I build my current game with Cordova, and really the only major breakage i ran into with updates was iOS 9 audio changes. Patched howler, and it worked fine after that. I realize this is anecdotal, it would be interesting to see his/her game, what was so demanding to cause performance problems. Many platforms have their quirks and SDKs that you need to learn. I've had a lot more breaking changes with my React Native app. Opened the other day, and text boxes were overflowing their container. Didn't happen before. React Native is younger, so I find it's to be expected.
