Outside scenery is "shaking"

[Bergslagen 0]

Why is the outside scenery shaking like his from inside the VC? https://i.imgur.com/cZ65GNl.gifv

The same happens in an outside aircraft view.

I still have still a problem and some help would be appreciated.

Does the sim exhibit this behaviour with default aircraft and airports? It might be the aircraft doing the shaking, rather than an earthquake . I think it can happen with some PMDG planes depending upon the scenery etc. There are quite a few posts about shaking aircraft, but more details are needed (sim, default or add-on scenery/planes etc)> Hopefully then someone more knowledgeable than myself can help out.

I also thought it could be due to the engine vibration setting, but then I realised that this option probably 'translates' the viewpoint up/down/left/right slightly, but doesn't rotate/pan it. So it would make the cockpit & window frames jostle about relative to the horizon, but it shouldn't make the horizon or distant scenery move about.

I could be wrong, just guessing. There are a lot of sliders so setting each one to zero should easily tell you if CP is the reason or not.
