Benchmark Results: Left 4 Dead 2
Left 4 Dead is much more contingent on processor performance, but that dependency is only really prominent at low resolutions and without anti-aliasing or anisotropic filtering. At 1680x1050, we see the Lynnfield-based Core i5-750 delivering the highest frame rates, followed by AMD’s Phenom II X4 965. Those two are on even footing once you add AA and AF into the mix, though.
At 1920x1200 and then 2560x1600, it’s much harder to tell between the CPUs on our test bench. Only one thing remains consistent: the Core 2 Duo E8500 pulls up last place, making our past recommendations that you invest in a triple- or quad-core CPU all the more relevant.
