# Audio/Video Options

Enable videos: Check this box to enable video playback in the display windows (playfield, backglass, DMD, topper). Normally, video files are displayed whenever present, in preference to still graphics, since videos provide a visually richer presentation. Still graphics are normally only displayed when no video file is available. If you un-check this box, any video files will be ignored and still graphics will be presented instead.

You can use this option if video playback is places too much of a load on your system. Alternatively, you can simply delete video files or move them out of the media folders, but this option is obviously more convenient if you only want to disable videos temporarily.

Mute videos: Check this box to mute video playback. Audio is only used for the main playfield video, so other videos are always muted.

Mute buttons: Check this box to mute the sound effects for button presses in the user interface.

Lock frame rate to monitor refresh rate: Checking this box throttles the graphics rendering rate in each window to the physical refresh rate for the monitor where the window appears. By default (if this box isn't checked), the program renders graphics as quickly as possible. On a machine with a fast video card, this can render internal frames much more quickly than the monitor's physical refresh rate, which wastes system resources by rendering lots of extra frames that never make it to the physical display surface. This can place a high load on the CPU or GPU (video card), which can have unpleasant effects like making your GPU fan run constantly. Throttling to the monitor refresh rate will reduce the unnecessary extra work.
