Whilst SU4 seems to have addressed the see-through cockpit (LOD?) issue that was introduced in SU3, it now seems to have rendered the A350 unusable, in my view.
On my PC (high-end), I am told that all of the batteries are off, one engine’s master switch is off and unsurprisingly, that that engine has low oil pressure.
I don’t think the LOD issue is completely resolved either, since lettering on some of the buttons can disappear either when I zoom out (not excessively) in 2D, or when I move back a little in VR. This seems to apply on all airliners.
