I have been installing bumblebee and primus in order to play a few game on my laptop. When I test them with respectively optirun glxspheres
primusrun glxspheres
, I see an adequate increase of the framerate in optirun
but 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!
primusrun glxspheres
: both are working, but as slow asglxspheres
alone.
