Yes. Increased mine to 96GB (on a NVMe SSD drive). I notice downloads since my internet is slow - 8Mb.

Definite improvement on second and subsequent times into new aircraft and areas.

I have career FBOs in 7 widely separate locations and  all those areas and aircraft seem to be cached.

Loading times after that initial access are a fraction of what I had in 2020. And I don't miss the wait while 2020 laboriously loaded and unloaded the world data between menu and flight. Having that single so-called digital twin is a huge step forward, especially if most flights are relatively short.

It is not credible to suggest that a network download could be faster than accessing even a massive cache on an SSD drive.

Please do enlighten up then.

I have from time to time played around with the size if ny rolling cache and put it on to a fast Nvme drive.  Every time I've used it for a while, I end up turning it off again, mainly because I do not see significant performance, I don't want to use up disk space and don't like all those writes to my disks unless I can see or feel a benefit.

It is true that using a cache keeps PG loaded when you are flying over the same area but if you have a fairly fast and uncapped internet connection, you probably don't need it (mine is 150 mb and seems sufficient).

Maybe it is different in msfs2024 - I will test it when mine arrives from the North Pole on the 25th 😀

It is. The developers said multiple times that the rolling cache is a vital part of MS2024 for it to cache scenery and aircraft that you use often. They recommend setting it at 100 Gig.

But didn't they say the same about 2020?

No, mines at 200Gig and it still seems to stream the same and CTD the same. Zero performance gains or improvements noticed.

First of all I didn't suggest anything, nor attempted to discredit or spread false info or profess to be an expert. I merely stated what I believe, based on my own experiences as an IT professional.

I have no cache at all. It is completely empty, I also get fast loading times on MSFS2024, without any cache whatsoever. Map enhancement clears it upon the start-up of the app. And yes it still loads faster than 2020 from my local dedicated NVME. Can you explain this?

2024 starts quicker because, during actual play, everything streams in real-time AFTER the sim has started, and this stream does not need to be that fast. It is only loading the basic thin client upon start up. The sim does not load the chosen AC, location or terminal, because it has no idea after it has loaded where you want to go, or which aircraft you want to fly. MSFS 2020 loads an entire sim at start up because it has to load and process everything in your community folder as well as it's assets beforehand. MSFS 2024 does not work that way. Thin client.

In both sims once you choose your location, aircraft, the loading times are roughly the same. To reiterate I said "I believe". I never said I knew. But if anyone here does NOT actually have factual info, they can kindly refrain from acting as experts. 

Find me factual info that details what exactly is saved in the cache for MSFS 2020 vs MSFS2024 and if the data is not the same, I will tip my hat. If default aircraft are being cached locally, then why not just have them downloaded in the official folder structure to begin with? What's the point? Ah, you say, well it's because aircraft are streamed in. Apparently NOT if they are locally cached on your drive. Which again begs the same question. What's the point?

As far as "Digital Twin" The latest buzzword from a handful gaming sites, how is MSFS 2020 NOT a digital twin? Does it NOT stream the exact same map data? In fact, it DOES and Asobo has confirmed this. So in 2024 they are rendering more trees have added rocks bushes and thicker grassy knolls/fields. These are autogen objects people, and are AI generated approximations of every tree rock, bush grass on earth apparently. And they even got this wrong. Not-to -mention rocks, bushes, grass and daisies just pop out of existence as soon as you are 100 feet over them. The only way to admire these assets is to walk around. Well then I guess it becomes a ground hiking and walking simulator, and totally useless as visible assets in the air.

I have seen trees in Europe and in North America where they are not even supposed to exist. The only true "digital twin" factors, are the bare maps themselves, along with PG. That's it and both sims excel at this. And so does Google Earth for that matter-no sim required.

What's the point of the thin client then, if you have to keep additional 100 GB committed for the game?

Wouldn't be more useful to pre-download wings, liveries, static aircraft and landing gears, which just appear from thin air when you rotate your POV at any airport?

Did you verify that with 100 GBytes of rolling cache this doesn't happen? (rhetorical question)

A few minutes ago I was getting this

And checking my bandwidth I get this:

In a cache they are automatically overwritten after a while when they are not used anymore. As an IT professional you should know that.

I would also expect from an IT professional, that he would have better idea about the "digital twin". MSFS 2024 is the best existing digital model of the earth mankind has ever created. It scales from looking at the whole earth down to every grass blade. MSFS 2020 is more a distant cousin than a twin anywhere below 100ft AGL 🙂

 

I've made mine 256GB...

Never even by far used such a big CACHE in FS 2020, but since FS 2024 is mostly streamable, and probably fully streamed if you set CACHE = 0, and I have a ~picky mental stress with consuming bandwidth, I decide to make it this big in the expectation that when flying over the same areas the scenery will be cached.

So far it appears to work because the FS 2024 app traffic ( win 11 traffic monitor ) only starts growing when I go fying in places I've never been before.

To get back to the original question, I did a quick test.

The A400 M is an aircraft I haven't used before.

I loaded it to runway startup at EGNS in the land of my birth and timed it. I was in the cockpit looking at blurred partially loaded instruments in 3:05. The thing was completely loaded at 7:18. My internet not's quick and I could see it at about 8Mb/s during this time.

Exit to free flight menu and did the same thing. The plane was fully loaded in 0:32.

Exited sim, restarted, same thing, in the fully loaded plane in 1:10.

This proves to my satisfaction that the rolling cache is being used for aircraft data. That's why I increased its size.

As to the digital twin name, certainly MSFS2020's implementation merits the name: it's just to a much lower level of fidelity. The point is that internally 2024 has a single model that is used for the world map in the menus, and in-game. 2020 had separate models that had to be loaded and unloaded separately. This is inefficient.

Really? Is that what cache is and does? Wow! I didn't know that! 

Grass, rocks, trees and bushes are AUTOGEN! They are layered onto the map and digital elevation model. That is the ONLY thing that separates the two sims. Their placement is arbitrary, and very flawed at that.

Pretty soon people are going to start believing that if they mow their lawns they will be able to tell by how short the autogen grass is in the sim if they fly over their own house.

The Map is the exact same map streamed into BOTH sims. ASOBO confirmed this. Photogrammetry is exactly the same as it was in the older sim as well. 

Do you really think that Asobo has actually mapped out every tree rock and bush at it's exact location in the real world? Ok then, there is nothing left to discuss. Carry on, and enjoy that digital twin. 

MSFS 2024 is no more a digital twin of the planet, than any other map provider out there, be it Google maps Apple maps Bing Maps or anything else with photogrammetry or 3D assets or objects.

Incidentally the first mention I heard of the term 'digital twin' was in fact aviation-related. In connection with the digital twins that Rolls-Royce maintain of their engines that are updated with telemetry from the actual engine (the analogue twin, if you like) for pre-emptive troubleshooting.

I'm using the Map enhancement mod on most flights. If the cache gets deleted every time I shut down the sim, then I guess the logical conclusion is that there's no benefit of using a huge cache when using the mod, no?
