// Place this file in After Effects/Scripts/Startup folder if your graphics card is an older model
// that can't handle large textures (symptoms include video noise or poor performance while
// dragging layers with OpenGL enabled). This script limits the size of textures to 512 x 512 pixels.
// If this script has not been enabled, the default limit is 2048 x 2048. Note that enabling this script
// sets the new limit in your preferences file, so re-disabling the script will not have an
// effect unless you also delete your preferences file.

// You can try even smaller values if 512 doesn't work (e.g. 256), or
// larger values if you have a card that can handle it (use at your own risk).
