Hi all,

As I have a 250 mb/s IN connection I was wondering if Rolling cache (and manual cache) is of any use ?

All suggestions are welcome.

Regards, Gerard

I turned it off since it happened to me that all trees suddenly disappeared. You read from time to time that deleting the cache resolves some issues, especially if carried over an update. My connection is also pretty fast (200mbit/s) and since turning the rolling cache off some weeks ago, I never had any issue with the flightsimulator. All I can guess is that this slightly increases loading times in regions that would be in the cache, might be a thing in photogrammetry regions as well, other than that? No need for this rolling cache...

Thanks ! Will turn it off too 👍

In one dev Q&A, they said it doesn't harm to keep it on. However. If you have a good bandwidth, also I don't see any good reasons to keep it on though.

 

The benefits for people with slow or expensive internet (playing on a tethered phone for example) is it may avoid a few stutters and will cut back bandwidth used, In your case probably no difference on or off.

If you are flying still in the same small area, the rolling cache can lower utilisation of your SSD. But if usually you are flying in a diverse areas, there isn't any reason to use the rolling cache, because it cache data, what you never use again or only small piece of this.

Here I fly in Europe + Turkey/Egypt

The only thing I could really think of is photogrammetry: I do not know if for example having a photogrammetry city like Venice fully loaded in the rolling cache and you return to this city on a later flight, if the loading of the highest LOD would be faster compared to the full streaming version. Guess an easy test would solve this, but as there were several tests showing that the manual cache also has no benefit at all if the internet connection is fast enough, I guess the same will apply for the rolling cache. 

I keep mine on even though I have a 60 mb/s connection.  I have noticed no performance differences but I do think loading time seems to be be faster. I also have a manual cache of my local area.

Running from an m.2 drive means file transfer is a lot quicker too

I have both caches turned off and I find MSFS more stable now, and with less scenery glitches.  I only use NVME SSD's now, so the data access/loading from them should have been quick enough.

I have a slower internet connection (only 6 mb/s) but I only fly GA, low and slow, so I don't notice any issues with scenery loading unless I 'teleport' to a new location using one of the various apps, then scenery loading and trying to catch up is to be expected of course.  I just pause it for ten seconds until it is loaded in.

I am concerned about how the Cache checks for updates, such as when they update the water masks and photogrammetry etc.  How does the cache know and change / overwrite the stored data?

I have also seen a few issues resoled by people flushing / deleting the caches, so for now, mine stays off.  It is another good idea, but solid implementation isn't yet perfect, and a better explanation of how the caches actually function and update if they need to would be a welcome addition.

If anyone knows, this might be a good thread to add that information so that people can make an informed decision about use of the caches, but we need solid information for it to be more useful, not people taking a guess at how it works.
