My laptop has 2 GPUs, one of them is the default Intel HD Graphics 3000, and the other the Nvidia Geforce GT 630M. Obviously I want to use the 630M to play my games. How can I assure this is happening? When I go into Start → Run → dxdiag and look at the Display tab, it says that I am using the Intel HD Graphics Family for the display. Does this mean it is being used for games too?

What OS are you using? –  Breakthrough Apr 2 '13 at 1:06

In the Nvidia Control Panel you can specify which GPU to use on a per EXE basis, or which once is on by default. If you are getting poor performance add your game's EXE to the list under Program Settings or temporary change the value in Global Settings.

I know for Minecraft I had to add Java.exe to my program settings list for it to use the better GPU while running the game.

Thanks for the reply buddy, I'll give that a try - do you know if there is anyway to literally just disable the intel one or make sure that the 630m is default for everything? –  Billy Apr 1 '13 at 22:33
    
Yes, under Global Settings select High performance NVIDIA processor. Note that you will have a shorter battery life when you are not plugged in and a higher average temperature as programs that don't need the hotter, more power hungry, GPU will still use it anyway. If you are getting bad FPS, then force it to the Nvidia GPU, otherwise just let it autoselect. –  Scott Chamberlain Apr 1 '13 at 23:09
