The performance of Adobe Photoshop CS2 is affected most by available random-access memory (RAM) and computer processor speed. Other factors can also affect performance, such as the options you select, system configuration, and the built-in limitations of Photoshop. Photoshop CS2 supports new maximum image dimensions, and file sizes requiring increased system requirements. The maximum file size Photoshop CS2 supports is 300,000 x 300,000 pixels, except for PDF files, which are still constrained by the 30,000 x 30,000 pixel limitation.
