Benchmark Results
Although we are uncertain about the exact quality settings used in-game, we selected the "hardcore" preset which is presumably the highest quality setting. That being said the 1680x1050 performance was surprisingly good with average frame rates soaring well above 60fps when using graphics cards such as the Radeon HD 6950 and GeForce GTX 570.
Regardless of how we tested, the Radeon HD 6950 and GeForce GTX 570 boards produced very similar results. Compared to our Crysis Warhead benchmark that sees the GTX 570 getting a ~5fps advantage, both graphics cards rendered considerably more frames per second in Crysis 2.
At 1920x1200 the GPU performance does decline considerably. The Radeon HD 6870 still averaged 42fps which interestingly is the same performance output than in our Crysis Warhead test. The GeForce GTX 460 and Radeon HD 5770 also produced similar performance when compared to our Warhead results.
The more expensive high-end cards such as the GeForce GTX 580 and Radeon HD 6970 were roughly 5fps faster than in Warhead.
Finally at 2560x1600 the GeForce GTX 580 averaged 39fps whereas it averages 35fps in our Crysis Warhead test. The Radeon HD 6970 managed a respectable 35fps score.
The GeForce GTX 570 was 2fps faster than the Radeon HD 6950. Beyond that the game was for the most part unplayable when using graphics cards such as the Radeon HD 6870 and GeForce GTX 560 Ti at this extreme resolution.
