Half-Life 2 is a popular franchise and we benchmark the video cards using Episode Two with the aid of HOC Half-Life 2 Episode Two benchmarking utility using the “HOC Demo 1” provided by this program. We ran the game in three 16:10 widescreen resolutions, 1680x1050, 1920x1200, and 2560x1600, under two scenarios. First with quality set to maximum, bilinear filtering and anti-aliasing set to x0. This configuration we are calling “low” on the charts and tables below. Then we maxed out image quality settings, enabling x16 anisotropic filtering and 16xQCS anti-aliasing. This configuration we are calling “high” on our charts and tables. We updated the game up to the June 9^th 2008 patch. The results below are the average number of frames per second (FPS) achieved by each card.
