Disable graphics acceleration in later versions of Photoshop.
Beginning in Adobe Photoshop CS4, the program has featured graphical acceleration. This allows Photoshop to use a desktop or laptop’s discrete graphics processor for rendering effects and processing, including 3D effects and objects. These features don’t work on all computers, and can slow down other applications even on graphics workstations. If you’re having problems with Photoshop or other programs, you can disable graphical acceleration and use the main computer processor for all Photoshop functions.
1. Click the “Photoshop” shortcut on your computer desktop or in your Start Menu. Wait for the program to start.
2. Click the “Edit” menu, then hover the mouse over “Preferences” and click “Performance.” If you want to disable all graphics card acceleration, uncheck the box marked “Enable OpenGL Drawing” and click “OK.” If you want to disable individual OpenGL features, continue to the next step.
3. Click “Advanced Settings” under “Enable OpenGL Drawing.” You can individually enable or disable Vertical Sync, 3D Interaction Acceleration or Force Bilinear Interpolation. Vertical Sync and 3D Interaction Acceleration are the most system-intensive settings.
4. Enable or disable the OpenGL settings of your choice, then click “OK.” Click “OK again, then close Photoshop. Graphical acceleration will be wholly or partly disabled the next time you start the program.
