VIDEO GRAPHICS ARRAY COMPATIBILITY POLICY

It is policy that graphical application programs should be compatible with a conventional Video Graphics Array display, and capable of operating in 640 x 480 graphical display modes.

Requirement for software emulation of accelerated graphics displays

Any application software that utilizes 3d accelerated graphics should be capable of operating on a conventional 640 x 480 non-accelerated Video Graphics Array display. This means that the facility to emulate the 3d accelerated graphics display should be provided via software emulation, where practical.

Functionality should not be compromised due to the absence of 3d acceleration hardware

The application functionality should not be compromised due to the absence of 3d acceleration hardware, meaning the application should still be usable. It is permissible for application software to provide alternative functionality in the absence of 3d acceleration hardware.
