Recently Microsoft has released a tool which can fix mouse lag issues in your favorite video games running in Windows 8.
Also Microsoft has released an update 2903939 that can fix mouse freezing or stuttering in games like the Call of Duty, Half Life 2 and Portal. If you experience freezing or spluttering download and install the update.
If the game you are playing is not in the list, there is a “Fix It” tool from Microsoft that should help. Download the tool and run it.
From the tool browse and select the executable game file and follow the instructions.
Restart the computer an run the game, you should not experience mouse lag issues.
Note that Microsoft asks to apply this fix only if the game is facing mouse lag issues, otherwise it will drain your laptop battery.
