Poor performance with uncontrolled aircarft

[Shadow KT]

I have a mission, I started working on a long time ago and it used to perform well, but now as I am revisiting it, the performance is horrendous. Not only on my machine, bad performance and stuttering on my machines, when hosting, on a powerful dedicated server as well and on other clients which have good performance normally.

 

You can see that CPU and GPU utilization drops down to 50% and stutters happen. If you pause the mission, utilization goes back to normal and performance as well, but if unpaused it drops.

 

Mission just has a bunch of uncontrolled aircraft. I've had missions with a lot more AI, which are actually active and there has been no performance issues.
