DX11: Crysis 2

The latest entry in Crytek's "Crysis" series launched in early spring of 2011. The initial release lacked DX11 support and was widely criticized for low-quality textures. A few months later Crytek released patches that provided DX11 features and more than a gigabyte of new high-resolution textures. Thus fortified, Crysis 2 is one of the most visually impressive games available.

I used the Adrenaline Crysis 2 benchmark tool to benchmark a scripted run-through of Times Square. I set the quality level to "Extreme" and turned on DirectX 11 and high-resolution textures. AA was enabled in the benchmark (although it's not a game option normally) to increase the load on these graphics cards.

  • Crysis 2 with Adrenaline Benchmark
    • Extreme quality, DX11 features, high-resolution textures, 4xAA, Edge AA, Times Square sequence

Cost Analysis: Crysis 2 (1920x1200)

  • $330.00 GeForce GTX 570 costs $7.75 per FPS
  • $480.00 GeForce GTX 580 costs $9.74 per FPS
  • $749.00 GeForce GTX 590 costs $10.01 per FPS
  • $320.00 Radeon HD 6970 costs $8.10 per FPS
  • $700.00 Radeon HD 6990 costs $40.00 per FPS
  • $499.00 Radeon HD 7950 costs $8.02 per FPS
  • $499.00 Radeon HD 7950 overclocked costs $7.23 per FPS
  • $600.00 Radeon HD 7970 costs $9.68 per FPS
  • Test Summary: The 6990's surprisingly low score is something I can't explain; I double-checked my settings and re-ran the test several times. Look how close the overclocked 7950 comes to the mighty GTX 590! It's only about 8% slower.
