Fix: Borderlands 2, FEAR, etc - Lagging Logitech Mouse / Keyboard

Device Manager
This doesn't happen on all operating systems. It happens on Windows Vista, Windows 7, and Windows 8 Consumer Preview. It can be 32-bit (x86) and 64-bit (x64). Note that it does NOT happen on Windows XP or Windows 2000.
This really is a shame since Logitech makes fantastic accessories so it's too bad their drivers are causing issues. Want some good news though? It is easy to fix!
Fix Borderlands 2 Lagging / Stuttering
1) Load Device Manager through Start -> Run -- devmgmt.msc
2) Locate the listings Human Interface Devices and disable ALL that say HID-compliant device
3) Try the game! Still not working? Move to step 4.
4) If you have "HID-compliant consumer control device" listed, then disable that too.
5) Still not working? Restart the computer and try running the game again.
If that STILL didn't work for you, then be sure to enable all the disabled listings.
Hopefully it DID work for you! Good luck!
