Our Half-Life 2 Episode 1 benchmark consists of Gordon emerging into the streets to find ant lions and Combine soldiers fighting. Gordon proceeds to kill a mother ant lion and lots of baby ant lions while generally blowing up anything in the way. The gravity gun is used to push a couple of cars over ant lion dens, then some more Combine soldiers are killed. The timedemo ends after Gordon enters a small room and sets off a mine. (No, I didn't accidentally die, I'm not a noob!) Overall, the timedemo is pretty representative of gameplay.
All of the in-game graphical settings were set to high. The "Reflections" drop down menu was set to "Reflect All." The "HDR" drop-down menu was set to "Full." Anti-Aliasing and Anisotropic Filtering were controlled through a batch file which changes the in-game settings. After the batch has finished running, the average frames per second for each test is output to a file. For each test, the timedemo was run three times and the results were averaged. The game was up-to-date as of 10/9/06. Note: HL2 Episode 1 uses a unique method of implementing HDR, and the NVIDIA cards are actually capable of HDR + AA in this game.
