I’m finding performance very good in 4.5 with heaps of AI traffic. No texture flashing and the night lighting is perfect although I’m not a big fan of dynamic lighting because of the way it lights up the whole flight deck. (Like to be able to turn DL off) I’ve noticed there’s some road traffic that doesn’t go under the taxiway but rather climbs vertically up then drives over the taxiway then down. I have not had time to read the manual yet but so far I can’t get the air bridges to work
