Rolling Cache, Stream or SSD

And one can add to your post that people should note that the SSD speed is in MByte per second while fast internet is like 1000 Mbit per second. So an additional factor 8 difference. There is just no comparison: SSD is just way faster.

But then also to note that for MSFS 2024 purposes I find fast internet quite satisfactory/adequate.

You guys that fly high vs low and slow want to solve a ■■■■ ton of stutters and popping?

Turn off photogrammetry. Enormous difference and I don’t miss it a bit.

Lots of stutters resolved, better performance, and NO MORE terrain popping.

Turning off photogrammetry, using realistic settings, and auto tlod/olod management is the perfect combo for me for nice and smooth flying with no terrain popping.

People say micro stutters are a deal breaker or the stutter after looking down at instruments? I don’t know how anyone flies with rock trees popping in and out, buildings melting like ice cream and popping back in, and the distant land devoid of trees/detail/some buildings until they magically pop in normal or as melted mush.

This is all obviously subjective and personal preference.

Using MSFS 2024 on a 1Gbps internet connection I have a 300GB rolling cache set up on an NVMe M.2 SSD that writes up to 6,600 Mbps and reads up to 7,300 Mbps.

So why we do not get any informative good advice from the devs on this issue ?

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.

Thanks for doing all that! I read the thread and watched all the videos. Very weird. Definitely seems like a bug or bad coding?

All I know is that for me, turning off PG was the last piece of the puzzle for smooth, non-popping/melted flight.

Is PG beautiful when it is fully working? Absolutely! I will turn it back on when I get the same visual distance and non-popping/melting that I do with it turned off. I expect the performance hit, but not the other stuff.

Thanks again for doing that testing!

The problem is, the SSD doesn’t stream; instead, it makes many small accesses, and the data is compressed

That is just simply wrong, i/o, CPU, ram will “get” the data from SSD effectively no differently than direct from the internet, it’ll be buffer read exactly the same.

Quite simple, the rolling cache is slower than the one that gets the data from the internet.

Quite simple, wrong. Unless you are using a potato as an SSD. The rolling cache is no different than a page file or program .exe for that matter. According to that logic we might as well all load the entirety of FS from the cloud each and every time.

You may want to check your own AI.

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 on your drive and has to process them

That is just plain wrong. Thought experiment, where do you think the data for that internet stream is actually coming from in the first place before it is actually sent down the pipes to get to you?
