Photoshop CS4 to include GPU acceleration?

Pixelmator uses CoreImage, which uses a GPU when available. I really can't understand why the Photoshop isn't using it.

We already know this story was pulled out of thin air already:

GPU and 64-bit are completely non-related. There's no reason why Adobe can't do this with the CS4 Mac. Pixelmator is "only" 32-bit and it knocks the socks off Photoshop as far as speed goes.

I think too many people are stuck in the videogame days where 16-bit was twice as good as 8-bit and 32-bit was better than 16-bit. 64-bit is *not* twice as fast or as "good" as 32-bit. In the case of Photoshop, 64-bit would mean giving PS access to more than 3GB of RAM... period.

Adobe Photoshop Project Manager John Nack, who gave the presentation cited in the TG Daily article, says that many of their claims are baseless. Regarding their claim of an October 1st release date for the next Photoshop release, Nack says that they "pulled a date apparently out of thin air." He also says that the technology he demonstrated has not been promised to appear in any particular future version of Photoshop.

I'd just like to second what Alex wrote above (and encourage a reading of the blog post he links to). While it's accurate to say that there was no mention of a Mac version, according to John Nack--the man who gave the presentation in question--it's also accurate to say that no one at Adobe has ever referred to any product under the CS4 name and that even the features being demoed may or may not find their way into any version of Photoshop in the future, let alone CS4.

Yea, what's the deal on the day late post? MacRumors posted this yesterday. :-|

Basically CS4 is pretty much a myth so far, October is a made up date and GPU acceleration is merely being demoed.

Did you even read the story before you wrote this?

If you look at the screenshot it is on a mac, and if you want further proof you can watch the demo at this link: https://admin.connectpro.acrobat.com/_a791863308/p40652716/ (it starts at about 18 minutes in) where you will see the demo done on a mac running leopard. I love tuaw but honestly this was just laziness.
