I've been using Photoshop CS6 Extended 64-bit when one day the GPU acceleration features stopped working. I closed the application and restarted it and the GPU acceleration still didn't work. I couldn't rotate the canvas or use scrubby zoom. I rebooted my system and it still wasn't working. I check my performance preferences and my graphics processor was detected with the "Use Graphics Processor" box checked. I unchecked it and rechecked but the GPU acceleration still wasn't working. I uninstalled Photoshop CS6 and reinstalled it. I got the GPU acceleration to work opening the application right after the install. I close Photoshop CS6 64-bit and reopened it and the GPU acceleration wasn't working again. I am able to use GPU acceleration features in Photoshop CS6 32-bit with no problem. I'm running Windows 7 Ultimate 64-bit Ultimate Edition and I have a GeForce 280m GTX GPU. Would there be anyone out there who can help me with this issue. Thanks.
From what I gathered on this Forum there is a good chance that it may be related to the driver – unfortunately it could be either becasuse it’s obsolete or a bad new version.
This has happend to me also just now were you able to fix problem?
Hi. I didn't find a fix. The problem seemed to resolves itself one day. Not sure how but one day I opened Photoshop and the GPU features were working again. Although the computer I was using has a GeForce GTX 280m and driver support has been unsupportive. That may have been the issue. I did get a new computer with a GeForce 650m which hasn't encountered the GPU issue yet.
