Can I set my Optimus Nvidia card to run Unity3D with bumblebee?
- by manuhalo
I'd like to know whether I can run compiz on my Nvidia card to speed things up. It's a Dell XPS15 laptop but I'm mostly using it as a desktop, so battery life is not important. Apparently my Intel integrated card is able to run unity 3D, but my Nvidia GT 420M is not. Here's the output of unity_support_test, both with optirun and without it:

Any ideas of why this is happening? Thanks in advance to anyone able to shed some light on this.
What I have tried:
Installed the v290 drivers from the x-stable PPA.
Tried forcing Unity-3D to work by telling Unity to ignore the unity-support-test results
i.e.
gksudo gedit /etc/environment
add the following UNITY_FORCE_START=1 to the end of the file.
