After installing Ubuntu 12.04 and Bumblebee, I tested out the performance of the Nvidia card using Minecraft and a few other games. I've noticed it to be way slower than it was on Windows 7. Is this normal? I'm using the GT 630m. From what I've read online, nobody has said it to be slower than Windows. I'm just really curious because I want to use Linux so much more than Windows, but if I don't get the same performance I feel really picky.

The Nvidia card is still faster than my Intel graphics on Ubuntu, but it's not as fast as it was for my on Windows.

I get 60 - 80 fps on Minecraft on windows, while I get 28 - 48 fps on Ubuntu.

Any Ideas why? Thanks so much!
