Using the OpenGL Extensions | Nvidia 2 specification

Using the OpenGL Extensions

This chapter explains how to use the OpenGL extensions supported by the NVIDIA driver for accomplishing frame synchronization of applications.

Frame Synchronization Using the OpenGL Extensions explains the principles behind swap groups, and describes the OpenGL extensions to use to control frame lock and swap sync functions.

OpenGL Extensions details the API calls for the extensions.
