Use "RefreshLock" (available from the link you posted) or buy a digital monitor (assuming your video card has a digital output).
Understeer is when you hit a wall with the front of your car
Oversteer is when you hit the wall with the back of your car
Horsepower is how fast your car hits the wall
Torque is how far your car sends the wall across the field once you've hit it
It is not a bug, it's a feature (thank you Microsoft). MS decided to lock the refresh rate @60hz as standard and let applications choose their own rate. None do however.
I use [Only registered and activated users can see links. ] to lock refresh rates. However, this 'feature' is (was) meant to be removed with SP1.
i use powerstrip too which i find is pretty cool and a neat tool to use, the refresh lock at 60fps has NOT been fixed in SP1 so i guess u will have to continue downloading them unlocked drivers
