Something is weird with my setup when using traffic mode

Hi there. Not long ago I've started experiencing unpleasant lags and FPS drops while using traffic mode. Sonmehow, the FPS drops to 30-40 FPS in any graphics mode. On "gameplay" menu traffic amount is set to "auto", and normally the game spawns approx 10 additional cars, and then lags begin.

What's weird - the performance graph states that possble bottlenecks are CPU and GameEngine at the same time, but, in that time CPU is loaded not more than 35-40%, and the GPU is loaded only for 70-80%.

Well, and, my specs:

1. CPU: Intel Xeon E5-2680 V2 10c/20t 3.1 gHz.
2. GPU: Gigabyte extreme GTX 1060 6gb
3. RAM: DDR III 1866 mHz 32 gb quad-channel
4. OS: Windows 10 22H2
5. Game is installed on SATA SSD
6. Game is purchased through Steam

P.S.: What's really weird is that I have another PC with I5- 8300H and 1050 4G (laptop), and only 3 traffic cars (4 cars in general) make the CPU to burst into constant 100% load, I have exactly the same 35 FPS, but performance graph states that there are only one bottleneck - the GPU itself. I5-8300H is like two times slower than a E5-2680v2, but has more instructions sets. I don't think, it's the CPU trouble.

Anyone has similar problem, or have the solution? I'll be extremely thankful to anyone, who replies.

 

Yes, i do
Those freezes are occuring a bit rarely in the safe mode.

Besides that, only one car, or 4+ cars without any AI mode enabled are handled well without any perfomance issues
