Does anyone know if both of these can be on simultaneously? For example I have a few regions downloaded that are manually cached such as New York City. If I were to have both rolling cache enabled along with manual cache will the sim be smart enough to know not to download any data when I fly over New York City, and when I'm out of the area it will switch over to rolling cache?

Ditto... More generally,  is there an explanation of the cache system? How it works and how to set things up to our advantage? 

Would also like to know what exactly gets downloaded into the cache? I thought it downloads everything that gets streamed. I'm trying to figure out why the photogametry stuff still looks ugly and spiky even though I have my regions cached. I'm starting to believe this issue is due to either LOD radius and/or lack of VRAM.

One thing to be sure, never try to create a huge manual cache from the outset.  (it can always be increased later)

If you create a large manual cache (>50GB) on an HDD, you will be waiting all day while it pre-allocates.

On a fast SSD it didn't take more than a couple of minutes to allocate a 100GB cache for me.  (On a mechanical HDD I can see that being another story though)  Though I'm still not really sure what benefits it gives over not creating a manual cache... Some more documentation on this would definitely be nice.

+1 🙂 thought the same 

I have my home town Copenhagen cached (100GB allocated) so i expect rolling to kick in when leaving the area

This is true, I created a 512GB cache file and it takes 10-20minutes before I can make any sort of changes, and even then the whole experience is unresponsive, everything is extremely slow which makes it almost impossible to even create a new region. I'll have to delete and start over and start with a much much smaller size then. Perhaps anything more than 128GB will be slow, and I have an SSD. I recommend not going over that limit. Asobo/MS needs to explain and provide us with a bit more detail on the inner workings of the rolling and manual cache creation.

Agreed.

Just repeating, you can increase the size of the cache at any time, so it's just not necessary to create a huge one to begin with.

On a related issue, i haven't been able to confirm that it actually works as expected.

I flew over a pre-cached area, and used the performance monitor to see which files were being accessed, and the Manual cache file was never accessed.

Yes, it absolutely shows difference between HDD and SSD 🙂 I created a manual rolling cache = 50GB with non-superb and cheap SSD (some Patriot Blast 240GB I think), only SATA interface with speed <500Mbps, but it took only about 10 minutes.

Whoops, I have created a similar topic to this one. But to answer the original question, you can definitely have a rolling and manual cache active. However, I have been unable to reduce the size of the Manual Cache after setting it up, and can't see a way to delete it either, without manually deleting the .ccc file in Windows. As these both caches immediately block off the set size on your SSD or HDD as used space, be careful of being too generous. Setting a rolling cache and a manual cache at 100GB each will reduce the available space on your drive by 200GB immediately, regardless that the caches are yet to be filled with data.

I noticed that when flying over regions where I manually created and downloaded a manual cache, that I still see those spiky trees and photogrametry buildings out in the distance. I though that downloading the data beforehand would fix this issue but it seems to be a hit or miss in my case. Perhaps you're correct and there seems to be some bugs in the rolling/manual cache feature that MS/Asobo needs to look into. For the time being I will disable the manual cache and just use rolling cache until the problem can be further inspected. It's not worth the trouble and time to be defining manual regions for the manual cache when things aren't working how it should.

That's a big problem in this Sim it's like it can't stream quick enough in the distance, I was sure cache would have fixed it

I really think it comes down to VRAM, especially for those who fly in 4K. I don't think the problem is apparent in 1440p and under. The 30xx ampere cards with 24GB can't come soon enough. We 4k simmers will definitely need a card with as much VRAM as possible.

A decent explanation of the whole Cache system both manual and auto would be great, I'm not so sure manual is doing any good for me personally.

That's what I've been saying. It doesn't offer any benefits whatsoever for me. I've created several regions that I frequent fly around and it doesn't seem to offer any benefits whatsoever.
