GPU Cafe claims Adobe will introduce PhotoShop CS4 on September 23. The site writes the main attraction of the new version of this popular photo editing program is GPU acceleration, this new technology is expected to bring big performance improvements:
The main attraction around this release is GPU based acceleration; in short blistering real-time performance. This is possible by leveraging the massive untapped potential of GPU based processing. GPUs have leapfrogged CPUs in terms of parallel computational power and complexity for some time now and it comes as no surprise that the industry begins to realise this and various such non-gaming related tasks are off loaded to the GPU rather than the CPU. No wonder that Intel decided to join the party with Larrabee.
In CS4, applying textures, color or text on 3d surfaces will be done instantly. You can also manipulate an ultra-resolution images with ease and no slowdowns. Creating 3d panorams from a series of images will also see a huge improvement in performance. Apply a series of filters and previews will also be snappy. All these performance improvements are bonus on top of an incremental addition of new features.
