When I run anything with bumblebee it doesn't provide performance increase compared to running on the Intel integrated chip. Is this an indication of incorrectly installed drivers and settings or just drivers not working properly yet?
My Nvidia cars shows in lspci as:
09:00.0 3D controller: NVIDIA Corporation GK208M [GeForce GT 730M] (rev ff)
I have installed newest nvidia drivers (nvidia-337) and configured /etc/bumblebee/bumblebee.conf according to instructions like on this site to use the drivers.
The card seems to be detected by bumblebee without any problems.
Following output from few example runs of glxspheres64:

I am confused by this myself. The Bumblebee FAQ says, that it makes little sense to use the glxspheares output because of something about VirtualGL. I don't understand the issue, but so they say.
Check here: https://github.com/Bumblebee-Project/Bumblebee/wiki/FAQ#how-to-check-nvidia-card-performances--they-seems-low
If someone who has deeper knowledge in this could elaborate I'd be really happy.
