Title: Plane wing twitch *GSX not the cause*
Post by: tnorton776 on February 16, 2012, 10:53:07 pm
I notice in my turbo prop and Jet aircraft that when im in over the wing view that the wings are twitching rapidly up and down at the wing tips and it seems to be getting progressively worse....  I notice the twitching real bad with planes that have wing flex. The twitching is very annoying and looks awful. -_-

Update: I also notice my planes tend to hop 3 times when switching views -this only seems to occur at FSDT addon airports-. they still did not do this before I installed GSX. Did GSX modify some taxi way contact points?

Update: the shake/twitch appears to have nothing to do with views or camera because when i use the external stationary tower view and zoom in, I can see the planes wing tips jittering. Perhaps something in GSX or whatever has changed a contact point/wing flex/engine power setting inside fsx? I have 720p videos of flights from before installing gsx and the issue is not occuring in those videos.

I really want to avoid having to reinstall everything, because thats a nightmare. Could GSX have altered some settings that may be causing this? It looks awful and I really need this issue fixed.. I know others are experiecing it cause I was in contact with PMDG support and they notice the issue too but dont have an answer at this time.

The only thing for SURE, is that what you see can't possibly related in any way to GSX. The one and ONLY changes GSX does to FSX configuration are:

- It enables the Service door on the default 737 and 747, because the original aircraft.cfg from Microsoft only had 2 exits and no service doors, even if the model had all the animations

- It disables the default pushback vehicle, but that's just a visual model change, it won't affect anything else and, in fact, default Pushback will still work, just with an invisible truck.

Wing flexing is controlled by bones attached to the wings and controlled by a variable, either custom or default. FSX disable animations controlled by a variable after a certain distance to save fps, and/or the airplane might do it on purpose to animate only the highest (closest) LODs to save fps too. So it's just normal that zooming in triggers a different LOD and re-enable animations, so the animated parts will suddenly start to move.

Nothing related to GSX, of course. Its only "fault" is that, by its very nature, you will tend to look your airplane more closely than usual, so you might be mislead thinking that something you never noticed only appeared after installing GSX.

If that is true, it is still a very annoying problem, is there any known fix for this? I just did a fresh reinstall of FSX and non of the planes do this with a fresh install. Something must be getting corrupted with all the combined addons...

I'm thinking the shaking has to do with the way FSX models turbine aircraft, any ideas? When I shut down the jet crafts the shaking stops, when I power up the engines the shaking resumes.

Do any addons make changes to those parameters regarding the way FSX models turbine aircraft?

Hit F1 to make sure your engines are at complete idle.  See what happens.

yes F1 temporarily solves the problem, but its a very pesky problem, and obviously to fly, you cant have your engines at full idle lol. so no one knows of a fix?
