When I set my in-game sensitivity (in Team Fortress 2) to 1.0 and my G9x's DPI to its maximum of 5700, I get about 3 inches per 360. When I halve my DPI to 2750 and double my in-game sensitivity to 2.0 to compensate, my inches/360 nearly doubles.
Shouldn't inches/360 = dpi*sensitivity? Why is this so dramatically not the case here?
I have all acceleration disabled and the game uses Raw Input.
