hi
update your chrome browser (chrome version +60 ) and then preview your game on it it have a really great performance like +100% perfromance boost
but we can not use it because when crosswalk performance could be greate then crosswalk was stopped! yes we can use webview but how about they who don't update everything to last versions !? i mean in crosswalk you could trust, but webview ?! depends on user so i am sad and it i thing you are too!
