As the title says, how does it work? I currently have mine set to 100GB and I’m trying to stop CTDs related to scenery.
It’s supposed to cache Bing and PG data (whatever MSFS downloads from the Internet) in order to load it from the HD/SSD the next time you fly on the same area.
If you always fly different routes or altitudes it’s useless. 100 GB is very big, try 8-16 GB. It should have nothing to do with CTDs.
Personally I keep it disabled because it caused stuttering in the past and I have a 600 Mbit unlimited data connection anyway.

More like it causes scenery related CTDs in my experience. I’ve had to delete and recreate it when a new update comes out to get flights to load without the sim crashing.
So you have to delete and reload the cache after every world & sim update? Do you have to do this when you update the sim nav data from Navigraph?

I just tested it and found it made zero difference to performance or reliability… I think the only benefit is saving on data downloads. If you fly the same area frequently, it’s probably worth having, otherwise it’s a waste of disk space.
After every sim update I clear the rolling and manual cache files. For the rolling file you only have control over it’s size - it builds as you fly around. For the manual cache, you can specify areas to pre-download and cache.
Pretty sure it doesn’t include navdata. I don’t clear it after navadata updates. It’s a cache for bing maps (ground textures) and photogrammetry data (buildings). Photogrammetry in particular can be lots of data and can take a lot of bandwidth to get it all for a given city. I find the manual cache more useful for cities I fly over a lot if I want the buildings to look good. I just don’t have enough bandwidth to download all that data real time as I fly over. Not every city has photogrammetry data.
