62 VPU Recover A feature designed to significantly reduce the number of system crashes caused by problems occurring with the graphics hardware. If the display driver detects that the graphics processor has hung, VPU Recover will attempt to reset the graphics processor, eliminating the need for a system reboot and allowing users to continue using the computer without interrupting or losing their work. YPbPr A type of analog composite video signal that splits and compresses the standard Red/Green/Blue (RGB) colors of a television signal into separate luminance and color values. The "Y" stands for the luminance channel, while "Pb" and "Pr" represent the blue and red channels respectively, both of which have the luminance value subtracted from them. It is an equivalent color space to the chrominance-based YCbCr, which is used for digital video. Z-buffer The portion of video memory that keeps track of which onscreen elements can be viewed and which are hidden behind other objects. In the case of a 3D image, it keeps track of which elements are occluded by the foreground in relation to the user's perspective, or by another 3D object.

A feature designed to significantly reduce the number of system crashes
caused by problems occurring with the graphics hardware. If the display
driver detects that the graphics processor has hung, VPU Recover will attempt
to reset the graphics processor, eliminating the need for a system reboot and
allowing users to continue using the computer without interrupting or losing
their work.

standard Red/Green/Blue (RGB) colors of a television signal into separate
luminance and color values. The “Y” stands for the luminance channel, while
“Pb” and “Pr” represent the blue and red channels respectively, both of which
have the luminance value subtracted from them. It is an equivalent color space

Z-buffer
The portion of video memory that keeps track of which onscreen elements can
be viewed and which are hidden behind other objects. In the case of a 3D
image, it keeps track of which elements are occluded by the foreground in
relation to the user’s perspective, or by another 3D object.
