3DMark06 measures Shader 3.0 (i.e., DirectX 9.0c) performance. We run this software under three 16:10 widescreen resolutions, 1680x1050, 1920x1200, and 2560x1600, first with no image quality enhancements enabled – results we call “low” on the charts and tables below –, then setting 4x anti-aliasing and 16x anisotropic filtering. See the results below.
