Vertex Processing Selection Capability White Paper

Introduction

The purpose of this document is to explain what the vertex processing selection capability is and what the benefits are. The document is targeted for OEM’s, system integrators, and end-users that will be building or using motherboards with Intel® G965, GM965, and G35 Express Chipsets.

Terminology

TnL - Transform and light

PSGP - Processor Specific Graphics Pipeline: Code path that enables vertex processing and TnL (transform and light) calculation to run on a processor.

SWVP - Software Vertex Processing: Vertex processing that takes place on the CPU utilizing the PSGP

HWVP - Hardware Vertex Processing: Vertex processing that takes place on a graphics chip

Intel recently introduced the 15.6 and 14.31 Windows Vista* and Windows XP* graphics drivers that enables Shader Model 3.0, including support for hardware vertex shader and HW TnL, on the Intel® G965, GM965, and G35 Express Chipsets. This capability has shown enhancements in game compatibility as well as game play. Along with this capability, Intel also introduced a vertex processing selection capability that allows the drivers to switch between using the integrated graphics engine and the Intel® processors for vertex processing depending on the application. The end result is that Intel is able to deliver the highest possible frame rates by leveraging Intel’s world class processors.
