Settings in the Preferences > Performance section
If a graphics card is detected on your system, its name and model will appear under Detectected Graphics Processor in the Graphics Processor Settings area of the Performance section.
- If your graphics card is supported, the "Use Graphics Processor" checkbox is enabled and checked by default.
- If your graphics card isn't supported, the checkbox will be grayed out and not checked by default.
- If your graphics card is supported, and the "Use Graphics Processor" checkbox becomes unchecked, this is likely because Photoshop has detected a crash caused by a defective graphics driver or configuration. See Troubleshoot Photoshop graphics processor (GPU) and graphics driver issues.
