I think this is FPSC with a bunch of new shaders Bond1 has authored.
The clever thing TGC has done is to ensure this time around they are available out of the box and properly integrated with the engines lightmapping and fog system.
Its not clear if this demo is using static or dynamic lights for these effects as there is no visible shadows except for the planar shadow on the character which is a shader Bond1 already released. Looks like they also have a little bloom on there for the lights.
If TGC focus on this tightly integrated graphics approach then focus on things like occlusion culling to get the rendering performance and a new physics and AI system, I agree this could be really good.
I know I keep going on about dynamic shadows but providing Lee extends the work Bond1 has already done to include dynamic shadow support for all dynamic entities that would be sufficient.
It was always a nightmare having to dig all the shaders out of Bond1's model packs and mixing and matching them to get the right results. This is what X10 was missing, a good set of shaders to use out of the box.
