I have two PC's with nvidia GPU but I'm seeing radically diffrent Present Times:

- GTS450 (ddr5): Present time is usually between 0.1 to 0.2ms in both Exclusive and Windowed Mode
- GTX550Ti (ddr5): Present time is usually between 0.1 to 0.2ms in Exclusive Mode but blows out to 10 - 30ms (eg 100 times slower) in Windowed Mode so it drops frames.

I've tried updating Drivers, Bios etc on the GTX550Ti but I have No Idea why the very high Present Times in Windowed Mode on this unit - any hints?

Thanks
Nathan

Edit: Even my Laptop with a 320M has OK present times.....
