I have the same device and it is not ultra but I get 20 to 30 fps with Vulkan on high settings with the resolution at 100% and the aircraft lights off. Of course this is only for the A350, I can get higher fps on other aircraft but I recommend that ultra is not suitable for our device, even medium settings would be more reasonable
What about A320 ? What settings should I keep ? ( I want aircraft lights on and 3d buildings too)
