I just changed from 16 GB to 700 GB. But I had no real performance problems to start with. Anyway, in the Dev Stream they mentioned more than once that using a large cache would help cure performance and instability.

I think it may prove out that a larger main drive, or having two if the MB permits, will prove a better upgrade than more RAM. You don't need the latest spec expensive main drive. The cheaper, older spec versions work fine. And then make a 1 TB cache or larger. Something like Tom's Hardware have detailed tests to show you which are the bargains.

I suspect that making the cache too large might be counterproductive when it takes the game more time to search through a huge cache compared to simply fetching the required data from the internet.

100gb seemed to be a reasonable cache, to me.

I am not sure the present 16 GB cache is being used by the program.. It seems that airplanes and textures do not carry over from session to session.

Yes. I use 100GB cache and I often fly in central europe with the same aircraft. Loading times are very fast because the aircraft is already in the cache.

I don't believe the cache stores AC data or other sim objects & assets. Just topographical map data and photogrammetry. If you use the Map enhancement mod, it clears the official MSFS 2024 cache upon start-up.

I set the cache to 128GB a couple of days ago. Done lots of flights since then, but I haven’t noticed a difference.

It's a Mystery.

I tried to reduce the rolling cache from 100GB to 64GB and a message popped up saying you can't reduce the rolling cache, you can only increase it!
I was going to try the Reset to Defaults option, but don't know it that will reset all MSFS2024 settings, or just the settings in the currently selected Online category where the rolling cache is.

Set mine to 1TB, it reduced it to 500GB. Haven't had any issues.

Close MSFS, delete the file ROLLINGCACHE.CCC wherever you put it and relaunch MSFS. It will be back to 16 GB.

"Thinner client" 🙂

Never forget that the rolling cache is used when you fly over a place for the second time. When you fly in a new area instead, it just writes data on the SSD, causing more stutters. At least on MSFS it did - that's why I kept it disabled for 4 years - and I have no reason to believe that it was improved in FS2024.

In MSFS 2020 I turned off the rolling cache about three years ago. Never had an issue. Even with default Bing maps. At least in the older sim.

For msfs 2024 I've set it to 100Gb, but since I'm an avid user of Map enhancement, it gets deleted by the aforementioned app during every startup. It has to do this due to the fact that it (rolling cache) cannot be turned off in MSFS 2024. The app's creator implemented this, in order not to get Default Bing map tiles mixed in with whatever other map that one may streaming from the app. 

In either case I do clear the app's own cache from time to time, just to ensure fresh tiles so-to-speak. At least in the older sim, regardless if I use Map enhancement or not, I never have to worry about mixed map tiles, as the sim's cache is turned off.

Having no way to turn off the cache in msfs2024 is just another inconvenience on MSobo's part. I see no good reason to not have an option to do so, other than throw a small wrench in the usage of third party maps- which incidentally, the creator of Map Enhancement has found a way to overcome. 😛

And that's where you are mistaken.

No.  It's gone from a low texture stuttery mess to a low texture stuttery mess, until I gave up last week and went back to 2020.
