Hi!
It's good to hear, that the area of clouds will be bigger.
But much more of importance is, that the redrawing of the refreshed weather will not result into very strong FPS decreases anymore.
I use the a high performance rig (see below) and used to have the settings listed below in XP10.51 which gave me an average of approx. 40-60 FPS.
But always, when the METAR file has been changed by FS Global Real Weather the FPS dropped down to a single digit of 1-9 FPS for seconds.
This is not acceptable and I uninstalled SMP 3.1 by now. There is a need, to solve that. Probably by redrawing the new weather step by step and not in one big run.
My rig:
Win 10 (64bit), Intel Core i7 6700K@4.6 GHz, Overclocked NVIDIA GeForce GTX 1080, 32GB RAM, 1.25 TB SSD, SAMSUNG SUHD 55'' TV@3840x2160
My settings I used in XP10.51:
