I have been installing bumblebee and primus in order to play a few game on my laptop. When I test them with respectively
primusrun glxspheres, I see an adequate increase of the framerate in
primusrun run gives about the same rate as
glxspheres, not better.
It seems like primusrun doesn't use my Nvidia card or uses nouveau? Is there a configuration step for primus I missed? All I did was editing xorg.conf with the correct
BusID "PCI:01:00:0", using
lspci | grep NVIDIA (see http://ubuntuforums.org/showthread.php?t=2129405).
I am using up-to-date bumblebee, primus, nvidia-current drivers. The card is a nivida GT 620M. I don't know which information I should add but I'm here for more details!
Thanks for reading!
