I was looking through my settings and noticed that rolling cache was off.  Is there a benefit of turning it on?  I guess i never realized it was off but at the same time, not sure what I would gain by switching it on.  Thanks!

Leave it turned off.

It's one less thing that you might have issues with.

Rolling cache is used to cache the satellite/photogrammetry data of areas that you frequently fly in. So if you have a habit of returning to the same areas to fly in, over and over again, MSFS will cache those areas in your rolling cache file.  The first time you fly in an area, that area will be cached in your rolling cache file.  If you fly in a different area, that area will be cached in you rolling cache file too. This goes on until your rolling cache file fills up. Once your rolling cache file fills up, then I believe it becomes LIFO (Last In First Out).  That is, if you fly in a new area again and your rollling cache file is full, the last area that was cached will be removed so that the new area you are flying in now will be cached (hence the LIFO).

This becomes useful if you have a poor internet connection.  If you somehow cached an area you frequently fly in and that area is still in your rolling cache, with a poor internet connection, you should still see high detailed satellite/photogrammetry for that area, despite the fact that your internet connection is poor on that day.  Otherwise, if you have a poor internet connection on that day and the area is not in your rolling cache, you will probably get poor satellite/photogrammetry for that area.

I set my rolling cache to 10 GB in size because I frequently fly the same areas.  I believe from at Twitch Q&A, Asobo recommends that you don't set your rolling cache beyond 30ish GB.

I have a 16gb rolling cache and have run with it both on and off and at various sizes.  I find it particularly helpful when flying around photogrammetry cities and areas as it loads them and keeps them as you are flying around them rather than keep loading and unloading.

I would turn it ON if your not developing stuff inside the SIM, as a developer, I turn it off.

To further muddy the water, I turn off the cache in MSFS and use the cache in MSFS2020 Map Enhancement program which I use all the time.

I live in eastern Tennessee and Comcast has an internet data cap. Using a cache stops the annoying "You've used XX% of your data" emails they like to send me around the 20th of each month.
