Turned them off weeks ago. Smooth as butter.

If you are using an SSD and have rolling cache on, you are reducing the lifespan of your SSD. Unless you know precisely why you need it on - you don’t. If you think you might need it on, you don’t. Switch it off and forget it exists.
 

I did a few flights tonight around Vancouver which uses Photogrammetry in the downtown core and normal rendering outside the core.  I tried doing a high quality manual cache, using the rolling cache, and turning off the cache. It made no difference at all to performance or visuals.

Now I have a 600Mbps internet connection and a ultra fast M2 drive, so I'm not sure those would reveal any bottlenecks anyway.  But at least for me, I'll leave it on. I don't see any reason to turn it off.

Well, if you have a super fast internet connection and a fast m2 SSD, you also have no reason to leave it on, no? Especially if you anyway don't see any difference, you have basically absolutely no reason to have a rolling cache. Think about all those read and write cycles on your m2 SSD and turn it off 😉

I guess if it is working as advertised, I’m saving some internet bandwidth for someone else like the lady in the other room watching Netflix ;). And my M2 drive is 50x faster than my internet connection so it makes me feel like it’s faster LOL. I don’t worry about write cycles. In fact the cache might reduce writes if you visit the same places. But Im sure the drive will be long replaced before I wear it out.

I agree, it would be hard to know if the cache is increasing or reducing write cycles, given most people tend to repeat flights, but overall no way to know without monitoring it.

Some people over in the flightsim forum are freaking out about 'hidden" Xvid drives shown in the device manager-disk drives list and deleting them. It should be noted that grayed out drives in that list are not necessarily even there. A history of drives is kept in that list. For example in my list there are several usb and external hard drives listed that I have plugged into my machine in the past, but are no longer plugged in. They are grayed out because they are not there. I have 7 Xvd drives listed, but only one is not gray. You can delete the one that isn't gray, but then you will likely have to reinstall MSFS. As far as the cache I used to have one but I noticed that the drive that had it was never accessed when MSFS started up or was running, even in areas I had just flown in recently. I deleted and turned mine off.

Virtual drives,  AND volumes.   Two different things in two different locations of the device manager.   Just to clarify.   The only reason I researched this is because of the strange volume  in Disc Defragmenter.    I don't like "mystery" items on my pc,   so I started researching.

I give, what is the rolling cache SUPPOSED TO DO?

According to Asobo, it is supposed to store detail scenery data as you fly over it, so that, if you return there, you do not have to stream it a second time, but can load it from the cache..

As best I can tell, it does exactly that.

Just curious what your cache size is set at? Is it a custom size? Realized mine defaulted to 0 when I turned it on...

So is it confirmed the rolling cache really works? I set mine to 64GB, which should store a decent amount if its actually doing its job.

Well that doesn't sound bad provided it off-loaded to a non main-thread core.  I tried with and without and didn't notice a difference.

Not entirely sure if bigger is better.... The bigger cache needs more CPU cycles to manage..  Asobo used to recommend 15 GB.

I suspect a big rolling cache would be beneficial if you have very slow and limited bandwidth internet and potentially detrimental if you have fast internet and unlimited downloads.

In other words if you are connecting to the net via cell phone with only a few GB of data a month set a big cache and try to restrict your flying to a few regular areas. If you are on 250MB or higher with unlimited downloads, just turn it off.  If your internet is somewhere in  between .. who knows? maybe just go with defaults.

I set it to 64GB back when I first installed MSFS. Maybe I should double check that.
