“It’s not lost on us that when you look at the rate of GPU potential advancement, there’s an huge wealth of cycles we can take advantage of now,” (John Nack, principal product manager, Photoshop). He’s right, and in fact that release has been in the making for years. Adibe has been carefully looking at how to integrate GPU acceleration in its product. After all, a GPU is a “graphics” processor, right? Even whether it is mainly 2D (a new 3D object painting has been introduced), Photoshop does process pixels.

However, when performing intensive tasks, memory bandwidth and disk access are often more problematic than the pixel processing itself, and Adobe is

still looking for a great way to with that. Adding GPU acceleration in the user-interface for things like Zoom, Scale, Rotate and Effects Preview/Building is a great way to introduce hardware acceleration as the benefits are immediately noticeable. that is far from realizing the full potential of GPUs, but now Photoshop CS4 users have one more way to assemble their work a little easier. A 128MB graphics card is recommended.
