Bumblebee performance is too slow

Hi everyone,

This is my second post in this forum and it has been only 2 days that I met Arch. Before, I was using Ubuntu for 3 years, but due to low performance in my PC, unfortunately, I decided to say good bye which was hard to say.

Now, I am trying to have the same setup as my previous laptop and Bumblebee was one of them. I followed the instructions here: https://wiki.archlinux.org/index.php/Bumblebee.

It seems that bumblebee is installed and working, however, the FPS is too slow:

$ optirun glxspheres64 -info               
Polygons in scene: 62464
Visual ID of window: 0x20
Context is Direct
OpenGL Renderer: GeForce GT 520MX/PCIe/SSE2
0.023848 frames/sec - 0.021114 Mpixels/sec

Without optirun I get:

$ glxspheres64 -info              
Polygons in scene: 62464
Visual ID of window: 0x20
Context is Direct
OpenGL Renderer: Mesa DRI Intel(R) Sandybridge Mobile
0.033237 frames/sec - 0.029426 Mpixels/sec
0.029968 frames/sec - 0.026533 Mpixels/sec

This is impossible as I was getting very good results before.

I am wondering if I did something wrong, or missed anything.

Just for information, system specs:

Intel i7 2670QM 2.2 GHZ
4 GB RAM
1 GB GeForce GT 520MX
512 MB Intel Graphics

I played 0ad with and without optirun and the performance was good in both of them, but not sure if it switches the video cards itself.

I also have bbswitch installed.

Any help would be appreciated. Thank you.
