If you want to get a better idea of the graphics performance of your Mac running Call of Duty: Black Ops, it’s nice to be able to see how many Frames Per Second (FPS) are being rendered.
There’s a nice hidden feature to show the FPS in the upper right corner of the screen while playing the game. To do this, you’ll need to find a configuration file and make a simple edit.
The file (single player mode) is called config.cfg. For the multiplayer version, it’s config_mp.cfg.
1. Find the File
Look for the file here:
~/Library/Application Support/Call of Duty Black Ops/players/
“~” represents your user home folder. You may need to use the “Go to Folder” command in Finder as the Library folder is invisible by default.
Depending on the version of the game you have installed, it may be in a different location. If you don’t find it in the above location, try this:
~/Library/Containers/Containers/com.aspyr……/Data/Library/Call of Duty Black Ops/players/
2. Edit the File
Open the file in TextEdit or your favorite text editor and find this line:
seta cg_drawFPS “Off”
Change this to:
seta cg_drawFPS “1″
Save the file.
3. Lock the File
If you start up Black Ops now, the config file will simply be overwritten. To prevent this from happening, set the file to read-only (right click or Ctrl-click on it, select Get Info, Sharing and Permissions). Now when you start the game, the changes should take effect.
Keep in mind that with the config file locked, you won’t be able to save your progress in SIngle Player Mode.
