Hi,Just re-installed FS2004 after a fresh install on Win XP and have 1 very annoying problem:When I'm moving along a runway, my FPS drop to about 1 frame every 2 seconds, absolutely unusable.The second the wheels get off the tarmac, all returns to normal.The second I land, drops to ridiculous levels again.If I'm stationary on a runway, no probs - they only develop when the aircraft starts moving.If I land a seaplane (wheels up) in the sea, no probs. If I'm taxiing along in the sea, all is fine unless I lower the gear, at which point the problems arise all over again.I've tried changing every setting, tried reinstalling FS2004, got the latest Nvidia drivers, etc. but nothing seems to cure it.Interestingly, my brother had the same problem a few months ago (mine was woking fine at the time) and he never got it solved.Any suggestions VERY much appreciated.Thanks.

I haven't played much with the seaplane but was under the impression that the gear should not be lowered when landing in water? If you are not using any add ons then you might check that any previous graphics drivers and associated software were uninstalled before installing the latest drivers and software. I assume that the reinstall was because this problem existed previously? Was it OK until installing the latest drivers? Or maybe even a previous update of drivers caused it?

If you have a f.f. joystick try disable it. This has been a peoblem for some people with f.f. joysticks. hope this helps keith:-beerchug

Thanks all,It turns out I just had to disable the "ground bumps" part of the force-feedback andd all is fine now.Cheers.
