John Carmack, Id Software Technical Director, always have no special sympathy for dedicated hardware Ageia PhysX.
He called it “bad idea” in 2007, and he didn’t change his mind since then:
“I hope Nvidia didn’t pay a whole lot of money for them” – ended John.
Thankfully, all this negative talk is related to old, dedicated Ageia PPU idea. Carmack still didn’t reveal his opinion about GPU PhysX.
Edit: We can see, that author of this video is now trying to misinform people by renaming this video to “JC on hardware accelerated (GPU) PhysX” while Carmack was talking about Ageia PhysX PPU, without any clear word about current HW PhysX by Nvidia. Don’t be confused.
Edit2: And I get blocked during discussion. It seems that I was right.
