I reinstalled the game several times and removes mod but it does not work better

 

What are your computer specs, CPU, GPU, RAM?

Also can you post screenshot of your graphics settings?

 

cpu=i5 gpu ,gtx 970m 3032mb and ram 16gb

 

Ok, that sounds like a laptop, it is possible that your laptop just does not have enough computing power to run so many cars, especially if using high graphics with ssao and dynamic reflections on.

Generally 1 car for 1 physical core is what can be done without slowing down, with recent improvements to game, it can get close to 1 car for each thread of CPU, however CPU graphics will still limit, especially slower CPUs, like those on laptops etc.

Not sure which i5 model your CPU is, but it can be bit weak for more than 2 cars on full graphics, even your GPU might be capable of rendering more.

This game calculates hundreds of physics objects 2000 times each second, which is far more complex than anything else out there.

 

ok thanks for helping me

i have a i5-6300hq 2.30GHz

 

Ok, that should be good for 2 cars maximum and no dynamic reflections or ssao, also keep shadows at partial or off.

Also ETK K-series might be too hard for that CPU as well as Italy map.

If you see this, you can see your CPU compared to Ryzen 1600:

Then in these graphs you can see how Ryzen 1600 handles bananabench, it might help to see what CPU can do:

Your CPU has very weak single core performance, but also multicore performance is about same as i3-6100 desktop model which I had (still have actually). i3-6100 was good for 2 cars and with 3 it started to slow down a lot, with your weaker single core performance there just is not enough computing power with your CPU for 3 cars.

With laptops there are also powerlimits that can reduce performance after some time, so benchmark might show higher performance than there is in practice.
