No, no. I have explain badly (spanish, bad english speaker ).

I have test on todays race, Pau67. When I go to the track without moving the car I have 165-166fps with 1 core.
If I activate all cores its the same, 165fps.

When I had the intel 2600k I remember testing single core in a track, it was 80fps, and then it increased to 160 with 4 cores, but didnt rise the fps at more than 4 (5,6,...) so, at least for the fps it seems 4 cores is the max.

I'll test the loading times with single or multicore (prepare targa florio.. )

Ok, you definitely have Vertical Sync on.
My system:
- i7-6700K @ 4.6Ghz (4 real cores, 8 logical ones.)
- nVidia GTX 1070 (no overclock)
- GTL Video Setup / GTL Config:

- In game graphics setting: everything full.
- Track: Altbierbude's download section Pau67.
- Mode Private Practice with Original Mini, just engine started in pits.

My results:
- 1 core: ~185 fps.
- 2 cores: ~432 fps.
- 4 cores: ~530 fps.
- 6 cores: ~520 fps.
- 8 cores: ~520 fps.

If I check the Use Vertical Sync from GTL Video Setup, I get 60 fps with any number of cores as my LCD has refresh rate of 60 Hz. So make sure that you have unchecked it.

Interesting enough, at least in my system the optimum is actually all the physical cores. If you enable the hyperthreading ones as well, you lose performance. Not really sure if it really makes any difference. Pau67 is not that heavy track as the system is able to redraw the frames 4-5 times in a time which the screen refreshes.

However it is true what Dikl said that screen refresh is connected to how often the controller is read, so you do get better response.
