Flickering cockpit/dashboard/panel lights happen after looking around.
I’m using TrackIR and when looking around (moving my view around using TrackIR) the cockpit, dashboard and panel lights start flickering really bad. Switching to external view and back fixes it until the next time it happens. In the video the first time it happens is right after I looked down at my throttle controls. Switching to external view and back fixes it. The second time it happens is from just looking around. I then show my graphics settings including Terrain per-chaching being set to Ultra.
I am able to reproduce in the A320NX Superjet100 and the headwind a330 so since i am able to reproduce with all does aircraft i am made to believe that is a bug from the su6 and not the aircraft it self my logo lights taxi and landing lights flicker alot
Flyinside posted a patch in their forums that fixed it in the Bell 47G for me. I expect it to be in their next update. It may be something that affects some addon aircraft, but the Bell is all I noticed it in so far (don’t have the aircraft you listed).
Since it doesn’t seem to affect any of the stock aircraft, it may be an issue the addon makers have to take up with their individual aircraft. As it’s a addon problem and not a MSFS problem, I’m going to set this as the solution.
