"@makedit - if you are trying to maximise performance, you should enable WebGL. It's over twice as fast in Chrome and Firefox. Why have you disabled it?"
the last several times ive looked upon the webgl support of browsers i read something around 50percent.
codeflow.org/entries/2012/apr/25/webgl-statistics-and-the-state-of-webgl-html5
no support in ie, bad support in opera and safari. besides that i calculated even if the webgl support should be over 50 in the browsers people still have to meet the driver blacklist which is not really satisfying when ive tried it on several pcs (low to medium hard and software combinations - which i would call normal office pcs nowadays - but which all should run 99percent of desktop d3d and opengl games, and canvas2d too with the right browser)
so while i personaly like the idea of gl in a browser, i have tested alot of canvas2d prototypes and think these can be run at 30fps with medium graphic settings like a few parallax layers and 800x480 upto 1024x600 fairly well. thats why i guess im trading some gfx for more browser consistency.
so why do i switch wegbl off? there are some combinations ive encountered where webgl works, but is considerably slower than canvas2d and makes a game stuttering alot. but when a game is programmed within the limits of canvas2d of course theres no aaa gfx but it has a higher chance of working like it should. and people cannot mess it up when changing their browser settings, their hardware or update their browsers or drivers.
k for the problem i think ive nailed it down doing benchmarks in many browserversions:
Platform 9 (jump-thru).capx from the example folder
switched fullscreen off,
webgl off,
every tick - text to fps,
r84
opera 10.63 77fps
opera 11.50 79fps
opera 11.62 80fps
firefox 8 51fps
firefox 11 51fps
firefox 1401 54-56fps
chrome 13 58-60fps vsync disable didnt work
chrome 20 87-89fps
safari 517 78fps
r85
opera 10.63 37fps
opera 11.50 37fps
opera 11.62 35fps
firefox 8 53fps
firefox 11 53fps
firefox 1401 53-55fps
chrome 13 58-60fps vsync disable didnt work
chrome 20 87-89fps
safari 517 39fps
it seems the change mainly occurred in opera and safari. i cannot test ie9 because i have no win7 installation atm.
