PaulloAmaral Ok, I recently discovered that if i changed all my "on every tick event" to "every 0.01 seconds" instead. The performance of the game was greatly and I mean GREATLY improved on all my mobile devices.
People often say something like this, but I have never seen it proved with measurements, and it technically is nonsense (since "every tick" runs every 0.016 seconds at 60 FPS, and "every" can't run more than once a tick, so will be the same as "every tick"). See Common mis-used events and gotchas.
Crosswalk basically works the same as Chrome which is one of the best mobile browsers available. Some Android devices have audio latency in the OS too. Either way Android L will have the full capabilities of Chrome in its web view so you'll be able to publish with PhoneGap. Also we regularly make tweaks to our engine for mobile browsers - just check the changelogs over the past few releases.
