in push pull config and temps stay around 38c.

Running a 2600K @ 5.0 GHZ and 8 gigs of Kingston Ram is running DDR3-2133 cas 9

Just seeing if anyone can tell me how to fix it....

Running 12.1 drivers with the CAP 1

Stuttering is abnormally bad. I get it in some other games but it is barely noticeable.

BF3 runs really smooth @ 5760 X 1080p between 60-100 fps on Ultra....

Well I just updated to the 12.3 RC Preview with 12.1 Cap3's and it seems to be better than what it was but it still stutters. At least its a little more tolerable....

hmmm... can you run it with only 1 GPU?

It sounds like a driver issue. I'm running a much older system than yourself and it runs fine for me. I'm guessing it's a crossfire bug

Turn off any GPU/CPU monitoring crap in the background as sometimes that can cause stuttering. Also one thing that caused bad stuttering for me int he past was my mouse over sampling. With my Logitech lazer mouse i had the sampling (DPI) super high and when i turned it down to normal levels it was stuttering was near gone.

Is this multiplayer? If so, strict/moderate NAT can lead to bad stutter.

Yes it is Multiplayer.... I have a static ip and there is no enable UPNP in my router config to open my NAT up and everytime I've called comcast they fail at trying to fix it....
