Nvidia 9600M GT doesn't work

Question

Hello,
First, I would like to tell you I'm a French girl and my english isn't very very good so... be lenient please
This is my problem : 2 weeks ago I reinstall a game (World Of Warcraft). When I started it, it was slow, run with low FPS (frame per second) so it was impossible to play.
My machine is a MBP with two graphics cards Nvidia 9400M + Nvidia 9600M GT, RAM 4Go-DDR3, Intel Core 2 Duo...
I've look many forums, most of them tell that it is necessary to select "Higher Performance" in System Preferences > Energy Saver.
I did that, but my game remains with low FPS.
I think the game doesn't use both cards. Maybe Nvidia 9600M GT doesn't work, I don't know.
So, if you know a manipulation to force the MBP to use the second graphic card, thank you to reply me :]

Hi, Mazima. The MBP can't use both GPUs at once — it always uses one or the other. If you've switched to the Higher Performance setting in Energy Saver and can play the game at all, your 9600M GT is working. But if it hasn't made a dramatic difference in frame rates when you're playing WoW, there's something else going on.
IS WoW the only thing running on your computer? If not, quit all other applications and see whether that helps with your frame rates. Experiment with different settings within the game. And see whether you can find any useful information in WoW's own forums, assuming there are forums related to it.
