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.

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.

Out of all the cards tested, the EAH4870 DK Top is the only card that offers an average framerate above 30 FPS throughout all of the test resolutions. The HD 4830 and HD 4850 put in a solid effort, but at 1920x1200, you'll definitely want to go with the 4870. At framerates this low, the extra performance it offers will surely be noticeable.

Throwing anti-aliasing into the mix reveals results similar to those seen in the 3DMark06 testing. All cards show a dramatic decrease in average FPS, but the 4870 copes slightly better than the others thanks to its increased memory bandwidth.
