ASFS beta 9106

Anyone else having an issue flying on dense clouds ?

So i just completed a flight in the 777W from sydney to auckland

Descending to nzaa between 280 to 210 i was getting fps drops and stutters.

Then stopped and then at 9000ft.

Then it was smooth sailing till i landed.

Using autofps

And passive mode 

Thought this issue would have been fixed.

Which was mentioned on their forums about high cirrus clouds ?
