OpenGL functionality in After Effects CS6 is different from OpenGL functionality in previous versions. This document is only for After Effects CS4 through CS5. For more information about After Effects CS6 GPU functionality, see this video.
This document can help you to resolve problems related to OpenGL that occur while you use After Effects. OpenGL problems can manifest in many different ways, including but not limited to the following:. For information about how to configure the preview preferences in After Effects for OpenGL and a list of features in After Effects that can be rendered with OpenGL, see Render with OpenGL in After Effects Help.
To benefit most from this document, perform the tasks in order. Record the tasks that you perform and the results of each, including errors and other problems. Adobe Technical Support can use this information to better assist you if you call. For Windows, some of these procedures require you to locate hidden files and hidden folders. By default, Windows Explorer doesn't show hidden files, hidden folders, and filename extensions that it recognizes.
See Show hidden files and folders in Windows for details. For Windows Vista, the steps in this document that mention the Control Panel are in reference to the Classic view.
For information on switching the Control Panel to the Classic view and many other common OS procedures, see Common OS procedures. These tasks can help you resolve the most common problems with OpenGL. Before performing any of these tasks, back up all personal files for example, After Effects files you created. Always restart the computer after a system error occurs to refresh its memory.
Continuing to work without restarting the computer can compound the problem. See this page for a list of system requirements for After Effects: Adobe After Effects system requirements. To determine what version of OpenGL your card supports, click the OpenGL Info button in the Preview preferences.
For information regarding supported OpenGL hardware, see GPU CUDA, OpenGL features. Newer video card drivers can improve the OpenGL capabilities of your card. See Update the video card driver below. Note: OpenGL does not support some features in After Effects, and the appearance of your composition can change between using OpenGL previews and software-rendered previews.
For the list features that OpenGL supports, see Render with OpenGL in the Rendering and Exporting section of After Effects Help. If the problem recurs, OpenGL didn't cause it. Drag the OpenGL plug-in back to the original location. If the problem doesn't recur, the cause of the problem is OpenGL. Many OpenGL problems or conflicts are solved by updating the video card driver.
Many video card manufacturers frequently update their software drivers. If you haven't recently updated the video card driver, contact the video card manufacturer for an updated driver, or download one from the manufacturer's website. Following a crash that an OpenGL problem on Windows causes, After Effects CS4 can automatically disable the Prevent DLL Address Space Fragmentation preference. This preference allows After Effects to access a larger amount of contiguous RAM, but can be incompatible with some OpenGL drivers.
Leave this preference enabled unless you are experiencing OpenGL or memory-related crashes. If you disable the preference because of an OpenGL problem, and you later update the video card drivers, reenable the preference. Then, test the problem again. Crashes or OpenGL errors can occur if After Effects attempts to use too much video texture memory. Texture memory is the amount of RAM on the video card VRAM. For example, the entire screen can turn white. See Mac OS Help or Windows Help for information about determining the amount of VRAM on a video card.
If After Effects displays artifacts or "garbage" blocks of incorrect pixels in the composition window, the video memory VRAM could be full, fragmented, or corrupted. Purge the image caches and video memory to empty the VRAM and let After Effects rebuild the composition preview. Note: Some screen savers that use OpenGL or Direct3D on Windows can corrupt the video memory if they activate while After Effects is running.
Change or disable the screen saver if you frequently have problems with corrupted images in the composition window after turning off the screen saver. See Mac OS Help or Windows Help for information about changing the video card or display settings. Most display card drivers include utilities that allow you to access advanced functions of the card.
In particular, anti-aliasing, and bit mode functions can conflict with OpenGL and cause After Effects to crash. Set the advanced functions of the card to their defaults, then disable the anti-aliasing and bit mode options. If you are using multiple monitors with an Nvidia card, set the Multimonitor setting to "Compatible". See the documentation for the video card or to the manufacturer's website for instructions on how to access its advanced functions.
If you are using multiple monitors and experience problems with OpenGL in After Effects, try the following:. The Reduce OpenGL Texture Size script reduces the amount of texture memory After Effects uses and can provide better compatibility with older video cards. A newer video card can improve the OpenGL capabilities of your computer and make the script unnecessary.
After you install a new card and its drivers, move the Reduce OpenGL Texture Size script back to the support folder. Then reset the After Effects preferences.
Re-create the After Effects preferences file to eliminate problems that damaged OpenGL preferences can cause. To re-create the After Effects preferences file, restart After Effects.
If none of the above steps has resolved the error or freeze that you are experiencing with After Effects, then contact Adobe Technical Support.

Last updated on Dec 21, AM GMT Also Applies to Adobe After Effects CS4, Adobe After Effects CS5, Adobe After Effects CS5. OpenGL problems can manifest in many different ways, including but not limited to the following: Adobe After Effects crashes or closes without an error while it starts.
A crash or freeze when you scrub the timeline or preview or render a composition. A crash when you change the settings of an effect while OpenGL previews are enabled. A crash or freeze when you enable or disable OpenGL previews. The composition window takes a long time to redraw. Artifacts or blocks of "garbage" pixels are drawn in the composition window. The composition window is drawn differently between when OpenGL previews are on and off. An error message such as one of the following: " After Effects warning: A problem occurred when processing OpenGL commands.
It's necessary to log on as an administrator to perform some of the procedures in this document. Update to the most recent version of After Effects. Make sure that the computer system meets the minimum requirements for After Effects.
Make sure that the video card and drivers meet the OpenGL requirements. Using OpenGL in After Effects requires an OpenGL card that supports OpenGL 2. Disable OpenGL to determine whether it is causing the problem. To disable OpenGL previews:. Deselect the Enable OpenGL option. Remove the OpenGL plug-in from the After Effects plug-ins folder.
To determine if OpenGL caused the problem, remove the OpenGL plug-in and restart After Effects. To remove the OpenGL plug-in:. Quit After Effects. Restart After Effects. Update the video card driver. Restart After Effects and test the behavior that caused the crash. Windows only. Optimize the Texture Memory preference. Set the Texture Memory preference in After Effects:. Click OpenGL Info. Enter the value you calculated in Step 1, then click OK. Purge the image caches and video memory.
Change the color setting for the video card to Highest 32 bit Windows or Millions Mac OS. Disable advanced functions of the video card.
Use a single monitor. If you are using multiple monitors and experience problems with OpenGL in After Effects, try the following: If you have placed the After Effects application window or the Composition panel on a secondary monitor, move the window to the primary monitor.
Disconnect all but one monitor. If you are using multiple display cards, remove all but one display card. For best results with OpenGL, use a single dual-head display card.
