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 (DirectX 10) framework, but can also run using DirectX 9, on Vista, Windows XP and the new Windows 7. As we'll see, there are significant frame rate reductions when running Crysis in DX10. It's not an operating system issue, DX9 works fine in WIN7, but DX10 knocks the frame rates in half.
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, and 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, but it is sometimes helpful in creating a baseline for measuring maximum output performance. At the 1280x1024 resolution used by 17" and 19" monitors, the CPU and memory have too much influence on the results to be used in a video card test. At the widescreen resolutions of 1680x1050 and 1900x1200, the performance differences between video cards under test are mostly down to the cards.
With medium screen resolution and no AA dialed in, the HD 5830 continues to have a field day. Please remember all the test results in this article are with maximum allowable image quality settings. Also, it's good to remember how all the performance numbers in Crysis took a major hit when Benchmark Reviews switched over to the DirectX 10 API for all our testing. Considering all that, 31 FPS is a great result, especially as it beats the GTX285 again. One frame/second isn't much of a difference in performance, but there is that $100 price difference between the two to consider.
At 1900 x 1200 resolution, everything looks the same; even the 512MB cards are still hanging in there. Those old HD48xx series cards were really good performers in Crysis, but they are giving up 8-12 FPS to the new ATI HD x8xx budget king.
Now let's turn up the heat a bit, and add some Anti-Aliasing. With 4x AA cranked in, the HD 5830 backs off ever so slightly, only making up 42% of the performance difference between the HD 5770 and HD 5830. It's not 50% or above, but is still a respectable result, and of course it squeaks by the GTX285 again.
This is one of our toughest tests, at 1900 x 1200, maximum quality levels, and 4x AA. Only one card gets above 30 FPS in this test, and it's the fastest single-GPU card on the planet, the Radeon HD 5870. In the middle ranges, the HD 5830 holds on to its spot, roughly half way between the HD 5770 and HD 5850. What I like about this test is that it shows how far ATI has come in one generation of video cards. The HD4830, which was the equivalent card in the HD48xx line up, only manages about 9 FPS, and the current generation card puts up 21. I see real progress here, and I just don't get it when people want to compare every card in the HD5xxx series to the HD4890.
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.
