that what I mentioned and the reason why I can allways reproduce the lower fps around this area with the a320n and why I can avoid that if I use another airplane which use less cpu. Therefore we can also see the same lower fps near ground at ENEV, where I mentioned the LOD setting. I can nowhere see a timeing factor ( my tLOD is currently 230 ).
Why the ground region have a seemingly high effect of fps also in case we fly at >25ft is may be because of that allways the same amount of data are loaded, but don’t know.
PS: there is a wish topic for a dynamic LOD …
