Crysis Benchmark ResultsCrysis 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. Low-resolution testing allows the graphics processor to plateau its maximum output performance, which thereby shifts demand onto the other system components. At the lower resolutions Crysis will reflect the GPU's top-end speed in the composite score, indicating full-throttle performance with little load. This makes for a less GPU-dependant test environment, and is helpful in creating a baseline for measuring maximum output performance in the next few test results. At the 1280x1024 resolution used by some newer 17" and most 19" monitors, all of the video cards tested performed at very respectable levels considering the earth shattering demand of Crysis.
In DX10 the HD 4670 stays within 10% of the 9600GT when 4x AA is applied in Crysis. Seems this card scales better in DX10 with AA applied compared to the nvidia cards but it still just lacks the raw muscle to put up truly playable frames in Crysis. I'll not bother to post results for 1900 x 1200 but all cards lost an average of 5 frames per second which mimics the results shown.
