Just after the takeoff from EDDH or EDDF or any near airport on A350 framerate drops to 1-2 FPS and then never comes back to normal. I`ve tried to move Aerofly from HDD to SSD, because I firsty thought it could be the reason, but eventually it is not.
So I`ve also tried taking off from much more distant airports like LFPG or LEMD and nothing similar happens there, everything runs smooth. This happens only with A350 in this particular area (not the whole Germany), all is okay when flying other planes in any area. I play on PC and have Global Scenery turned on, all on ultra.
