Left 4 Dead
Left 4 Dead (L4D) is a 2008 co-op first-person shooter that was developed by Turtle Rock Studios and purchased by Valve Corporation during its development. Left 4 Dead uses Valve’s proprietary Source engine . L4D is set in the aftermath of a worldwide pandemic which pits its four protagonists against hordes of the infected zombies. There are four game modes: a single-player mode in which your allies are controlled by AI; a four-player, co-op campaign mode; an eight-player online versus mode; and a four-player survival mode. In all modes, an artificial intelligence (AI), dubbed the “Director”, controls pacing and spawns, to create a more dynamic experience with increased replay value. It is best as a multiplayer game with humans.
There is no built-in benchmark, so we created our own custom time demo which is very repeatable. The game is updated regularly by Steam and we chose the highest detail settings and 8xAA. Unfortunately Steam updated the game just as we began testing our GTX 590 and we had to create another time demo. It is very similar to the previous one but different enough not to compare to each other. You can see benches with the rest of the configurations in the Performance Summary.
We will save our comments until after we present both charts. First we test at 2560×1600 resolution:
