3D Mode Table
The 3D mode table measures the number of full screen 3D
windows that are possible to display at a given resolution. For
example, a value of 2.75 means that there is enough memory
left over in the current mode to run 2 full screen 3D windows
and another at 3/4 the size of full screen. A value of 0.40 means
that largest 3D window will be just less than 1/2 the size of full
screen.
In the following table, 3D windows are considered to use a back
buffer and z-buffer.
3D acceleration is not supported when the color depth is set to 256
colors. In this color depth, there are too few colors to display
complex 3D textures.
