Hehe, maybe now that I said it the sim will disprove me (Murphy's Laws always linger). Maybe this is
all a coincidence... that is lasting 5 sim-days.
And I had barely finished to say that... ¬_¬"
I'm not privy of AF's weather details, but if I were to make an educated guess I would infer that
'set g_bEnableWindsAloft 1' somehow makes it unlikely for the wind to 'push out' all the clouds
before the weather system manages to elaborate on new ones to insert into the theatre. And this would
be, 'cause the wind is not allowed (with the switch On) to blow into the same direction for too many
sim-hours.
That 'unlikely' is the problem. It's just an 'unlikely'.
The fact it's unlikely isn't enough to guarantee it'll last. I should have known.
No more clouds. This is 8 sim-hours after the last screenshot:
(am I disappointed...)





Here's where they have gone (I think).

My route later brought me closer to them. I believe to have recognized the same cumulus formations
observed around my home plate only 8 hours earlier. But here is at ~130 nm away from home plate.
This is enough to disprove me (gee, thanks so much...).
The 'set g_bEnableWindsAloft 1' switch certainly has some effect on the clouds (it's no coincidence
that they lasted 5 good days), but it isn't enough to prevent the theatre from turning almost cloudless
in less than half a day. At best it makes it harder to happen.
Looks like periodic clouds injections are still needed to keep the sky interesting. Less frequent injections
than without 'set g_bEnableWindsAloft 1', perhaps, but still needed.
I perfectly understand that the real sky is rarely as full of clouds as I'd like. If I look out of my window
right now there's no clouds. It's the same white-azure gradient filling the sky in all directions as far as
my eyes can see.
But the real life terrain is rich of features. With or without clouds a pilot has constant perception of
movement and speed. In AF the terrain is less feature-rich, and clouds are useful, even
necessary, to
some extent, to provide the simmer multiple points of reference, so he retains perception of movement
and speed.
I wonder what your FPS numbers reflect with the newer weather 'conditions'
My hardware (which is far from exceptional for today's standards) appears to have enough excess power
to keep up with the workload, no matter
whatever about clouds. Nevertheless, I'm trading a lot for all
the pretty clouds I showed in the past days. Do not think they come for free

Nothing does.
But since I Vsync AF with my monitor refresh rate, I'm not seeing any performance difference both with
and without clouds. But I'm sure the difference would show up if I turned the Vsync off. It's normal.
The cumulus clouds appear to be the costly ones. Just like all clouds, they cast a shadow on the ground.
The CPU has to work in order to compute *where* the shadows will appear. But the cumuli clouds also
have a 'translucency', which has a cost for the GPU. Little cost, to be sure, but when you put like 400
translucent textures all together and overlapping with one another, then the GPU workload sums up to
something you can't ignore (more so when all nVidia control panel graphics settings are pumped up to
the maximum, as in my case). Still, AF handles the situation very well. I've seen more modern games
cough their soul outta the rear end when asked to perform a comparable feat (and without me messing with
the control panel settings).
