S3 ViRGE

S3 ViRGE/GX2 PC/TV - 64-bit integrated 2D/3D accelerator with TV output, AGP and PCI versions, 2-4 Mb SGRAM (83 MHz) or EDO (66 MHz) The main trump card was the developed DuoView technology , which allows you to use a monitor and a TV connected to the same video card at the same time in different resolutions (this feature will be implemented in Windows98).

The S3 ViRGE/GX2 chip fully supported the AGP standard. The big trump card is the presence of a TV-out and a standard set of filters that give a high-quality image on a television screen.

3D acceleration represented by the following features:
Flat and Gouraud shading
3D texture mapping
Perspective correction
Bi-linear and tri-linear texture filtering
MIP-Mapping
Depth cueing, fogging, alpha blending
Video texture mapping
Z-buffering

It is worth noting that S3 products did not prove themselves in the best way in games under DirectX, and the developed set of software tools for 3D graphics S3D was not widely used. Additional possibilities are opened by the PowerStrip program, which optimizes the operation of the S3 ViRGEGX/2 chip both in 2D/3D graphics and when using a TV monitor. The program theoretically removes some of the problems when working with the AGP bus in Win95/NT 4.X.
