Extreme mouse lag

Hi audi3murphy First thing to try if not done is check the web site for your mouse for a new driver. If this fails to fix it then try this...

Run the game as Administrator:
Go to the Origin games folder (C:\Program Files (x86)\Origin Games\Battlefield 3) and find Bf3.exe. Right click it and go to PROPERTIES, then COMPATIBILITY and check the box next to RUN THIS PROGRAM AS ADMINISTRATOR.
Do the same with BF3_x86.exe as well.

Run Origin as Administrator:
Go to C:\Program Files (x86)\Origin and right click on Origin.exe and go to properties. Then go to compatibility tab and check the box next to RUN AS ADMIN.

Disable Origin in game:
In Origin - Application settings - Origin in Game - disable Origin in game

Origin Cloud Storage turn it off
Origin, settings, General

If all this fails to fix it then try this...

BF3 folder in my documents holds game configs and screen shots even if BF3 is installed on different drive. When you uninstall BF3 it does NOT remove this folder. So when you install the game again you can still have the same issues. Or if the cfg has a issue this can fix it as well.

1- Go to my Documents and remove BF3 folder place it on your Desktop or trash.
2- Be warned you do have to set up your in game settings again.
3-Repair BF3
4- When done go test your game.
