I'm not sure whether this is caused by other things, but after installing the Detonator, and tweaking it around a bit (as guided by Tweak3D), D3D games experienced lagging from input devices. For example, in Need for speed 3, say, I press the left key for 1 second, and then release it, the car will move to the left after one second I release it. Same goes to the mouse. Do a circle, and the pointer will move circularly only after 1 second or so.

Any resolves?
