Found out exactly what this does in the sim. If I disable it (value of 0) then you lose the nice grass textured polygons around all the airports and taxiways! Personally I had never seen this stated anywhere and thought some might like to know about it. I was working with some new mesh and noticed I had done this by accident doing some tweaking. Thought it was worth posting about!Hornit

I've always had it on.What was the reason for disabling it in the first place? Performance??James

Was just messing around with my cfg and meant to turn off the TERRAIN_USE_VECTOR_OBJECT and not this one, did it by mistake. And yes it was for performance :)Hornit

Any improvement in performance ?
