Crysis

Publisher: Electronic Arts

We tested the game using the 64-bit executable under and DirectX 10 with the 1.21 patch applied. We used a custom time demo recorded on the Harbour map which is more representative of gameplay than the built-in benchmark that renders things much faster than you're going to experience in game.

For our testing, we set all the settings to High. Because of how intense the game is, we tested with both anti-aliasing and anisotropic filtering disabled at resolutions above 1,680 x 1,050 for the time being. There is currently no support for anisotropic filtering in the game, but you can still force it from the driver control panel.

There's an ever-so-gentle increase in minimum frame rate, but gaining just over a single frame per second will hardly change anyone's gameplay experience. Average frame-rates are consistent and largely unaffected by either memory frequency or latency too. This is worth keeping in mind when buying a gaming rig: buy "fast enough" memory with more money dedicated to the graphics card. Even the difference in base clock and memory controller frequency in the Lynnfield CPU makes no difference.

All the results are within an experimental difference of roughly one frame per second and despite us averaging a few runs, the results do not even show even a slight consistent progression that Crysis did.
