pixi.js is doing amazingly well for us on all our android and ios devices except iphone 6 plus. First discovered in our own game, later on we found that it can be successfully reproduced using http://www.goodboydigital.com/pixijs/bunnymark/.
On most devices, it can keep 60 fps at even 50k bunnies, which is impressive. However, iphone 6 plus seems to be an exception. FPS drops to around 30 with just 3k bunnies, and close to zero with 10k.
Anyone has any clue on what's special with iphone 6 plus?
