P3D2.3 and ASN Huge FPS drop

From what I understand was the performance improvement for P3D2.3 in the first place aimed at better performance with weather engines and from what I read would the ASN update also improve performance, so I'm a little confused to see that when I turned on ASN with the same settings as in P3D2.2(just 2 cloud layers, draw distance of 80) my FPS dropped by more than 20FPS, while in 2.2 that was only a drop of 10FPS with comparable weather (just cloudy, no rain, no storm).

Wasnt the whole idea behind the updates to be able to use more cloud layers, a better draw distance and be able to turn cloud shadows on? I've got 10-14FPS left, while in 2.2 I still could count on 20-25FPS.

I also notice that when I set my cloud draw distance to 80 in ASN, it pushes my cloud draw distance in P3D back to 70 and with cloud draw distance 70 in ASN, the cloud draw distance in P3D is pushed back to 60.

Anyone who can shed some light on this?
