Weather degradation

And render it visually realistically in 3D, and have it affect your pretend aircraft in a “realistic” way as you fly thought it! Their supercomputers don’t even go that far. Their frame rate of the top view 2D result is like 1fps and it moves in chunks :smiley:

I believe a core group of users exists within this forum and elsewhere assigned with the primary duty to deflect and befuddle with immunity. there is no convincing microsoft unless the idea originates with them or aligns with their interests. you dont keep silent for so long unless things are proceeding as planned.

no clue why people are getting heated over graphics improvements, you can always turn down your settings.
but you can’t go beyond ultra with a downgrade :wink:

RT is confirmed by sebastian tho, we’ll see what that does to the lighting of the sim.

xbox x is the platform of choice and must have the best graphics. pcs have more options but not easy to tell the difference when ultra has been downgraded. they cant allow pcs to go back to the quality of su4 until a new console with enough power is released

I would like to hear an explanation of the weather that got worse from the devs. I know that the cloudbanding appeard in su5. Then in su7 the weather started to be generic and feel same all over the world and the seamless weather were a thing of the past. The last degradation were the worst degradation in my opinion. And they said they added the METAR data for visuals of weather in su7 and i will allways blame that to be the issue. Because that were what they mentioned were the big overhaul of weather in su7.

the weather system was previously working well and provided relatively accurate information, meteoblue that is.
some people voiced their concerns over small discrepancies in wind speeds and cloud formations, and they pretty much got forced to blend METAR reports into live weather.
We had instant weather changes, clouds popping out and in out of nowhere, winds suddenly changing directions.
Now the weather is visually changing 500ms at a time it seems like, instead of it changing smoothly like before.
This can be quite jarring and takes away from the immersive experience that the simulator provides.
I understand that there may be technical limitations and challenges associated, but what we currently have is not it..

and we really need more cloud types to be fair
my previous post was not nice, got a bit emotionally invested haha.
this should be better, sometimes u just need to breathe and count to 10.

Can someone please explain why weather should take so much computing power? It’s a theme on here that gets trotted out over and over again, but it seems absurd… We don’t need MSFS to run the forecast models that MET offices around the world run on super computers. We need it to ingest the results of those models from some server and then add more or less wind / cloud / precipitation / turbulence. Or am I missing something? Even if the official atmospheric models are granular and limited in terms of their ability to model micro-meteorology, MSFS could interpolate / extrapolate a few parameters, no? What are we asking for? Ultimate fidelity with real world conditions in real time, or just believable weather?

it doesn’t have to require alot of computing power, that all happens server side from meteoblue etc.
we just get the data and the sim just renders that.
only possible compute that happens on our side are winds and thermals to some degree.
and the GPU to render the visual aspect of it all.

In this economy I highly suspect most users don’t have relatively new rigs that get 40-50fps. But then they shouldn’t be trying to run on Ultra either. I guarantee this is down to MS demanding feature parity on XBOX:X, and with things like CFD they have to claw back performance from elsewhere.

Volumetric clouds are heavy on GPU, especially large ones.

Ok, but GPUs aren’t computing the weather conditions, they’re rendering it. And maybe there are ways around that? Weather isn’t just large puffy clouds. What about the rest of the weather conditions that one might encounter? Like stratus? Or fog? Or haze? Or cirrus? Or whatever else.

There is 20km CFD too, though that will be CPU doing that work. That’s calculating winds over 20km radius.

Beacause it’s a ”flight” simulator. Besides the weather is already computed with those supercomputers. The sim only rendering that already computed data. It requires a bit of our gpu to be rendered.

You realize you’re basically responding with my point?

time to upgrade some hardware, sounds like. for now though set you Clpud rendering in Options to medium or low. some say is CPU, some say it’s GPU. may as well upgrade the whole kit and caboodle.

We want the weather to be a realistic replication of real weather conditions with all the common cloud types, different types of thunderstorms, different types of lightning, fog, snow, sleet, ice, updraughts, downdraughts, rain, and, etc.

All these conditions need to be calculated based on data from server or data the user has provided using the weather presets. Weather is dynamic and the weather conditions need to change to be as realistic as possible. These weather forecast and physics calculations requires a lot of cpu usage.

Then after all this all the weather has to be graphically processed and each layer of different weather conditions and lighting requires more gpu usage to be realistic.

Weather is very demanding environment for both CPU and GPU.

what was the point of this topic is there some sort of trolling happening here? you know the weather has been dowgraded and no hardware will bring it back right now

I realized that now. I’m sorry about that. Well, i agree we are not running the forecast simulation on our computers. It’s Meteoblue that has computers for that thing. MSFS only makes the data visually for us in the sim no calculations done for the visuals of the weather. We have different data injected since su7 that makes the weather look and feel worse. The weather in the sim will never look better than the data they inject into the system. If the data is generic the weather in the sim will also look and feel generic.

If Asobo doesn’t have data to show a thunderstorm realistic then Asobo need to create a thunderstorm because a METAR doesn’t know how the thunderstorm looks like. Only that it’s over the Airport or in the vicinity no other details. And create a thunderstorm visually realistic using volumetric clouds i bet is a really hard thing to do and then make it fit the rest of the global weather data that Meteoblue sends. And that is only for the thunderstorms. The weather we had at release were forming overtime as weather does IRL. And that weather were also already calculated to fit all over the world. Now they need to make two completely different sources fit eachother that may report completely different things because both types of sources has limits. METAR has limits of how to decribe weather visually but it’s more accurate, forecast models can describe weather more visually detailed but are less accurate.

They weren’t forming “as they do over time.” It was injected and bound to a loop within a box that would be updated (move) over time. It just looked better and the time was less granular so the loop had more time to play out and be unnoticeable (to most). It was rarely accurate in position/time, and alternately beautiful and laughable as to the accuracy of depicted weather.

There are still thunderstorms between METAR stations today. They’re off by 30-60 minutes, but they are there and as they finally arrive, the METAR barely has an effect on them (only affecting visibility, pressure, and wind). I’ve sat there and watched it do this.

As for the look, I think that’s low-hanging fruit that can definitely be addressed.

If the weather were not formed over time how do you explain this time-lapse then?

Right after release 2020:

Or this:
