Extreme frame drops when traffic feature is enabled

My pc is capable of running well over 60FPS with traffic on auto spawn mode. This was the case prior to the 0.18 update. When running the game with at least 3 vehicles the game drops to 10-15 fps. No mods or special game configurations.

My specs:
Cpu: Ryzen 1700
GPU GTX 1060
Ram 16GB ddr4
SSHD 1 TB 2700mbs

 

yeh same lol i have just made a post how the game was also using way to much ram 24gb is to much

 

I spawned 3 vehicles manually (east coast usa) and the game had poor fps but not as bad as traffic. I'm assuming this is because of buses and the T series spawning but I have noticed on Utah that driving with 1 vehicle the game has hiccups and freezes momentarily every few seconds making the game difficult to play. This is with no mods installed either.
