Question / Help Stuttering at 60fps

[Stream Advisor]

Hello!
I have low fps on stream ( 35 - 48 fps ) with obs Studio and Streamlabs obs
In-game i have like 250 fps ( Rocket league )
My setup :

CPU > i7-8700K
GPU > RTX 2070
RAM > 32 GB

My Cpu reaches a maximum of 70 Celcius ( Overclocked & Watercooled )
My Gpu reaches a maximum of 60 Celcius
This is while playing the game and recording / streaming at the same time.
I should have no trouble streaming at least 720p 60fps maybe even 1080p 60fps.
My bitrate = 6000 ( Speedtest > 250 mb down 20 mb up )
And all of the other stuff doasnt really matter because i have tried them all and it didn't change a thing with the FPS.
Still the same ( Choppy / Low fps )
Yes the quality changed sometimes when i set the cpu preset higher or lower but that didnt really matter with the fps of the stream.
I don't think its OBS or Streamlabsobs because i have tried them both with the same results.
So i think it might be outside of obs.
Maybe software interfering or whatever is out there in the background.

A log file would be pretty mutch useless when the problem is not within obs.
Do you guys have any ideas what it could be?

Thank you for all the help you can give me!

Have you tried limiting your in-game framerate, since OBS still needs about 5% GPU headroom?
Maxing out your GPU is bad while streaming, unless you run a dual-PC setup, that isn't an NDI based setup.

Thanks for the tip @Zidakuh ! Yes i have tried that yesterday and it worked! 250 fps in rocket league seemed a little to mutch. now running on 144 fps and looking really smooth!
