One idea may be to look up and >download an OLDER driver and see if thathelps.I tried FS right after re-installing windows, but before I downloaded all of the updates, and it stuttered. I tried it again after the updates, and it continued to stutter. I am using the newest NVIDIA driver right now.

It looks like it will have the same affect as FS Autostart, but maybe better since I tend to leave programs running when I don't really know what they are, and sometimes FS Autostart doesn't know either. I'll give it a try.>My experience is that rapid stuttering is tied to the video driver.>Try another driver release if you can.. it may help.>Also, as a test, lower AA and AF settings and maybe screen >resolution, just to see what impact it has.I have lowered my screen resolution to 800 X 600, and gone so far as to turn my AA down to 2X, and I tried it off as well. I don't have AF on in my card or in FS9 right now, but have tried it at all settings up to 16X. My experience with the stuttering did not change, but I did find the simulator to become unstable at 8X AA.>Slow, intermittent stuttering is usually caused by some background >program, like anti-virus monitoring, kicking in.>Running Filemon concurrent with FS9 will show you if other programs >are interfering.Someone just sent me an e-mail wondering if I have tried Filemon...

Well, thanks for the help everyone. Filemon just solved my two month long problem in about 10 seconds. Apparently a program was trying to run that I don't even have anymore. For some reason my old TVI card, that I removed already, kept trying to start up. I removed all associated files I could find and now I am stutter free.Thanks for all the help.

Have you done a "remove hardware" on this tv card ?Glad you have fix your problem - mind you, you have fixedyour problem - so maybe to do nothing and enjoy is the bestoption.RegardsTom

I may not have stuttoring, but i am always looking for ways to better maintain my system. That sounds handy. :-)
