low fps / not playable

Hello fellow Beamng people,

I decided to open my own topic now for my problem as i cant find a solution.
Since 0.8 the game is not playable for me.
At first, i thought it is the nvidia card which isnt used so it would lag a lot.
But i found out it must have something to do with the cpu, as my changes in graphic settings doesnt change anything at all.(nvidia as global gpu ...) On lowest settings 12fps on highest 12fps.
But as soon as i turn on slowmotion my fps goes UP
8 times slower is >30 fps for example.

Does anyone else have a similar problem?
Can anyone help me with it?
Thanks for taking your time to read this.

UPDATE:
Disable vehicle collision in gameplay settings helped me.
I have >50fps now. But its not as before. i never needed to turn this setting off.

I use windows 10 on a msi GT70 2PE Dominator Pro Laptop with gtx 880M
I clean installed the game. (erased Beamng folder in mygames)
and safe starting it.

 

UPDATE 2:
Iam continuing my posts and research in this topic:

Could you use a tool such as hwmonitor to confirm temperatures while experiencing lag? And also ensure you are on charge and windows is running the high performance power plan

 

Ok im going to make Screenshots of everything tonight. Power Plan,nvidia settings,cpu heat? Thats all you need?
