Hello so basically Ive figured out all the performance hiccups im having on mobiles are because my gameplay objects are created during runtime and there is no art for them in memory like there would be if i placed everything in layout.
Thats my conclusion because game after 1 minute of gameplay stabilizies and never has hiccups anymore.
Any ideas how can i battle this? It doesnt really affect desktop or webgl enabled devices but my main priorities lie with browser iphone and ipad + other devices that work with canvas2d only.
