Re: Yay
The Flash player isn't intended for 3D. It's intended to be a minimal-size installation for simple 2D graphics - considering the size of the installation, it's pretty successful.
The Shockwave player was meant to be the all-singing all-dancing version with 3D and other effects (variable transparency like smoke effects, etc) but I don't think it really took off.
I'm no expert but I expect Shockwave makes use of your computer's own 3D capabilities (GPU) while any 3D effects done in Flash are calculated on the fly by the resources allocated to rendering the webpage. Wrong tool for the job, in other words.
What would be more useful is if Adobe added an option to the right click menu for 'block Flash from this domain'. Flash adverts are the bane of my existence. The Firefox plugin Flashblock is a must-have, but provides an opt-in rather than opt-out (or whitelist instead of blacklist, if you prefer).
