The A350 Cockpit remains extremely laggy,and i think there is another problem Different from "device performance" as mentioned.
I did the tests, in all other aircraft I can get above 30 FPS with everything in Ultra, aircraft light on and 100% resolution.
But On the A350 it continues at 5-10 fps, even with everything on Low, and I discovered that this only happens at night, on the same A350 I consider good performance even with Aicraft Lights on if it is daytime,We need to give attention to this.
I'm also having this same problem. When the A350 has its lights on at night, the drop in frame rate is considerable, dropping to less than 10 FPS. This appears to be an optimization flaw as it only occurs with the A350 and not with other aircraft.
