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

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

i have a guess.
When you are using 2 display devices with 2 different refresh rates, things get messy without exclusive mode
