Okay, I did some tests for non-metallic surfaces, used UnrealEngine 4 with some stock PBR textures to have a valid reference:

And in Doom3PBR:

The result is very impressive, shading model looks correct. I suspect the biggest problem is idtech4 lights that may be incompatible here. This light cone/hotspot behaves strangely when you move, and when you get close to surfaces, they become too shiny:

But when that gets fixed, it will look as incredible as in UE4.

In the meantime I'll test some metallic surfaces too.

Metallic surface tests, the results are much better:

There's the light hotspot issue, but again, the shading looks correct, almost the same as UE4.

And now for something a bit different, this page has quite a few resources on D3 rendering, BFG version included, so maybe our @stgatilov and @duzenko can find it useful:
