S3 uses a variety of tabs on it's driver settings. The key tabs for games are the S3Config D3D and S3 Config OpenGL tabs. From here you can set your Vsync, use fast trilinear filtering (an optimized trilinear filter), Fast destination clear, Fast Z+Stencil clear, Detail level adjust, Max depth buffer size antialiasing and anisotropic filtering. On the OpenGL side of things, the options in the latest drivers are rather limited. The options are: Wait for monitor sync, Detail level adjust, and anisotropic filtering. The Gammachrome supports Antialiasing and Anisotropic Filtering to improve image quality in applications. Unfortunately, it does not support AA in OpenGL, only anisotropic filtering up to 16 taps. In Direct3D, the GammaChrome supports up to 4X AA and 16X anisotropic filtering.
