Multicore rendering not working

Multicore rendering not working csgo Linux

Hi,

First, sorry for my bad english, i'm french.
I have a problem with the game csgo.
One of my core is always at 100% of use.
I tried the option -thread 4, but this dont work.
I also tried with other game like "half-life 2" and it's work perfectly.
So the probleme come from csgo... I tried to desactive "multicore rendering" in csgo options, but nothing change.
Please help me.

I have the driver Bumblebee because i have two graphic card, one Intel, and one Nvidia.

The problem with my core at 100% is present with the two graphic card. If i start Steam with Intel card or Nvidia card, it's the same... the core is at 100%

If you need other information to solve the problem, ask to me and i will respond the most quickly.
