KLAX VRAM and online traffic

[MD82]

Hello, 

this is more of a question rather than any bug. I run 4K and KLAX together with Los Angeles is really taxing on VRAM. For some reason I don't yet understand, online traffic disappears when I am in LAX. Especially when it's busy.

My question is, does anyone know what setting controls this? Is it a general MSFS thing limiting objects? Or can this be controlled in MSFS or vPilot? I tried dynamically lowering LOD's, but traffic refuses to show and as such I'm all alone in an otherwise busy LAX with VRAM around 85-90%.

Thanks,
