I meant cursor motion is very blury, enough I can loose its location on the
screen. And for instance, while moving the dota2 map with the grab method, at 60Hz
it looks like moving the dota2 map at a sub-30Hz with some lag.

At 120/144Hz, cursor motion is way less blury, and dota2 map motion is smooth
with the grab method.
