Here are the latest screens of a simple test level I made being rendered with my Iridium Engine and the A7 engine. All lighting is 100% dynamic and requires no pre-calculations of any kind.

There is also no constants used in rendering - for example, the areas of shadows that are brighter or darker are calculated in real-time based on real-time radiosity lighting from the sun.

You can also see physical volumetric lighting and HDR tonemapping with automatic exposure control.

The demo runs at 120 fps at 1024x1024 resolution on my machine (see my signature for details).

oh, and I'm aware that the shadows and bump mapping suck - I didn't bother blurring them or adding real bump mapping because I was only focusing on the global illumination for this demo. There is also no specular term.
