Ever find yourself in a situation where for some inexplicable reason your mouse doesn't feel like it used to and shots that used to be easy now take an immense amount of effort to hit? Players you used to beat routinely are now giving you a hard time or even kicking your ass. etc

So you double check your config and sensitivity and all that stuff, trying to figure why this is happening. Nope, everything is fine. Got the same old sens, acceleration and Windows settings. But still something about the mouse feels a bit off.

So maybe you try changing mice or mouse pads. With one mouse you shaft like a pro but can't hit rockets to save your life. Another mouse gives you back your rocket aim but now your LG is all over the place.Eventually you'll find a combination that sort of works, but it's still not quite the same as it used to be.

"Why is this happening? What am I doing wrong? Maybe Windows Update screwed it up somehow. Is my USB port overclock still working? Maybe I should try reinstalling the Win7 acceleration fix. And maybe also reinstall the game. Ok, I guess I'll reinstall Windows too."

Welcome to mouse hell.
