Eran Badit of NGOHQ.com has already made some considerable progress
to run on AMD hardware, and it looks like he's now getting a helping hand from a somewhat unexpected source, with NVIDIA itself reportedly giving the project its blessing. Apparently, NVIDIA has even gone so far as to invite Badit to join its developer program, which gives him access to documentation, SDKs and, most importantly, direct access to hardware and NVIDIA engineers, a move that Badit describes as "impressive, inspiring and motivating." Badit is decidedly less impressed by AMD, however, which has apparently been unwilling to provide with any hardware or support for the project. That stubborn stance, he surmises, can only be due to AMD's backing
of Intel's Havok
physics engine, which NVIDIA would no doubt like to have out of the picture (hence its willingness to help here).
