What's the difference between mesh complexity and mesh resolution?

I may be wrongBut I beleive mesh complexity is the actually complexity of the terrain (i.e land/mountans/valleys etc)and mesh resolution, is the resolution of the ground textures.but then if I am correct... then what is the "texture resolution" for?I would like this clarified also :D

i know mesh resolution is the "accuracy" of the mesh... for example, more curvature due to tighter defining points...

Hi guys,the mesh resolution slider forces the sim to use a specific grid spacing in its display (in FS9 this was the Terrain_Max_Vertex_Level defined in the FS9.cfg file). Thus, at 1 meter FSX will compute the terrain mesh (not the textures draped onto it!) as a 1-m grid, at setting 38 with a 38-m grid etc. Two things to keep in mind: this setting is independent of the terrain mesh files (default or add-on) you may be using, that is you can force the sim into a 1-m grid even if your best mesh is at 76-m resolution, and vice versa. Further, FS automatically switches to lower resolutions with increasing distance from the user's airplane; think of it as concentric circles of decreasing resolution similar to the mipmaps in textures. On the other hand the "mesh complexity" slider works directly on the terrain mesh data in that it influences the amount of detail (e.g., peaks and valleys) the mesh will show, at all distances.I must admit I'm not sure how the mesh complexity settings are achieved in relation to the underlying grid but it's probably some kind of interpolation that reads fewer of the elevation points in the mesh file with a decreasing mesh complexity setting.Maybe somebody else knows more about mesh complexity!?!Cheers, Holger

that makes sense... still not totally understanding complexity... but everything else you said makes sense... sounds good by me :)

So, same question as for FS9. Which is better for accuracy and/or framerates:38m mesh at 50% accuracyor76m at 100%And what happens when you try extrme variations - does 10m at 10% give 100m effective resolution, or just crappy scenery? :)Allcott
