My all graphics settings are set to high and frame rates are limited to 30 , when I am near the ground the scenery flickers a lot after climbing a little it stops and as much as i remember this did not happen before the update I dont know whether its a bug or it was there from a long time.
look the scenery at a distance flickers a lot and also i have compared it with the latest stream of aviator dan same graphics and i dont see any flicker there.
I don’t see anything abnormal with the scenery, perhaps the added contrast between the different colours on the ground, coupled with a new rendering method gives you the illusion of the ground “flickering”.
