Getting stuttering with high FPS

[fnugen]

I've recently started to notice I get stutter in a game. I play mostly GTL, so this will be the reference. It shows in replay as well as game. I can be merrily cruising along with 45fps and I'll get a slide show stutter effect...not like it drops to 2fps, but just like it suddenly gets choppy, but yet I am showing a constant fps well within a range where it should be very smooth. The vidcard is a BFG 7800GSOC and my PC spec is AMD643500+ and 1gig OCZ ram in dual channel. I upgraded to the BFG from an ATI x800xl AIW and never once noticed this issue with the ATI card. Anybody offer some suggestions ?? It really does affect online play which is what I do mostly.

Have you enabled/disabled V-sync?

It was on, I must have forgotten to turn it off again when playing with different drivers. Will try the game again over the w/e, I'll be back if it doesn't make a difference. Thanks for the suggestion.
