Testers needed

[las6]

Oh man. Keeps getting wierder.
The coarse culling does reduce the amount document writes (can also reduce the need for repaints), but adds a bit more logic overhead AND more importantly, adds a lot of animated objects as culled objects are being faded out and then faded back in when they reappear.

I guess my next step is to create a semi-automated test that would try differentiate between write, gpu and cpu speeds.

works good in ie , best in Chrome . ~ 25 fps averag

Opera beats Ie .

Yeah it looks like interpreting the wildly different results is going to make optimisations tricky.  I'm anticipating similar issues now that I'm developing for several different platforms....or at least trying to

Excuse my ignorance here   Do you have any idea what sort of ballpark performance we should expect from html5?  How much CPU & GPU access does it have compared to other programs?

Proper HTML5 (which this is not) should be plenty enough in most cases, since you're most likely drawing to the canvas using opengl with hw renderer.

What I'm experimenting with here is a method that would work even in cases where HTML5/Canvas support doesn't exist and I can use regular browser events to handle clicks, mouseovers and such...

very cool stuff

You like a challenge then

I'm really interested to see how html5 ends up being used.  In theory it might be capable of some great things, but all the power in the world is still going to be limited by how much data you can realistically transfer for truly online stuff.  If you have to wait a minute or more for data to transfer then the benefits are limited as far as gaming is concerned.
