Crysis Test 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, and 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 at its maximum output performance, which 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 system performance. At the lowest 800x600 resolution available, frame rate performance often becomes entirely CPU dependant.
Crysis is well known for putting a substantial load on the CPU as well as the GPU, so it's a good test when you want a more balanced performance measurement. With no Multi-Sample-Anti-Aliasing enabled, the best P55/i5-750 performance is 9% better than the best AMD 790FX/720BE score. At its default clock setting of 3.2 GHz, the AMD 880G/555BE system takes a big hit in performance, over 10 FPS. Crank up the bus speed and the CPU multiplier, though, and it settles in half way between its two competitors, at 56.0 FPS.
Once some MSAA was turned on and turned up to 4x, the test becomes more GPU dependant, but it's interesting that the 880G/555BE turned in both the lowest and highest frame rates. Clearly, the CPU clock and the FSB (or equivalent) clock has a significant impact on Crysis; more than the number of cores and computational efficiency of the CPU. Turning up the wick on the 880G/555BE combination resulted in 18% and 16% increases in frame rates for the two tests. At higher resolutions, the differences were negligible, at least with the single HD 5870 video card I used for all the tests.
Crysis is the "Old man" of gaming benchmarks; let's take a look at one of the latest releases, Aliens vs. Predator and see if we can detect some CPU influence there.
