When possible, Turbo Play can use a Direct3D Accelerated Previewer to preview your videos while editing. This is possible when no other layers are blended with the video.
When playing using the GPU accelerated player, video effects
are also accelerated by the hardware.
If you want to disable this feature, right click to the video part -> Video Functions -> Disable Fast Previewer. On audio files loaded as video, this is disabled by default.
When supported, the GPU Video Previewer can also preview videos with different video speeds and also in reverse playback
