Freezing and Stuttering

I've been getting painful stuttering issues during firefights in Sandstorm.
Video showing the issue:

You can see my FPS tank via the top right corner of the video.
Only been having the issue on this map/32 player server so far.
Anyone else been having issues?

Settings are all on high, no AA.

I like all the changes in the last patch but performance is what need to be improved now!
Im having the same problem in many maps.
