How to deal the poor bumblebee performance?

Question

I'm using Archlinux, kernel 4.12, bumblebee 3.2.1, nvidia driver 382.

When I run the optirun glxgears and vblank_mode=0 primusrun glxgears, the max FPS is near 3400.

But when I run the glxgears directly with NVIDIA Driver, the max FPS is near 20000.

I don't know what's wrong. Is there better solution than bumblebee or some way to deal this problem?

Answer 1

I am using this optimus technology with archlinux for two years now. The only way to get max performance (for now) is to use vblank_mode=0 optirun -b primus . There is no other way to get a better performance for now!
