This works well if you're reading a book and all the pages are vertically arranged, one after the next. You just scroll down and each successive page is waiting for you.
I think in your usage situation we would see a benefit from increasing the tile cache size (the tiles are the areas which you see getting rendered), and maybe pre-rendering tiles to the left and right. If you email me, I can send you some test versions with different tweaks. Or if any of the magazines you are viewing have a free sample copy online, you can point me to a pdf.

Just to be clear, I have only used the app in portrait mode and have been scrolling vertically. I'm set to full screen and fit width so there is no sideways movement anyway.
One thing I've noticed is that speed and smoothness is best with rendering ahead disabled, which surprised me.
The mag I'm using for testing is from a subscription but I could send you a copy if it would help. It's 113MB though.
