[image] Crashpilot77901: Look for FS2020 is rolling cache better, but for FS2024 not always. I see it differently. I keep rolling cache turned off in MSFS 2020 because I once noticed stuttering, and since then I haven’t turned it on. In MSFS 2024 it’s different – here rolling cache actually h…

[image] Crashpilot77901: Quite simple, the rolling cache is slower than the one that gets the data from the internet. I have to disagree with that statement. I have a 500 Mbs internet speed yet I’ve seen reads of up to 1.4 Gbs speed from my rolling cache which is located on a 7 GB/s nvme, muc…

Well, you would need a very poorly performing drive not to be able to match or exceed the speed of even a 1 Gbs internet connect. The best you could hope for there is 125 MB/s whereas even a SATA SSD would reach read speeds of over 500 MBs. That, plus the unreliability of the interet makes it a non …

The internet stream isn’t actually faster than your SSD. Your SSD is much faster.But streaming from the internet can feel smoother because the data comes in a steady flow. The simulator can process it more evenly.The rolling cache, on the other hand, reads a lot of small pieces from different places…

I get your point, but all I was pointing out was that your comment, “Quite simple, the rolling cache is slower than the one that gets the data from the internet”, is simply not accurate.

Quick question about rolling cache settings. My internet connection is via Ethernet and maxes out at around 50–60 Mbps. I’m trying to figure out what a sensible rolling cache size would be for that kind of bandwidth. At the moment I’m considering something in the 128 - 256 GB range, but I’m not su…

[image] NikitaSaxon: internet connection is via Ethernet and maxes out at around 50–60 Mbps. I’m trying to figure out what a sensible rolling cache size would be for that kind of bandwidth. I don’t think your internet speed should have any bearing on your rolling cache size. 128 to 256 should…

Yes, technically the SSD is faster, but only technically. The rolling cache makes many small accesses to the SSD, and the SIM also has to check data from the internet or the rolling cache, which leads to further delays. It’s like having 1000 hp in your car, but your exhaust system is too small to …

I would like to point you to my posting from yesterday related to PG and high settings that you all might find interesting. There is definitely a bug in there somewhere.
