[citation][nom]alyoshka[/nom]That's just something they needed to do to survive since OpenCL has ended up being supported by all the major software & hardware firms, [/citation]
What are you talking about? First of all, what OpenCL applications are you referring to? I'm not aware of very many, and no, they haven't been widely adopted. As of now, CUDA is by far the most widely adopted parallel computing architecture.
[citation][nom]alyoshka[/nom]whereas CUDA is still proprietary to NVIDIA and OpenCL doesn't seem to run as well on Nvidia as on ATI stuff, so .........the step.[/citation]
Wow dude, you really sound like you know what you're talking about. Nvidia provides full support for OpenCL and did so before AMD. In fact, one of the few OpenCL applications I'm aware of, SmallLuxGPU, seems to perform significantly better on Fermi based GPU's, especially gf100/110.

Yes, CUDA is proprietary, but given Nvidia's market share relative to AMD's in GPGPU computing, introducing a proprietary standard really isn't much of a problem.
If you're just going to spam baseless AMD fanboyism in the hopes of deceiving the ignorant, may I suggest...
