When you open Photoshop, the following error appears "Photoshop has encountered a problem with the display driver, and has temporarily disabled enhancements which use the graphics hardware" and features that require graphics hardware are unavailable.
Update your graphics driver and troubleshoot your video adapter hardware.
For solutions, see the following article:
To help guard against crashes related to problematic video adapters or drivers, Photoshop employs a small program called a GPU Sniffer.
Every time Photoshop launches, Photoshop launches the sniffer. The sniffer runs rudimentary tests of the GPU and reports the results to Photoshop.
If the sniffer crashes or reports a failure, Photoshop displays the message above indicating that it has detected a problem. Photoshop disables the Use Graphics Processor option in the Performance panel of the Preferences. On subsequent launches, the message doesn't appear.
If you correct the problem, either by updating the driver or replacing the video card, the sniffer will report a success on the next launch and the Use Graphics Processor option is enabled.
