High altitude clouds performance

[Axis3600 50]

Hello,

Have you noticed that clouds / mists at very high altitudes (FL330 350 370 ...) completely bug MFS?

I am towards Agadir it is very well done super beautiful I see nothing around the plane but my FPS have dropped from 30 to 15 10 ...

And it returns to normal after passing the high altitude clouds / mists ...

Same here. kills performance. You cannot see much there anyway and If I move my view to the cockpit and obstruct most of the view of the clouds the framerates return

Yes indeed by changing the view I can recover the FPS but as soon as I look in front to the right or to the left in the clouds it buggy.

Which is not the case at lower altitudes than at FL70 5000 '3000' I have no FPS problem.

It's weird

Hope they can fix this on an update

Yes, this is hilarious. These clouds look meh at best, but tank the FPS more than a full blown thunderstorm on ultra settings. I just sit thru that and shake my head.

Clouds have not affected my FPS as badly as I was expecting.  I seem to gain very little turning them down so have kept at ultra.  I do tend to not have too many layers though or only one layer of overcast.

I guess these are suppose to be high altitude cirrus but they never got those cloud types right.

That's right Den.  Asobo know they are not right, and they said they might look at doing proper cirrus / cirrus patterns at a later stage.  Another one for the backlog I suppose.

Apparently, the new clouds aren't textures, but generated particles.  So programming wise, it is probably easy to get them to 'clump' into a puffy cloud such as cirrus cumulus, but not so easy to get them to generate cirrus / herring bone type patterns.

Here is when I pass in a layer like that, I lose 15 FPS ...

Would suggest voting this thread up and submitting tickets on how to reproduce (have done that as well).

I wonder if some ground fog does the same thing

You can get this performance drop with low-level layers as well. Believe depiction using a similar cloud/fog layer type is what is causing the drop. And @Colonel X - exactly. Other high-density cloud depictions such as thunderstorms don't seem to have the same hit.

Whilst clouds have an impact, high level traffic settings cause me greater problems.  Road traffic particularly but airport traffic when at or around airports too, especially the busier ones.

No, I landed on an airport with fog and little visibility, it didn't take FPS like high altitude clouds.

I have no FPS concerns with road traffic.

It's a little off topic but it's weird also I tested road traffic at 0 and at 100% it takes very few resources compared to P3D or it was a killer of FPS!

So I don't know how their road traffic works but it's not bad
