My guess is he wont Gonzo
My system is a p4 1.5GHz 1Gb RDRAM and a GeForce2 on WinXP
I get around 75fps in solo flight and hover round the mid 30's in low furball my guess is you should be seeing only slightly lower than that, deffinetly not single digits.
I play at 1280x1024, 32bit, unlimited. You might double check the video settings in AH and maybe take the resolution down a notch unless your already at 800x600(you should be very playable at that setting) also check what driver you are using and make sure it is up to date, that may help.
