Photoshop CS4 to have GPU acceleration?

But there appears to be a very effective solution on the horizon, a solution that is most likely more effective than anything else we have seem before and in our experience using Photoshop over the past 14 years. During a demonstration at Nvidia’s headquarters in Santa Clara, we got a glimpse of Adobe’s "Creative Suite Next" (or CS4), code-named "Stonehenge", which adds GPU and physics support to its existing multi-core support.

So, what can you do with general-purpose GPU (GPGPU) acceleration in Photoshop? We saw the presenter playing with a 2 GB, 442 megapixel image like it was a 5 megapixel image on an 8-core Skulltrail system. Changes made through image zoom and a new rotate canvas tool were applied almost instantly. Another impressive feature was the import of a 3D model into Photoshop, adding text and paint on a 3D surface and having that surface directly rendered with the 3D models’ reflection map.

This looks very interesting, and if it can be done on mainstream graphics cards then there's no reason why SLI (or crossfire, if it works) rigs should be built for photo editing.

What do you think? Progress, or just another gimmick?

For 99% of the designers out there, it's just another gimmick. I don't think the average freelance designer works with to many images more than a few hundred MB each, though obviously for the few that do have these seriously large images, it might be worth while.

$4-5 Billion should go a fair way towards it, especially if we get it from somewhere cheap like MSY.

For certain fields I think it will be progress, for print especially, one of the limitations of it is the resolution capabilites where there is a limit to how much you can reasonably process at once.

Running systems with quadros, 8gb ram etc I was limited to 300-600mb PS files before realtime editing was getting impossible, granted these were for large format, printing at around ~2x3m @ 300dpi.

The limitation is there, and that will certainly help.

It'd be brilliant for editing on a laptop, to be making the most of everything on hand. I've had CS2 chug a bit on me when trying to do some simple tasks, and realtime responsiveness when rotating an image would be absolutely fantastic.

It'd be interesting to try out a product that already makes use of the GPU for editing ( http://www.pixelmator.com/ - MacOS only) to see how much of a benefit it offers at this point in time.

I think it's a great idea. With new GPUs being so powerful, why not use their potential to make photoshop performance fly.

This WILL be a great advantage, Ive often worked with 1gb+ files in photoshop.

And the "paint on model directly" thing is AWESOME!
Ive been wanting to find a decent way to paint texture maps on 3d models directly for ages.. but with the level of precision of photoshop using a wacom pen. This will no doubt be what im after.

That's already possible if you know what you're doing, the same as it's possible to paint normal and displacement maps onto a model directly.

yeah I know, the technology has been around since deep paint 3d.

Z brush's paint attempt isnt that great..

being integrated with phshop however.. it should have the same accuracy and precision as regular wacom digital painting.

thats what I was getting at rather than being under the impression that this is brand new technology.

Most of the modeling apps I work with are good enough, and I personally would rather work with something that's purpose built for it, rather then it being a jack of all trades.

But yes, I can see the advantage if you didn't use any other programs.

edit: I guess what I'm saying is this: It might be great, who knows - but I'm not going to jump up and down about it until I've seen it's actually decent and usable.

Sadly, this appears to be pure rumour.

What amuses me is that Adobe won't be releasing PSP CS4 64 bit for Apple, because of the lacluster OS.

Actually, it's because Adobe didn't write their code properly. Apple had two major API's: Carbon and Cocoa. Carbon was only ever designed as a transitional API from Classic -> OSX. It's 32 bit only. Cocoa is the only way to write proper, feature rich apps on the Macintosh. Adobe never bothered to port their code ahead of time, so now Mac users have to miss out. It's not like they didn't know this, Adobe chose to not prepare themselves.

So it's really Adobe's lacklustre management that is to blame. Sorry for feeding the troll everyone, but I guess this is a question that others probably have too.

It's definately not a gimmick at all.

Just like the medical and scientific imaging applications of Photoshop isn't a gimmick, think you designers need to think about people other than yourselves.

This GPU acceleration is a massive boon for photographers, especially for panorama freaks and LF film guys.

Side note: Last time I checked still no 64-bit version of Maya for OS X, just Windows and Linux.

These companies like Adobe, Autodesk, etc, write (or buy out..) amazing software (better than Apple can), Adobe did write their code properly, or it'd be a lot slower than it is at the moment :P
