Low GPU/CPU usage and Performance Impact with traffic

Hello guys, Beam Ng is running on very low GPU/CPU usage when using traffic and fps drops down to around 40-50FPS, without traffic the game is running pretty fine.
I am playing with maxed out settings.
I have an RTX 3060TI with an AMD Ryzen 5 3600 boosted to 4,2GHz and 16G Ram.
In fact that this isn't a low end PC Ian a bit confused if there is a problem with the game optimisation ore if my settings can't handle KI traffic in beam Ng.

Has anyone an Idee what can be the problem?

 

Overheating possibly

 

P_enta, the system isn't overheating at all, it's on 60 degree CPU und 65 degree GPU.

 

How many cars are you running? It’s not super optimized

 

The spawn rate is on auto, I think it's maybe 7-9 cars ire something

 

Then that’s typical frame rate for your setup. BeamNG is very taxing.

The cpu usage looks low because it’s an average of all thread utilization. The threads beamng is using are maxed out, whereas the others are somewhere between 0 and 50 most likely.
Please correct me if I’m wrong
