Strange mouse acceleration fix

When this happens, your mouse-sensitivity speeds up out of nowhere. Not everyone has this bug, it depends on the type of mouse you are using.

STEP 1:
To fix this, navigate to your cod ghosts installation folder.
For example: "YOUR DRIVE\SteamApps\common\Call of Duty Ghosts\players2

STEP 2:
If you are having this bug in multiplayer, open up config_mp.cfg.
If you are having this bug in singleplayer, open up config.cfg

STEP 3:
Search for seta r_elevatedPriority. This is by default "1". Change it to "0"
Before: seta r_elevatedPriority "1"
After: seta r_elevatedPriority "0"

STEP 4:
Save the file, and restart you game!
Easy, simple, enjoy!

This worked for me, I hope it also does for you :)
Good luck!
