Sorry to cross-post, but I thought this would find better help in the nVidia section rather than GCRD now that I've established the problem.
I was running Flight Sim X on my MacBook Pro (running Vista) last weekend after doubling my RAM (4GB FTW!) and everything was going great. I noticed a HUGE increase in speed, and I was able to pull 25fps or so with most settings all the way up. Life was good.
Three days later, I boot back into Vista to do some more simming. Don't mess with anything, just load FSX after Vista finishes loading up. I run the exact same mission that I was doing before...and everything just grinds to a halt. I was getting literally <2 fps. WTF? I reboot, thinking its some random weirdness. Lo and behold, it does it again. The processor is throttling up to full speed correctly, and its plugged into the wall. Finally (with some help from thideras...thanks!), I establish that the PCIe Link Width is stuck at 1x. I try installing some driver OCing apps, hoping they might reset something that got screwed up in the driver, but nothing seems to help. After installing PowerStrip, it bumped up to 8x, but that still doesn't fix the problem (it needs to be at 16x). Any ideas?
I can't do a driver update as regular nVidia drivers don't work for the 8600GTM; only the Apple Boot Camp drivers will work. I could try reinstalling those, I suppose...
