How is "difficult to implement" a meaningless statement?

>Those compatibility issues already exist in the form of DX or OpenGL drivers, and most games have to face them. Writing a sim in OpenCL would work on both Nvidia and AMD, and even on Integrated GPUs.

With completely different performance characteristics and very difficult to diagnose bugs.

>Many smaller games mighy but most big games do not. And those games with GPU room to spare normally have CPU to spare.

Maybe if you're talking about mainstream AAA single player titles, but many multiplayer titles tend to have CPU limits instead.

>There is - PhysX.

Which only works on nvidia hardware and is thus a useless solution.
