Ubuntu 12.04 - Optirun - Nvidia Experimental 310
I have a notebook, DELL XPS L502X with an Nvidia GT540m 2gb.
In it, I'm using Ubuntu 12.04 x64, along with Bumblebee / Optirun experimental Nvidia driver (310) - recommended by Steam.
The problem so far is:
In Windows (dual boot), I run Trine 2 for 50 ~ 70 FPS.
On Linux, it runs at 10 ~ 15 FPS.
With that I'm not sure if the "optirun" is working (already tested the optirun and is working)

I have also tested it with the "primusrun" and is working well.
But on Steam, everything is extremely slow.
You know why?
