    So I have a 15 inch MacBook pro and Star craft 2 runs fine but the frame rates are a bit high and it can get really hot. Ive read that if you can reduce heat and increase the battery life by reducing the frame rate. I've herd that their is a way to reduce to the frame rates by finding a file named Variables. I have not been able to find the file now and I herd that it changes location periodically. Could you guys help?

    If you have Lion then finding the variables.txt can be a little tricker.. you need to run the following terminal command to show your library again:

    chflags nohidden ~/Library/

    If your running an OS older than lion it's easy .. goto your library/application support/Blizzard/Starcraft 2 and the .txt should be there.

    After finding your variables.txt you want to find the lines:

    and change their value to a desired fps that you don't want your computer to exceed. If these two line don't exist then you can simply add them in and it'll work just fine.

    Btw.. if your running this on a macbook then it's normal for the temperature to get a little high, especially on the unibodies. You shouldn't really be worrying unless your temps frequently exceed 90 celsius. The cpu's in these computers are rated to 105 celsius.

    Edit: Oh.. and if you mean heat as in how the computer is to the touch then thats also normal in unibodies.. the metal case is designed to be one big heatsink.

    The Ivory Tower (I'm not coming down)
    This is a pointless thing to do. Even if you reduce the frame rate your machine is going to get hot when playing SC2.

    I understand that it could have little to no effect but I am still willing to try it out. Anyone have the answer to my previous question?

    Your Library folder is in your user folder. Username/library/application support/Blizzard/Starcraft 2. But the only noticeable change you might see from capping your framerate is worse performance.

    Not necessarily, I've done this with several games and the temperature definitely decreased. Some even have a frame rate cap built into the settings.

    So I have tried searching all of the suggested folder locations in finder and I can't find variables. I have done the terminal that you guys said too. Have I done something wrong or is the folder in a different location then most?

    Are you able to get to your application support folder?

    Also you keep calling the variables.txt a folder. It is not. It's a text file.
