I have been trying to use the 3D features of Adobe Photoshop CS6 Extended and have been having no success. I have enabled the 'Use Graphics Processor' in the Edit->Preferences->Performance dialog box. I have also ensured that I have the latest version of the drivers installed. The video cards (in a CrossfireX configuration) are Sapphire HD Radeon 7970s. The thing is, when I installed Photoshop a few weeks ago, I tested the 3D functions and they worked fine. Now they no longer do so. I have updated video drivers and Photoshop since then but when I reverted back to the older drivers, the 3D features still didn't work. I have tested OpenGL in Modo 601 and Houdini FX 12 with no problems. I was wondering if I am missing something obvious.
The funny things is, the 3d options are not grayed out. But more importantly, I figured out a way to fix the problem. I deleted the Photoshop preferences on startup using CRTL+SHIFT+ ALT and this fixed the problem. I am now able to use the 3D features. I suspect that somewhere along the way the preferences were corrupted and while it showed that the 'Use Graphics Processor' option was enabled, it may not have been.
Check into the Catalyst 13.2 beta display driver. It's cleared up several problems with Photoshop seen in every newer version since 12.8, which was a good version for use with Photoshop. I see they've just released beta 5. I've been running beta 4 and loving it - so much so I'm not sure I want to change...
