COD MW2 mouse problems

[AFC]

Hi. After the last update my game became unplayable, started having jerky movement. It feels like the mouse sensitivity changes during gameplay and it's really annoying. The mouse only shows this behaviour on COD MW2 and i've seen other people complaining about this with diferent mice. Like i said before the the last update on january 18 i had no problems.

Have same problem.

UPD.
I think I got solved the problem.
In Windows Task Manager (Ctrl+Shift+Esc) change to use only CPU0 (or CPU1) for processes:
Steam.exe
GameOverlayUI.exe
iw4sp.exe

May be only iw4sp.exe will enough, need to check.

Guys, sorry I have no idea :(

Up.

Disabling multicore for process iw4sp.exe is fixing problem with mouse but do a little less fps.

May be is other ways to solve the problem? Any Ideas?

Disable V-Sync. Worked for me.

[Bulko (RUS)]

Was disabled by default.
Will try to enable->play->disable->play.

Cant change in specops )))

I think bug fixed by last update wich was downloaded today.
No mouse lags in multicore with vsync off.

[Bulko (RUS)]

UPD. Sometime mouse lags back. 1 time at longtime play it started to lag.
Second time just at start.

1st time fixed by disable multicore.
2nd by disable avast antivirus.

Dn what to do.

This is my problem sniping before Monday's patch 1-18-10 I could scope in and shoot but now not its a no go I have to sit in scope for a bit and it does it with smg/assault guns too or when im following someone with my sights it seems to just slow down and then the shots seem to just go right through them randomly.

I have been having trouble with my mouse and keyboard as well; when ever there is smoke on the screen, my keyboard and mouse locks up. This means that if I was shooting at the time, I'll keep shooting, while being unable to aim, and at the same time the keyboard locks up. So if I was moving, I would keep moving. This makes the game nearly unplayable.

I this has been going on since the last patch; before then, everything was fine.

I'm running Windows 7 Professional x64, with a Razer Lachesis on a Macbook Pro (late 2008 model)
