why are high level clouds so fps heavy ? I can fly through all weather below 30k fett without issues, but some high level clouds at 37k feet, my gpu just goes to 100% and gets wrecked, fps down to the 20s.
out of the clouds again, fps comes back and gpu back to 60ish %. Also issue might be mistaken with fps degration over time, as there are high level clouds quite often over the ocean.
I have noticed the same FPS drop when in clouds similar to your screenshot. Iām not sure if it has to do with altitude as Iāve experienced it down low rarely but only in that cloud type. I am no meteorologist so forgive me for butchering the description but it seems to happen in āflat whispyā cloud layers. Other than those layers it runs beautifully.
Iāve had this problem since day 1, last August. I would love to get a sound explanation about why this happens. Definitely only happens in large layers of āflatā clouds. Maybe this is why they are so reluctant to give us cirrus clouds in the sim.

Yeah. Sometimes when cruising at FL370, I see volumetric fogs.
When our airplane is surrounded by this fog, the FPS will drop drastically.
Very noticeable in VRā¦ Down lower I can fly though cumulus on ultra and it is smooth as butter. When you get higher into the shapeless blob that I would assume are supposed to be cirrus, the fps tanks very noticeably. TBH, other than the cumulus I wish they would redo the clouds. They donāt look that great. Too uniform.
Its not only high altitude clouds. Its just this certain layer/rendering of the clouds that causes Stutters. They can also be as low as 3000ft. Its this Fog-like layer that causes the troubles.
I get this too (and have reported.) Iāve found dropping clouds from Ultra to High helps quite a lot
Exactly - there are certain type of cloud types or ādensitiesā that seem to cause this fps drop, regardless of the altitude. Last had this in Ireland (which is guess is a good place to test clouds and fogā¦).
Here is my seal of approval for this cloud discussion 
yeahā¦ the volumetric fogs at FL300-370 that will kill your FPS when youāre flying inside it. Is Asobo aware of this bug?
Same problem !
Yea true true
Agreed with this. This topic should be moved to a voting area so others can chime in, but yes, itās an issue for sure.
Agreed I have also noticed this many times and also suspect it could be sometimes the reason people claim they have inconsistent performance from one day to the next. If you have live weather you can sometimes get a cloud combination which is brutal for FPS despite looking similar to one which performs well.
I also note the broken clouds preset is quite a bit worse for performance than others eg scattered clouds, although I think all presets have been improved a bit recently.
I found that after the performance update that clouds have a much bigger performance hit than any other setting. Can run everything at Ultra on my 3060ti except clouds. With clouds on Ultra I was getting a significant performance hit near and especially flying in clouds. With the setting on high I get much more consistent performance without the significant cloud hit.
