Here some tweaks to improve framerate.

YOu need to d/l not only the kegetys file, but d/l the nasao and lowtex zips.

the zips you extract to the install directory so you have two new folders nassao and lowtex.

I'm sure the guide was straight forward.

Goto steam library, right-click CoD and select properties, select "set launce options" and write -mod=nossao -mod=lowtex.
