Classic British Flight Sim

Decided in the end to go down the P3Dv5 road. Very smooth and in the process of loading all my planes in to the sim. I have however noticed I get a white shimmer sometimes on the edges of the planes and scenery edges. Tried all sorts of internal settings but cannot seem to get rid of it. Anybody know what it is and how to sort it please. I have a GTX 2070 and not adjusted settings outside the sim yet.

It's a side effect of the advanced atmospherics. Only solution is to turn it off.
As the atmospherics are still in beta I'm sure it will improve with future updates.

Thanks I will do that and wait.
