Bumblebee slow performence

Chef_Keeper · 2017-01-09 21:06:45

Hello,

Having a laptop with 2 GPU : 1 intel and 1 nvidia geforce 750M I installed bumblebee to be able to use the nvidia GPU.
However even if it seems to work glxinfo showing intel by default and Nvidia with oprirun, I get aproximately the same performence...
Tryed with unigine, and few games.
glxgears even got better perf ~10k FPS with intel and 700 with optirun...

I followed all steps from the wiki : https://wiki.archlinux.org/index.php/bumblebee

PS: If someone could explain me why we have to install mesa ? I thought the nvidia drivers where supposed to implement the opengl specs

Cheers,
Chef_Keeper

I have a similar setup, but the only difference is that I use Primus instead of Optirun. For reference, I got a Lenovo Y510P with a 755M.
I also use 'vblank_mode=0 primusrun $command' to launch programs that I want to render with the GPU.

Notes:
- It may be a Composite Manager problem? (Like compton, etc)
- Always test with the notebook plugged in.
- Try some official game launchers like Steam (For native libraries, etc)

You should also post your

/etc/bumblebee/bumblebee.conf

.

Hello,

Thanks for you input, I'm using LXDE with openbox as composite manager, what do you use ?
I tested with laptop plugged and unplugged several times it doesn't change anything (I didn't install any power management tools yet).
And I tested with many different programs like stream games : dota 2, torchlight 2, but also opensource games like openMW and result is similar with every game I got nearly as much FPS with optirun than without (or like 1FPS gain^^)

My bumblebee conf (I never changed anything, so it's all default) :

# Configuration file for Bumblebee. Values should **not** be put between quotes

## Server options. Any change made in this section will need a server restart
# to take effect.
[bumblebeed]

# for X to be ready is too long and don't need power management at all.

ServerGroup=bumblebee
# Card power state at exit. Set to false if the card shoud be ON when Bumblebee

Oh and I tryed to install PRIME yesterday following the wiki : https://wiki.archlinux.org/index.php/PR … t_provider, but I had a problem with

xrandr --listproviders

not showing my nvidia

Have you tried primusrun? Have you multilib enabled, all the required lib32 packages and lib32-primus installed? You can test if optirun gets better results when changing bridge from auto to primus.

I did enable multilib, and everything works fine with optirun except the poor performance.
I tried to install primus with open source driver following the wiki : https://wiki.archlinux.org/index.php/PRIME but when I do even after reboot I only got 1 provideo with xrandr --listproviders
Maybee I should install the proprietary drivers ?

You are mistaken. Primus != Prime. You should set up bumblebee correctly first and then if you are unhappy with the results jump to the next method like prime . I would not use nouveau if bad performance is what annoys you. Read Bumblebee again, especially on how to setup primusrun. I only use primusrun in steam (eg dota2) if I use bumblebee on my gtx660m notebook and the results are quite good (Better than optirun for sure).

Thanks for the tip, I actually mistook primus and prime !

So I installed primus for bumblebee and it did improve my FPS quite a bit around 15 more in the few games I tested like dota 2.
Problem is that it also "only" improved by 15 FPS for openMW having ~45 now on linux, but I tested it on windows with vsync off and got ~200FPS.
I'm fine with the fact that I loose a few FPS on linux but not 150

And I instaled the nvidia drivers.

Should I try prime now ?
