Chrome Engine 4 is a complete game development framework developed by Techland (leading Polish computer game developer). Chrome Engine 4 is available for PC, Xbox360 (and shortly Playstation 3). The PC engine is optimized for both DirectX 9 and DirectX 10.
Here is an overview of Chrome Engine 4′s features: high dynamic range (HDR) rendering, support for all modern per-pixel lighting and rendering techniques, anti-lights (I like this term!) which make preparation of obscured places an undemanding task, deferred shading and lighting, soft shadowing, subsurface scattering, virtual displacement mapping (offset, relief and parallax occlusion mapping), realistic water surfaces based on Dynamic Liquid System, Godray effect, b>particle system with particle physics using DX10 Geometry shader acceleration and environmental effects like dust and smoke affected by wind and other forces. I stop the enumeration here. For a complete feature list, grab the Chrome Engine 4 Presentation (PDF).
