Crysis

Crysis is a science fiction first person shooter developed by Crytek, the creators of Farcry. It uses their latest game engine, CryENGINE2 which is the successor to CryENGINE, the engine used on Farcry. Some of the graphical features it has are as follows:

• Volumetric 3D Clouds
  
• Real time Ambient Maps with dynamic lighting and no premade shadows
  
• screen Space Ambient Occlusion
  
• 3D Ocean Technology dynamically modifies the ocean surface based on wind and wave direction and creates moving shadow sand highlights underwater
  
• Depth of field to focus on certain objects while blurring out the edges and far away places
  
• Vector Motion blur on both camera movement and individual objects
  
• Dynamic Soft shadows with objects casting realistic shadows in real time
  
• Realistic Facial Animation that can be captured from an actor's face
  
• Subsurface scattering
  
• Breakable Buildings allowing more tactical preplanning on the player's side
  
• Breakable Vegetation (with possibly heavy foliage) enabling players and enemy AI to level entire forests as a tactical maneuver or
• other purposes
  
• Advanced Rope Physics showcasing bendable vegetation responding to wind, rain or character movement and realistically interactive rope bridges
  
• Component Vehicle Damage giving vehicles different destroyable parts, such as tires on jeeps or helicopter blades
  
• HDR lighting
  
• Fully interactive and destructible environments
  
• Advanced particle system with fire or rain being affected by forces such as wind
  
• Time of Day Lighting, with sunrise, and sunset effects ensuring realistic transition between daytime and nighttime
  
• Lightbeams and Shafts when light intersects with solid or highly detailed geometry, and can generate "Godray" effects underwater
  
• Parallax Occlusion Mapping giving a greater sense of depth to a surface texture, realistically emphasizing the relief surface structure of objects
  
• Long Range View Distance of up to 16KM from in game measurements
  
• Parametric Skeletal Animation System
  
• Procedural Motion Warping

As well as supporting shader model 2.0, 3.0 and 4.0, the engine is also multi-threaded and takes advantage of hyper-threading and multi-core systems.

Unfortunately the 8800GT cards didn't want to play ball at the higher res. on the Crysis testing so I don't have any results for that. However, at other settings the results are all over the place. At the lowest settings the 9600GT destroys both the 8800s, but once the detail has been upped and AA thrown into the mix, it didn't stand a chance.
