Seeing how much progress has happened since then, it’s all really impressive!

The current iPhone 11 Pro seems to be locked at exactly 60 FPS and you can’t get it to drop.

Geekbench scores for your iPhone rage near 540 single core and 986 multi core. The current iPhone is 1330 and 3434 respectively. I would guesstimate that unlimited, FPS would be somewhere near 120 for the current iPhone. The app is very fast! I bet it could run on an Apple Watch!
