Sorry to hear you all of a sudden decided that SkyMAXX was no good, are we speaking of small pauses in the simulator or abrupt changes in the cloud conditions? If you are having pauses in the simulation, there may be a hardware missmatch on your system. I suggest trying to adjust your rendering settings for best performance in X-Plane. Additionally you can tweak SkyMAXX for better performance, a couple of big hits are the crupuscular rays and the cloud reflections......SkyMAXX is waaaaaaayyyyyy more frame-rate friendly over default..... If you are speaking of when you fly through cloud layers how the clouds transition, this is a feature in SkyMAXX, like it or not. We decided to de-activate "the grey screen of death" in favor of letting the new clouds dictate visibility, we have no plans on bringing this feature back since the vast majority of users were keen on this happening... -John
