NVidia GeForce GTS 450 SLI Performance Review

Author: Will West

With loud and fast moving zombies coming after you in endless waves,  Left 4 Dead 2 runs on the Valve's seven year old Source game engine, and runs well on even old hardware.  Even though it's old, it still pushes hardware and is a good game to run benchmarks on.  The storyline is simple; you and 3 survivors are found trapped in the middle of a zombie apocalypse and must find safety among the hordes of dead.

When testing Left 4 Dead 2 all of the settings were turned up to their highest, and Anisotropic Filtering was turned to 16X. Anti-Aliasing was turned to 8X to smooth out all of those jagged edges for a crisp visual experience.

Again, we have lots of long bars in this benchmark with the GTS 450 SLI coming out on top, and well ahead of the GTX 470.  Given the power of these video cards you cannot judge total performance using the lowest resolution since the framerates seem to top out at 170fpx.
