I wonder if it's a cache/internet issue. Yes, zooming to extreme levels causes some delay. But scrolling through a map zoomed at a reasonable level should catch up very quickly on both offline and online map layers. At least, it does for me, and my phone is like 4+ years old.
Even though I use an offline layer, the online is actually faster to render. It's like the cache system is broken, even though it clearly works when the device is in airplane mode.
However, I will admit that OSMAnd is the least performant of the map apps that use OSM data (or any other map/navigation app, really).

Well yeah, if you get some beefy server somewhere else to do the rendering it will be quicker.
I don't know if Organic Maps and the like actually store vector tiles locally to get the speed up or what, but they're clearly doing something better.
