Crysis Benchmark Results
Crysis uses a new graphics engine: the CryENGINE2, which is the successor to Far Cry's CryENGINE. CryENGINE2 is among the first engines to use the Direct3D 10 (DirectX10) framework of Windows Vista, but can also run using DirectX9, both on Vista and Windows XP.
Roy Taylor, Vice President of Content Relations at NVIDIA, has spoken on the subject of the engine's complexity, stating that Crysis has over a million lines of code, 1GB of texture data, and 85,000 shaders. To get the most out of modern multicore processor architectures, CPU intensive subsystems of CryENGINE 2 such as physics, networking and sound, have been re-written to support multi-threading.
Crysis offers an in-game benchmark tool, which is similar to World in Conflict. This short test does place some high amounts of stress on a graphics card, since there are so many landscape features rendered. For benchmarking purposes, Crysis can mean trouble as it places a high demand on both GPU and CPU resources. Benchmark Reviews uses the Crysis Benchmark Tool by Mad Boris to test frame rates in batches, which allows the results of many tests to be averaged.
The very first thing we discovered during our 1680x1050 resolution tests was how well NVIDIA products performed compared to the Radeon product line. Test results like these begin to raise the question of how unbiased games like Crysis are when they proudly proclaim "NVIDIA: The way it was meant to be played". I don't consider this to be coincidence, but at the same time it's probably also not coincidence that Crysis demands more GPU power than any other product, which was perfect back at a time when AMD/ATI couldn't build a decent VGA product to save their lives (literally).
Analyzing the chart below illustrates two distinct trends. The first is that the Radeon HD4770 and HD4850 perform the same, and the 4870 is virtually identical in terms of Crysis gaming performance to the GeForce GTX 260. With no anti-aliasing added to Crysis for this test, nearly all video cards rendered a playable frame rate. Our Island time-demo mixes a some beach and water views, so it's going to be on the high side of frame rates when compared to actual game play. The results shown in the chart below illustrate (more distinctly) how well these products scale with anti-aliasing disabled.
Although the HD4770 has matched or closely trailed the HD4850 in most tests up to this point, the 512MB of GDDR5 operates on a thin 128-bit memory bus and can lead to bottlenecked data at some points. This became evident in our higher-demand tests, and for these reasons Benchmark Reviews excluded 4x AA tests like we normally provide in our video card reviews. We have also omitted our Far Cry 2 results (which are recorded at 8x AA) because the results were often too low to report or tests failed to complete.
In our next section, Benchmark Reviews tests with Devil May Cry 4 Benchmark. Read on to see how a blended high-demand GPU test with low video frame buffer demand will impact our test products.
