I too have noticed a increase in FPS, it happend about the same time i turned off ground clutter, so its hard to say whether it's just the ground clutter being turned off or not. I have a hunch there is an minor FPS increase.
As for jerky graphics when plane rolls (ie barrel roll) i havent noticed.
What does your frame-rate indicator say? (remember its a time-average so you may want to roll for a dozen times or so - offline)
Also any diff between online and offline?
All i can suggest, maybe try to re-install direct-X to 7A i know 7 had USB probs, it may be that - do you use USB?
Also put the latest video drivers on AFTER you re-install direct-x
It could be your video card aint up to it. Does it happen in lower resolution modes? Colour depths?
You machine sounds more than enuf.
