Photoshop provides you with dedicated GPU settings in both the Performance and 3D sections in the Preferences dialog.
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 enable and checked by default.
- If your graphics card is not 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.
Advanced Graphics Processor Settings
To fine-tune the card’s performance, click the Advanced Settings button.
Adjust Drawing Mode:
- Basic: This mode uses the least amount of graphics processor memory to run the most basic OpenGL features. Use this mode if the Normal and Advanced modes seem to be less smooth in their performance. This can happen when you routinely run other programs that occupy graphics processor memory. Select this option if you notice bad screen redraws or slower performance when using GPU-accelerated features.
- Normal: This mode uses a large amount of graphics processor memory to support advanced OpenGL features to perform color matching, tone mapping and checkerboard blending. This frees the CPU to perform other tasks.
- Advanced: This mode uses the graphics processor most intensively. It uses the same amount of memory as the Normal mode while enabling more advanced techniques to improve drawing performance. This setting is best when working in 3D or when working extensively with the GPU-accelerated features. If this mode seems to perform less smoothly, try switching to Normal or Basic mode.
