Hi,I have WinXP x64 (Final) and installed FS9.1 with Catalyst 5.4's. However, although I have nice high fps it seems as if its running in slow motion - it is not as "fast" as in XP 32bit if you know what i mean. It's very smooth but just runs as if in 1/2 speed mode. I have checked and it is in real-time mode. Also - the internal cockpit shows the controls respond quickly enough (e.g. the joystick in the cockpit) but the aircraft don't move around in the environment at full speed.Anyone else notice this? Any fixes?Thanks

That's odd, when I run 64BIT XP RC2, my FPS are the same but the sim is way smoother. I would try a reinstall of drivers and see if that helps anything? Other then that I do not really have any ideas.

Fixed it!! It was the power saving settings - changing it to minimal power management did it!So much smoother than in 32bit! Yey!All I can say is- loading times are significantly reduced, no stutters at all. Smooth!! Thats without the time spent on tweak FS9 too. Will be interesting to see further improvements.Thanks for your idea too Kurt.P.S. Please can someone move this post to hardware. Might be handy for someone with same troubles another time.

grrtT!what sys specs you got ?

It's a good thing I installed FS on a seperate partition, it will make upgrading the OS to the 64 bit version much easier!
