If your using windows 8.1 make sure you install the Microsoft mouse fix for 8.1.These drivers are def an improvement for COD:GHOST however i'm stilling getting flickering and some choppiness. There is also a new issue where my mouse jumps around in this game. Aside from that everything else i'm playing works great.
I'm also having no issues with the overdrive and cfx panels as noted by others. I did a clean install manually removing reg keys and directories, performed a reboot ran driversweeper and ghostbuster, reboot one more time and install. Other than the fact that COD isn't completely fixed which is bumbing me out, the drivers worked great here.
