I had this “problem” all the time … since 2020 launched … and with 2024 even more: How does the RollingCache really work? … I mean … really In FS2020 it was very quickly obvious that the cache mainly causes problems: With sim updates it could cause hangs (e.g. due to asset conflicts) In regular c…

HighReuse is a good concept. I like it! Kind of obvious as we tend to have favourite planes and airports. Although to me HighReuse simply means install permanently. End of problems. I would go as far as storing HighReuse textures uncompressed, for the fastest load times. It would be interestin…

[image] nenenui: Perhaps Asobo is sitting on top of the Azure Blob Storage stack and has no “easy” way of modifying the Azure caching algorithms to really fit the FS2024 usage patterns. Interesting and disappointing if true. I’ve had a very frustrating time with the rolling cache, such as it …

Today the 4th beta of SU2 was released … and there is still no item which clearly references “changes to the caching and streaming” pipeline. I doubt that SU2 will see any major changes, because I would not expect Asobo to release such fundamental changes without an extended beta test period. To s…

For performance reasons should the RollingCache.ccc file be saved on the same drive as Packages (i.e. Community folder, Stream Packages, etc.) as opposed to in the LocalCache folder on C: while everything else is saved on D:?

IMHO it does not matter … as long as you have enough space on that drive. Disk access speeds do not seem to be the real issues with the RC. From what I have seen I would say the big issues are: The RC is not good a caching important data … ergo … too much unnecessary very slow network access to …

To me the Rolling Cache negates the whole point of streaming the sim. What is the point of streaming to save on installation if you have to download it to disk anyway during play to get a good experience? I think Asobo really need to look at how we balance streaming and installation. Sure with st…

@nenenui this thread is amazing. Albeit it’s above my head at points but your insight is extremely thought out and throughout. Quick question - What software are you using that’s allowing you to see how the read/write of data is occurring within the rolling cache?

You will find this pointer in the very first (summary) post of this thread: Useful Windows Tools for analysis Resource Monitor … Process Monitor Provided by Microsoft for free via the regular app store as part of the Sysinternals Tools. Performs a highly detailed analysis of almost all system…

Interesting item in SU 2 v1.4.14.0 … https://forums.flightsimulator.com/t/sim-update-2-beta-1-4-14-0-release-notes-april-18-2025/717378 Stability & Performance … Improved rolling cache usage Sadly no additional information. So we will have to wait and see.

Hoping you can look under the hood and see what may have changed.. Always enjoy your reports.

RollingCache.ccc performance debugging and tuning … How?
