The VMR uses the graphics-processing capabilities of the computer's display card exclusively; the VMR does not perform any blending or rendering of video using the host processor, because to do so would greatly impact the frame rate and quality of the video being displayed. When taking advantage of the new features offered by the VMR, particularly blending of multiple video streams and/or application images, the overall performance obtained is highly dependent on the capabilities of the graphics card being used on the computer. Graphics cards that perform well with the VMR have the following hardware support built into them:
Note The VMR requires that the system monitor be set for a color depth of at least 16 bits. The VMR cannot be put into a run state if the monitor is set for 256 colors. Also, some video cards cannot perform Direct3D operations when the display is set to 24 bits per pixel.
