My mx300 broke down and after I bought another mouse, the first thing I saw is that it's uber fast on default windows sensitivity, literally one small movement of the mouse sent it to the other side of the screen, making it impossible to do anything sensible. So I set default sensitivity to the lowest possible value, which turned the new mouse into an almost ok thing.

However in a while I stumbled upon a couple of games that I couldn't play, because they managed to completely ignore windows sensitivity setting somehow, and my new mouse behaved like mad making it hard to even click stuff in the menu, let alone do anything more precise like aiming. Yet if I plug mx300 back in, it works like a charm, the pointer moves at a completely normal speed.

What is at fault? I want to buy a normal mouse, but they don't let you test them in stores, I'd love to know what parameters cause some mice to sport abnormally high sensitivity in comparison to other mice.
