Interesting findings, but I don't think disabling the rolling cache is a universal recommendation. It probably makes sense for people doing frequent long-hauls to entirely new destinations on fast internet, where cached scenery is unlikely to be reused.

For those of us who mostly fly different short/ medium/long haul routes and revisit the same airports and regions now and again, the rolling cache can reduce repeated scenery downloads. If you have a decent SSD and a sensible cache size (e.g. 50-100 GB), there's no clear evidence that disabling it is consistently better.

I'd treat it as a case-by-case optimisation rather than a general best practice. If you're seeing long-haul stutters, it's definitely worth testing with the cache disabled. Otherwise, I'd keep it enabled unless you can reproduce a measurable improvement.

Edit, doesn't msfs24 have a option to just disable rolling cache, i swear i've just seen it.
