Question

Flash player 11 is too slow in Stage3D mode

I have recently installed the release version of flash player 11, and have been disappointed with its Stage3D perfomance. Suppose player is running in no-gpu-acceleration (software) mode, and my old ATI Radeon X-1600 card is not supported by release version (though card is able to render OpenGL 2.0). I had mentioned compatibility and perfomance issues for incubator build in this topic http://forums.adobe.com/message/3519994#3519994 and seems almost nothing changed since than.

How to define if hardware acceleration is really enabled? (the checkbox in player settings menu is selected).

This website, shown at adobe max keynotes, completely freezes my computer http://www.nissan-stagejuk3d.com/

My computer is Intel Core 2 duo 2.16gHz iMac, with ATI Radeon X-1600 video card, running under  MacOs 10.6.8

In your case, the player use the software fallback because your GPU is not supported

Known Issues

Stage 3D

  • Mac: On Mac OS X, hardware accelerated rendering is not supported on Intel GMA, ATI Radeon x1600, and ATI Radeon 2400 cards.

With the Hi res toggled On you should see antialiasing...

While this card can support OpenGL 2.0, we found that the drivers contained bugs which would cause some content to crash or even hang the machine.   When we find driver bugs we can not work around, we disable the card.   If Apple delivered new drivers in an OS update which resolved our bugs, we would re-enable.   This is an old gpu, however, I'm not sure Apple will be working on it.  

Does http://www.nissan-stagejuk3d.com/ crash with the official release (which would be in software rendering mode)?    Or in the pre-release build before we disabled HW support for this card?

Thanks Chris for your support and explanations. Stage 3d samples does not crash flash player, though CPU is overloaded in software rendering mode, so that computer nearly freezes.
