Extreme FPS loss at Dover Castle

[Schlomo1933]

Dcs MT VR: If I fly with the Apache to the castle in Dover the Fps will drop from 60 to 5 .

It start happening a half mile in front of the castle. (I can hear that the fans of my gpu are slowing down to idle)

After overflying the castle or turn around the fps gets back to normal and the fans throttling up again

I've encountered the same issue recently. Flying around the castle causes extreme stutters.

Track file attached. Video demonstration here:

I've got 5060 Ti 16GB in PCIe 3.0, that's true, but the FPS drop is massive compared to the reasonable FPS before. Something fishy is definitely going on there in that spooky castle.

One more observation - when the simulation time is slowed down (1/2, 1/4)... the FPS drop is not that massive. It seems like DCS is very quickly loading something or what (wild guess), because the FPS is not caused by the scene itself, but by the fact we pass around very quickly.

I made one more (shorter) video - and with DCS stats. Even though the Afterburner doesn't show anything suspicious on the CPU, DCS stats show clearly that that area is CPU bound.

This is not a speciality of Dover castle only, I found similar stuff on other maps and with other buildings - so it seems there is something about some buildings that cause a massive problem. But I don't want to diverge here.
