0	31:29	Client : 03h – Render Processor

	28:24	3DState24 : 04h

	23:18	Reserved : 00h

	17	Mapping Cache Enable Mask : 1 = Update; 0 = Do Not Update

	16	Mapping Cache Enable : 1 = Enable, 0 = Disable (default)
		Any change made to the Mapping Cache Enable state variable must be followed by a
		GFXCMDPARSER_FLUSH instruction to cause the hardware to flush the 3D pipeline.

	15	Alpha Dither Enable Mask : 1 = Update; 0 = Do Not Update

	14	Alpha Dither Enable : 1 = Enable, 0 = Disable (default)

	13	Fog Dither Enable Mask : 1 = Update; 0 = Do Not Update

	12	Fog Dither Enable : 1 = Enable, 0 = Disable (default)

	11	Specular Dither Enable Mask : 1 = Update; 0 = Do Not Update

	10	Specular Dither Enable : 1 = Enable, 0 = Disable (default)

	9	Color Dither Enable Mask : 1 = Update; 0 = Do Not Update

	8	Color Dither Enable: 1 = Enable, 0 = Disable (default)

	7:4	Reserved: 0h

	3	Frame Buffer Write Enable Mask : 1 = Update; 0 = Do Not Update

	2	Frame Buffer Write Enable : 1 = Enable, 0 = Disable (default)

	1	Z Buffer Write Enable Mask : 1 = Update; 0 = Do Not Update

	0	Z Buffer Write Enable : 1 = Enable, 0 = Disable (default)

The frame buffer write enable feature can be used to reliably render coplanar (layered) polygons. An example of this type of layering would be to render a window on a wall. With a 16-bit z buffer, there is not sufficient precision to render this type of scene with consistent priority. Some pixels of the window will be intermixed with some pixels of the wall, due to precision inaccuracies.
