Tested video
Adobe tested the following video cards before the release of Photoshop CS6. This document lists the video card by series. The minimum amount of RAM supported on video cards for Photoshop CS6 is 256 MB. Photoshop 13.1 cannot display 3D features if you have less than 512 MB of VRAM on your video card.
Important: This document is updated as newly released cards are tested. However, Adobe cannot test all cards in a timely manner. If a video card is not listed here, but was released after May 2012, you can assume that the card will work with Photoshop CS6.
Adobe tested laptop and desktop versions of the following cards. Be sure to download the latest driver for your specific model. (Laptop and desktop versions have slightly different names.)
