In this mode, stimuli are generated on the fly by the GPU either in a larger window for single display setup or fullscreen for dual-display setup. To learn more about GPU-based stimulus generation see the <a href="Support%20for%20GPU.html">GPU</a> chapter. Clicking on the "GPU Preview" returns to the texture preview mode. Note that the small preview inset always shows the texture version.</p>');
