D901c, 2x8700MGT Shuttering on COD4

Hi,

I have a problem that is annoying me, especially when I've seen it not happening with other PC's. While playing COD4 at 1600x1050 I experience some stuttering on the image. Sometimes it manifests over the audio also.

I tried reducing the resolution and detail but it does not do much. This happens both with XP and VISTA. Also some people with just one 8700M GT on a M570RU tell me that they have no problems as such so the puzzle.

COD4 runs between 35 and 59 FPS. Sometimes is on the 59s and drops suddently to 37 or 40 with no apparent reason (that is when I experience it). For instance in an explosion, weapons firing or simply a new player comes into to my vision range is enough to start stuttering for less then a second.

If you don't have this problem please post the following:

* Video driver version
* Sound driver version

Any ideas are also welcome.

PS: I always thought that with game patches and new video drivers the problem would go away, but no sir. There are already out 5 game patches and my video driver on XP is 169.28 and in Vista is 169.17. Also my XP Setup has nothing but games and drivers installed.

 

Are you running any memory intensive processes in the background? Check taskmanager before you start CoD. Also check if you have a lot of HD activity when the frames drop.
