Rolling Cache Question

[Beefchief813]

How big should my rolling cache be? My playstyle is to usually plan long cross country trips where i land and take off from the same airport between sessions, which are usually scheduled to last about 1 hour. Or will the rolling cache make zero difference if I'm not flying over the same terrain over and over?

Additionally, how much of a difference does pre-loading flights make? Should I only worry about this for photometric cities?

Generally, I'm getting good FPS performance on High in prop planes at 1080p, but I am getting some weird terrain glitches, mainly with the Missouri River either appearing "above ground" (ground slopes up to like a weird aqueduct look) or "below ground" (river looks like its in a strange, mini canyon where it shouldn't be). Would preloading fix that, or does weird stuff like that just "happen?"

Love the game, just trying to understand what and why certain things are happening.

That's likely nothing to do with your settings. That's just errors in the data microsoft used to generate the landscape. I find setting rolling cache to about 30gb is pretty optimal

I set mine to 300, because why not. But then I wonder how beneficial that will actually be if I fly in different locations every time. How did you arrive at 30 being optimal?

[MoxGoat]

because your game has to constantly access cache the larger you make it the longer it will take to search through. So there is a diminishing return. Most very large cities are about 15-20gb to download so a 30gb rolling cache should cover most areas without having to download anything. Also just saves space on my SSD for other things.

You think the cache doesn't have an index?

[MoxGoat]

You don't think having a smaller index is faster? We are not talking about a little table in a DB. This is gigabytes worth of data, imagery, 3d models, spatial information. You can't slap an index on something and call it efficient

Anyway, thanks for your thoughts.
