Did you also post this on AVSIM? I may have responded to you there earlier. Here is the existing thread for the terrain morphing, your video would be a good contribution there!
Brief description of the issue:
Doing flights over mountainous terrain, eg. between Innsbruck and Zurich, the mountains are continually popping and changing shape - others have described it as “morphing”. This came into existance after the USA update and has persisted through the UK and now the Nordics update, with the Nordics being the most noticeable and worst. This effect is very off putting as even if you try to ignore it, your eye is drawn to each mountain as it pops into a different shape…
About the photogrammetry, this might be more relevant.
I did a search in Bugs & Issues and didn’t see many “votes” on this issue, so if there is a previous bug submitted that people are voting on, please move my message (mods).
I feel Photogrammetry has gotten worse since Patch 2. I am not a developer, don’t pretend to be, but I am a consumer who loves this sim and wants it to be the best it can be… and right now, photogrammetry and LOD have caused me to lose faith. The sim isn’t as beautiful as it was marketed, nor has it gotten better as patches …
