Photoshop CS4 depends on having a powerful and fairly new video card in order to make use of the GPU (Graphics Processor Unit). Some of us have been having problems getting it to work right. Whether this is a problem with the hardware, the driver, or OS compatibility is not clear.

I could see some articles about Photoshop CS4 Video Card Problems on many forums. But i did not get any answers on the same. Until and unless, i know the exact answers, i cannot write those things in this post. So, I will write more about these problems as soon as i find answers.

Photoshop CS4 depends on having a powerful and fairly new video card in order to make use of the GPU (Graphics Processor Unit). Photoshop users may take a while to move to the new 64-bit version of Photoshop CS4, but it's an important development; meanwhile, CS4 offers plenty of other significant upgrades to keep 32-bit users happy.

Owners of systems using OpenGL graphics cards will enjoy additional performance enhancements. After enabling a preference setting, you can zoom with infinite smoothness (rather than in steps) by holding down a key: If you hold down the H key while zooming, it zips to 100 percent so you can locate where in an image you want to work--at which point the view zips back in to the previous magnification.

Most of the Adobe Creative Suite 4 applications have enhanced features designed to take advantage of your display card's GPU (Graphics Processing Unit) to accelerate application performance.

This is the first commercial software we are aware of that leverages GPU acceleration, which dramatically improves the performance of certain components of the application. Features such as Camera Raw support and image blending were improved, 64-bit and 3D support added.

Changes made through image zoom and through a new rotate canvas tool were applied almost instantly. Another wonderful 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.

The display cards that were tested and are supported in Photoshop CS4 are listed in "List of tested graphics display cards in Photoshop CS4" .

Note: Photoshop CS4 takes advantage of only one GPU on your display card, even if more GPUs are present.

Adobe uses Graphics Chip for faster Photoshop CS4. Photoshop is a famously taxing piece of software, but beginning with the upcoming CS4 version, it'll be able to employ the muscle of your computer's graphics chip for the first time. The new version of Adobe's this flagship software product takes its first steps in using the graphics processing unit.

The graphics chip helps Photoshop CS4 for zoom in and out, rotate the canvas so artists can do a image for the best sketching angle, display and manipulate 3D objects, and handle color correction and etc.

Photoshop CS4 leverages the graphics display card's GPU, instead of the computer's main processor (the CPU) to speed its screen redraw. For Photoshop to access the GPU, your display card must contain a GPU that supports OpenGL and has enough RAM to support Photoshop functions--at least 128 MB of RAM--and a display driver that supports OpenGL 2.0 and Shader Model 3.0.
