Benchmark Results: Left 4 Dead
Left 4 Dead is a throwback to the grainy, gritty worlds of earlier games, but with somewhat-smoother round edges and slightly finer detail levels. Its popularity, rather than its system load, puts the game in today’s benchmark suite.
Even with a Core i7 at 3.83 GHz, Left 4 Dead appears CPU-limited at all resolutions for the GeForce GTX 295, while single-GPU cards start to run out of power when pushed beyond 1920x1200.
Adding 4x anti-aliasing and 8x anisotropic filtering allows us to see the beginning of the curve, where the GeForce GTX 295 finally starts to reach its limit at 2560x1600. Both of the single-GPU cards can play the game with complete smoothness at the highest resolution.
The 2 GB GeForce GTX 285 doesn't demonstrate the benefit of added RAM in Left 4 Dead, not even at 2560x1600 and 8x AA plus 16x AF.
