I have a great custom build computer and mw3/mw2 has been running perfectly, compleately lag free. Today i logged on and suddenly it started to lag. Only when i move the mouse fast it lags... Any suggestions ? Please help me, Peace

Try to remember what did you do the day before?

or try to reset all settings to default.

especially controls

maype causeof your ping is high

Any weird drivers recently installed ? Or some third party software ?

Dont be rage, I miss the old alter at least for me and my friends worked fine with no lag, especially the idiot termilag map, weird lag sounds there too.

It even lags in the title screen... all settings low... when i dont move the mouse fast i have about 340 fps, according to fraps. i can run, throw equipment etc but now move the mouse. huge fps drops !

If you are running Win 7 or Win 8, try turning on High performance from Control pannel>>Power options

It might help.

Change process priority to normal in task manager
