Hi,First of all, a big thank you for this update. The most impressive thing for me is the enhancement about fps.Just one problem, I've two small hills on short of runway 10, in the axis of the runway (very short final as you can see on the screen), the second one is just a few meters away on the left. I'm using FS Genesis mesh at 38m and parameter Terrain_Max_Vertex_Level set to 21.By removing FS Genesis mesh, the problem is still present but the hills are more flat. By setting TMVL to 19 (default) and removing FS Genesis mesh, the problem is still present. So, if there's a flatten file in the v2 you should extend it a bit to cover this area. http://www.emmanuelparot.fr/preview/oharev2.jpgBest regards,Emmanuel
