Since the rolling cache stores what you frequently use, is there a way to determine how much a particular area uses.

I normally fly in my area of the world which is North and South Carolina.  What size would I need to make my cache?

Would also like to get this info for a certain area in the world, like all the USA

I assume you mean MSFS 2020 since you didn't add a prefix, my experience is that you get the best performance by not using any cache at all if you have decent connection.

And you clearly didn't read the thread title. 😉

 

 

So to answer the question: The developers said ideally  you should set it to 128GB.

I did, and it wasn't any prefix then

Correct, the original title was Cache Size.

I’ve set it to 100Gb. Not sure how useful it is though since I fly all over the world.

This would be useful information, if we could get it. Of course one could experiment with a larger cache file, say 100 or 150gb's if you only fly in the US for example, and see what the result is.

I have mine set at 64GB but after reading the above, I wonder if t's really worth even setting it away from the default 16 GB 😕

Don't blame lxoie.  I edited the title when he called me out on it.

BTW, I have mine set to 96GB.  My concern is the less I have to stream, the quicker it will load.  I have 2TB to work with.

I'm curious about this too. I only fly in the UK proper, so wondering if my 1TB drive would hold everything.

I set my 2024 cache size to 50 gb on the recommendation of some on-line guides, just to see how it works. It seems ok, but now I find I can't reduce the cache size back to the default 16 gb to test.

How do i reduce the cache size back to the default 16 gb?

With MSFS closed, delete the file (.cc) with your Windows Explorer and relaunch MSFS. It will be back to 16GB.

I followed the last dev Q/A where S.Wloch talked about the cache. I set it to 256GB after 128GB and didn't notice any real difference, but I have fast fiber Internet connection.

I set mine to 250GB because I have the disk space for it. Maybe it helps, maybe not, I'm not really sure (placebo...!) but so far it didn't make things worse so I will stick with it for now. What else should I do with all that spare space... 😉

Thanks!

I have tested with 150 Gb in size and seen not so big enhancement. I reverted back to 16 GB (Fiber 2GB connection)
