Is there mouse acceleration in MW3? If so, how can I disable it?

Mouse acceleration (also called "Enhance pointer precision") is a feature in which the distanced moved by the on-screen pointer is not simply proportional to the distanced moved by the mouse. Instead, it also takes mouse speed into account.

I have mouse acceleration disabled in my Windows 7, but I'm under the impression that this effect is still happening as I play Modern Warfare 3. Does anyone know if the game implements its own version of mouse acceleration? If so, how can I disable it?

The "Smooth Mouse" option is also already disabled for me.

Solution 1:

Yes, there is an acceleration setting, it's in the line: seta cl_mouseAccel "0" in the config file, stored in: \Steam\steamapps\common\call of duty modern warfare 3\players2
(if you don't use Steam, the route will be different, of course)

That didn't work for me, since it was already set to 0. This is what did the trick: With the game running, Task Manager -> Details -> iw3mp.exe -> set priority -> normal.

I have a considerable level of knowledge about how an Operating System works, and I can only vaguely guess why this is happening.
