<FONT FACE="Verdana" SIZE=5><H2>3Dlabs Permedia3 Display Driver</H2></FONT><FONT FACE="Verdana" SIZE=2>
<H3>SUMMARY</H3></FONT><FONT FACE="Verdana" SIZE=2><P>This is a display driver for graphics adapters basedon the 3Dlabs Permedia-3 chipset. It supports GDI acceleration, Microsoft DirectDraw® acceleration, Microsoft Direct3D® acceleration,and multiple monitor support.
This display driver forms a matched pair with the 3Dlabs Permedia3 video miniport driver. The miniport driver is responsible for non-rendering tasks such as adapter initialization, register mapping, and other resource allocation, whereas the display driver handles actual rendering tasks.<p>
This sample driver runs on Windows� 2000 on the x86 platform. It also builds and runs on Windows 98 and Windows ME.<P>
The driver is compiled as a DX8 driver and currently supports pointsprites, multisampling, volume textures and DX8 multistreaming (with a single stream).
<H3>RELEASE NOTES</H3></FONT><FONT FACE="Verdana" SIZE=2><P>
All applicable samples and DCT tests have been run successfully with this driver.
<H3>HARDWARE LIMITATIONS</H3></FONT><FONT FACE="Verdana" SIZE=2><P>
This hardware doesn't support the following features:
<UL><LI>Vertex shader processing<LI>Pixel shader processing<LI>Multistreaming (limited to just one stream)<LI>Hardware Transform and Lighting</LI><LI>Anisotropic and gaussian cubic texture filtering</LI><LI>Limited to two texture stages</LI></UL>
<H3>BUILDING THE SAMPLE</H3></FONT><FONT FACE="Verdana" SIZE=2><P>Type <B>build -cz</B> from the ..\disp directory. A successful build produces the video display driver perm3dd.dll.<P>
