Tuned off rolling cache and the stutters are reduce for sure. Anyone else?

Ive turned mine off also,, I dont think it even works,,,I did not notice better performance with it on after repeatedly flying in the same area with it on and off. Maybe on a super high end computer ?

Considering how long it takes to manually cache an area  the idea that you can have a rolling cache that is writing scenery to your disk at the same time you are rendering it sounds like alot to ask of a computer unless its really high end, Not alot of info about what exactly its doing is available.. maybe its one of those things they pit in the game witht he intention of improving it later,

Interesting, maybe. On mine its like a different sim including the ground traffic is more smooth. No stutters on landing.   

Noticed an interesting thing as I was troubleshooting stutters on a friend's install today. Fresh install with the latest patch and navigated over to data settings - rolling cache was enabled but the default set was 0GB. Disabled the setting, deleted the cache (not sure it was necessary), restated the sim, and noticed the stutters were certainly reduced.

Wonder if this default misconfiguration is causing issues on other's installs. Could anyone confirm what the default actually should be? I've had this setting off since day-1 and can't remember if it was ever set correctly.  

On a side note,  curious how many Xvd drives you see?  (virtual drives)

Last night I had 17 hidden,  one visible.  Every time that 2020 starts,  another is created and added to the list in device manager.

Just one here...thankfully!

Did you select "View / Show Hidden Devices" in Device Manager?

I am wondering also if having a HD versus SSD for rolling cache stutters makes a difference.

Maybe HD impacted more by slower transfer speeds .

Presumably the THEORY was that if you had already downloaded the data for where you are flying then it is a minimal extra load to save it to disk in case you need it again later.

Whether that actually worked out that way in practice is another question altogether.

 

I thought it is less about „load“ but rather limiting internet data usage for those who have no data flat rate or weak data connection. Unless this is what you refer to as „bandwidth load“ vs cpu load

In terms of overhead it is going to depend a lot on whether the local cache is mainly just disk writes or uses a lot of CPU/GPU to preprocess the textures being cached.

If it happens to be mainly disk writes then putting the local cache on a separate SSD that is not otherwise used by the game for anything else should help.

On the other hand if the stutters are due to the system waiting till it gets available CPU or GPU to do some sort of funky compression before writing, then the drive used by the cache will not matter much.

i guess we will never know for sure untill MS tells us exactly how this thing works or is supossed too,, maybe dx12 will help.

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.

The other thing to keep in mind, is that there is barely a subsystem of this software that is completely bug free. Every aspect needs some attention. Why would the cache system be any different? It wouldn’t surprise me at all to learn the cache system was bugged... maybe in a niche way, or more broadly. Until someone does some rigorous testing, all we can do is speculate, try it both ways and decide for ourselves.

Agreed. Might be a good one to bring up for the next dev Q&A. Is the only use case for it in bandwidth / data usage scenarios, or are there actually some performance benefits to enabling it (that would be the only other reason any of us would want it on).
