Left 4 Dead: GPU and CPU benchmarks: Introduction
Like most of Valve's games since Half-Life 2, Left 4 Dead uses the familiar Source Engine, which has been upgraded with new effects that are usually used in movies. Among those are the not unquestioned graining and a reduced set of colors. How those new features affect the graphics can be seen in our article: Left 4 Dead: Graphics settings compared.

Left 4 Dead: GPU and CPU benchmarks: Benchmark sequence
Our benchmark sequence "Final Battle” takes place in the last fight the characters have to survive. Due to masses of zombies the real-time demo mainly stresses the processor. But flames, dynamic shadows and detailed textures are also challenging for the graphics card - especially at high resolutions.

This benchmark is a worst-case scenario. If you have more than 50 fps here, then the rest of the game will run smooth.
