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 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.

The smaller resolutions are used to concentrate the testing and place demand onto the GPU, thus offloading some dependency on system resources. Even still, Crysis appears to have a preference for the new graphical interface; even if it only hints at it in our results.

Even without Anti-Aliasing turned on, Crysis keeps both of the G80-based GPUs well below 60 FPS. It's clear that the CryENGINE2 is a heavy hitter, as the ZOTAC 8800 GT AMP! Edition outperforms the GeForce 8800 GTS 640MB by almost 27% and the GTX by just over 3%. Even with more vRAM available to them, the older 8800 GTS and GTX just cannot offer the performance of the G92 GPU paired with the PCI Express 2.0 graphics bus.

At 1280x1024 resolution, the results are still excellent but nearing the 30 FPS performance threshold for acceptability for both G80 units. In terms of performance, all products maintain the same performance ratio, which still gives the ZOTAC GeForce 8800 GT 512MB AMP! Edition a very big frame rate improvement.

Surprisingly, the three GeForce 8800 series products maintained a constant performance ratio between one-another throughout the Crysis benchmark testing, which is a good thing in terms of test consistency.

At the end of our real-world testing, ZOTAC's 8800 GT AMP! Edition outperformed the overclocked G80 GTS by a significant margin, and nosed out the GTX. Perhaps the new G92 core architecture is to be credited, or the new PCI Express 2.0 interface which allows twice as much graphics data bandwidth. Or perhaps MSI's 8800 GTX isn't much more than the overclocked GTS. Either way, our benchmarks certainly indicate that while the GTX beat the AMP!'ed GT in the other tests, it doesn't come close in Crysis.

EDITORS NOTE: After many months of using the Crysis demo for testing with the MadBoris Benchmark Tool, we recently started using the full retail version. Our initial tests have discovered that non-AA results were identical, but the 16x Q AA test produced very different test results. All of our previous results are still good for product comparison, but using the patched retail version of the video game (v1.21) has demonstrated that post processing effects (offered up to 16x Q AA) were not fully incorporated into the demo (limited to 8x AA). We have decided to address this matter in our Crysis performance comparison: demo vs retail forum discussion and welcome your comments.

In the next section Benchmark Reviews gives a detailed look into the operating temperatures of the GPU and component zones for the Geforce 8800 GTS.
