Hello barrybaldy
Can you confirm you notice this in P3dv3 with flyinside ( just to be sure we are talking of the same thing)
Strange ? Did you made something special ??
Other people in avsim forum notice that now there is spinning clouds with flyinside but no more in native p3d ( after shader cleaning)...so i suspect that new shaders could solve this problem, but not a lot of comment about i hear..
