You mean the version I linked on Sim-Outhouse forum?
It is not ready to be "playable" anywhere, not for CFS3, not WOFF/WOTR.
It is just an incomplete "tech demo" version for CFS3 modders to try.
It doesn't have 3D clouds (and even standard 2D clouds), fog/haze, dynamic lights, reflections, it has only some minimal shadows, etc.
Visually it is not even close to DX9 shaders you have in WOFF.
