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 and no texture compression.
You could increase the number of full screen 3D windows
possible by using texture compression.
3D acceleration is not supported when your color depth is 256
colors. In this color depth, there are too few colors to display
complex 3D textures.
