Yes, it's slightly odd seeing the clouds appear/disappear (even when stationary - just rotating the view seems to cause the problem). However, the overall effect is fantastic - is there any way to see the precipitation model yet?
Great work Harald!

Clouds are not culled correctly. That explains the poping, but it had also an enormous impact on fps.
In attachment is a quick hack.
