Clouds on ultra = stutter? why exactly?

[ThomseN_inc 1,128]

Good day everyone and a happy new year!

 

With Clouds set to ultra I am seeing the mentioned issue especially flying through high altitude clouds or sometimes when looking outside the side windows at certain angles. 

So for example i am cruising at FL330 and i am entering a layer of high clouds the sim starts to stutter when i pan to the left (or right; seems to be random) and as soon as i reser the view forward its smooth again.

Also the "amount" of cloud does not matter as a small single Cu can have the same effect as a thick layer.

Has anyone else oberved this and/or a clue on what might be causing this?

 

Specs:

i9-9900k@5.1, 32GB RAM, RTX3080 Sim@30Hz

 

Best regards,

Tom

Hello Thomsen.  I had this as well.  I think it is just the usual performance issues as you turn everything up.  We are all waiting for the DX12 switch-over to solve issues like this, and it should help.  Whether they hit the deadline of Summer 2021 or not, I don't know.

I just use the high cloud setting now instead.  I know it is subjective, but I find high clouds look better anyway.  To me, the ultra clouds look too lumpy and not realistic at all.

By the way, the slight stutter when panning sideways is a general issue; I get it a bit when flying low and looking at the landscape going by also.

PS.  Relating to your 3080, even the best of cards won't cope with a poorly optimised sim or DX11 performance issues, but I also think our expectations are still too high sometimes.  Roll on DX12.  Will it be the Holy Grail?  It might be half a Grail I think!

To be honest clouds on high does look better to me too. I was just wondering since i only have this issue occasionally.

I get that little stutter too especially during taxi. Even @30Hz. All in all the performance is great now that i got used to the 30Hz setup and i can't complain really. 😛

Yes I am fairly happy with my settings / performance balance now.  It the main, I get slight stutters when I am approaching complex airports, and when turning the aircraft during taxi.  There is also a common one due to the glass panels I have noticed - as you say, straight ahead view is fine, but when you pan your head and it takes in a glass panel and the outside view through a side window, this can stutter sometimes. 

Like I say, you have a fantastic card there (3080), but with some of the 'characteristics' of the sim, there is only so much it can do.  My bet is that without further graphics optimisations, even the follow-on 40xx series cards (rumoured to be 60% faster) will still show this effect to some degree.

I find high clouds settings look better also, and it save me some fps that I need att busy airports.

You need to understand that clouds in MSFS 2020 are not polygons with textures anymore, as in every previous simulator.

Instead they are generated on the GPU in shader code, which can be extremely demanding even for the best cards.

I use Ultra and have no stutters at all.

I also use TrackIR and no matter how fast I look from left wing to right wing or any where I never have any stutters. Sorry!

I suspect you are seeing stutters because you are CPU limited, what are your other settings Inc resolution?

Yeah I have a 1080ti and I’m not getting stutters on Ultra... and here I was bummed I could not find a 3080!

The 3080/3090 will stutter unless you push them harder. You need to be gpu limited all the time, otherwise you’ll get stutters. Push the gpu harder. Make sure you’re gpu limited.
