We've been working for about two months on a basic side scrolling game, with character movement up and down and parallax in the background.
However, now that we are at a demo stage and started testing, we found issues with the scrolling movement. We tested on the following browsers: Chrome, Firefox, Opera, Explorer and Safari. In chrome, the game runs fluidly, with up to 60 fps and no issues at all, but on all the other browsers, there are "stuttering" issues. We can notice slight stutter in the parallax effect and any object that we place in the background or foreground, as if there is a frequent micro delay.
After extensive research and reading through several threads on these forums, we tried some performance optimization tips, but with no positive results.
Next, we registered with Ludei, as we also saw in their promos that cocoon solves most performance issues. However, after going with cocoon and testing an android version on a Samsung Galaxy cellphone and Google Nexus 7 tablet, the same stuttering issues are still present.
Finally, we stripped the game down to almost nothing, just the character, a static background and one image of a plant in the foreground, and the same issue persists. You can check the stripped-down version at the following link (http://www.tenbolts.com/fish_game).
As an additional test, we went back to the template that comes with Construct 2 (flying along) and we noticed that the same stuttering is present there, too. You can check by exporting the flying along template as is to html5 and running in browsers to see that the green blocks at the top and bottom do not have a completely fluid movement in all browsers, except chrome where it runs perfectly.
This has us really baffled and we are at a dead end on how to solve this issue in order to have a fluid running game.
Any thoughts and suggestions will be much appreciated.
