Nixi

I had same problem when indoors turning towards city center cut my frames in half,and I've noticed my occlusion was turning off because some error with async readback or something like that. I've tried switching to opengl and vulkan but fixed it finaly when I've disabled new dynamic mesh feature.

Looks like occlusion is not working. Also tweaking new distant terrain settings seems to help but massive fps loss in big cities. Especialy indoors fps depends which way you are facing.
