Severe stuttering in clouds

I am using latest official build of ASFS with MSFS 2024. I have all settings at default except for Prevent Downloads on Approach and Departure is True, and am using Weather with Active Sky Preset Sim Depiction. Clone dep/dest weather is true.

What I frequently notice during descent, even on a day with just a few cumulus around is that as I get near the clouds my frames drop by 50-75% and there is severe stuttering and the clouds appear stuttery and sometimes when viewed from say the passenger cabin, they dance up and down at rapid rate.
That eventually passes. My sense is that this may occur during a weather download and it occurs even though I am near to the airport. It does not happen all the time. I have also seen this climbing out in heavier cloud conditions.

This really ruins the immersion.

One time I was approaching Juneau with very low visibility and maybe 15 miles from the airport or more and suddenly all the weather cleared to perfectly clear with unlimited visibility and the quickly resumed the low visibility again.

If this stuttering is due to redrawing the weather during a download, is there a way to minimize or avoid this aberration? Since I have the prevent downloads option True, I would think that these downloads on approach would not be occurring.

I do use FSIPanel to set up practice approaches, and that also allows one to materialize far away on a STAR at high altitude ( Example FL 240)and follow it down. After FSIPanel sets up the scenario, I can clearly see that Active Sky creates the weather locally before I start flying. I have noticed the stuttering with these practice approaches.
I have flown only a couple of full flights with MSFS 2024, so unsure about whether this is an issue with a full flight.

Respectfully, it’s been a month since I posted this, and no reply to date. Not sure what this means. Is Active Sky no longer supported?

Of course it's supported. Sometimes things get missed on forums. Our ticketing system is the best way to ensure a timely response.

ASFS does not inject any significant workload/perf hits, and especially nothing extra when within clouds other than control turbulence. You can rule out turbulence by turning turb scale down to 0, but I don't think this will make any difference. Likely, your sim, settings, or other add-ons are having a hard time in clouds.

We don't redraw weather, btw, it's constantly updating through several processes/threads, there is no "redraw" flush. Weather downloads simply update the source weather data. Other processes update the target weather, and many other processes update to eventually change cloud conditions, mostly uncoupled.

So I'm not sure what's happening here, but would recommend you try MSFS cloud res setting adjustments to see if this changes anything, as well as try with no weather updates by switching to custom weather after a previous normal live or historical session (so nothing downloads/changes). Also check other add-ons that may be interfering or causing load, perhaps trying an isolation test without those add-ons loaded. If this doesn't help, please open a ticket so we can directly troubleshoot with you.
