I just got a new iMac with a NVIDIA GeForce GTX 780M card. Will Photoshop support this card in the near future? Currently all 3D functions are disabled, and in Preferences Ise Graphics Processor is dimmed out, and there is a message that reads: Photoshop has detected an error in your display driver. Update or reinstall the driver and check Use Graphics Processor to retry.
Photoshop supports any working video card.
It sounds like your card's drivers are not entirely working. Please check with NVidia for driver updates.
Having a mac you are hostage to Apple to provide updates with the OS updates.
Strangely enough, when I went back into PS last night, Use Graphics Processor was somehow magically enabled. I checked all the boxes under Advanced settings and now 3D functions are enabled.
Not held hostage, but nurtured.
