Pixel Format Selector was developed to help you change the Windows Pixel Format used by 3DLinX. This utility is best intended for expert programmers already familiar with Windows, OpenGL, 3D development, and 3D hardware.
Changes to the Windows Pixel Format can have unexpected, and often unpleasant, results if not done properly. For a detailed description of pixel formats, see Ron Fosners book, OpenGL Programming for Windows 95 and Windows NT. Do use caution when making changes with this utility.
