thank you

Well what i was trying to test was the performance of chrome verses IE9. I made another version of the test with the layout 800x600 and the window 800x600. Chrome can't handle it, but IE9 has the same performance.

My conclusion is that as your window and layout gets bigger IE9 has better performance when dealing with many physic objects.

The same is true when your sprites are big.

I made a performance test game so i could learn why my game ran faster in IE9 then Chrome18. The following test game displays the fps and physic objects on the screen. Every 0.25 seconds it adds another object. It also randomly applies a impulse to each object. Once the fps drop below 58 it stops adding objects. The conclusion was that chrome was able to handle about twice as many objects then IE9. So i still don't have a answer to my question.

Does anybody know the performance difference between 0 opacity and Invisable?

Well if Chrome is the best why does it run the game I made at 44 FPS when IE9 runs it at 60 FPS???

Well after some searching on google i found that the mime type for m4a audio was not setup on my webserver. I fixed that problem and now i have audio with IE9 working. Chrome FPS is now 43 after the change.

Well I know why no audio with IE9, it only supports AAC and MP3 audio. I Used HTML5 Test to test my browsers and IE9 scored 138 and Chrome18 scored 400. This still doesn't tell me why chrome is running at half the speed of IE9.

I just updated my video driver and made sure i'm using the latest of IE9 and Chrome. I still get the same results. I then found a benchmark test that mentions that chrome is really fast for 2dcanvas and doesn't even list IE9.

HTML5 Performance Benchmarks

I guess my question is why/how could IE9 be performing this much better then Chrome?

well here is the game Marvin the Marble

The problem is that when i test it in the preview browser with Internet Explorer it works perfectly. I get 60FPS and sound works. When i copy it to my webserver no sound in Internet Explorer.

Now my problem gets worse with Chrome. I get sound but the FPS drop to 34.

I'm going through the code still, but nothing that would solve the problems.

great job on the animation of the main character. I would like to know what software you used?

Thanks again, i did it the hard way at first.

That should work. I just couldn't think of how to do it.

Thanks
