They are not forcing anybody to use Cuda or Physx, that is the choice of the developer. If you don't like the developer using Physx then complain to the developer.

"What the developers use for a physics engine is up to the developer."

i don't think so.. nvidia pay for using physX---

developers just use what brings the most cash..

"Nobody is blocking them from doing so."

i think nvidia is blocking.

and they pay for max damange on other companys.

"Nvidia also contributes to openCL and probably has the best implementation of it out there along with some of the best documentation."

documentation? can you give me the spec of a gtx480 ?


"They are not forcing anybody to use Cuda or Physx,"

they Pay this is a kind of force the force of the Profit and money-

"that is the choice of the developer."

the choice? i don't think so no other company pays for bullshit like nivida.

this choice just hurts entusers and force them to buy nvidia hardware.

Here you go spouting off wild speculative theories again with out any basis.

Do you know what openCL even is? It's an API. Every single item that needs to be known on how to use openCL is freely available for all and documented.

Nvidia has a team that helps the developer implement it though their "TWIMTBP" program. The same thing AMD has with their "Gaming Evolved" program which entails:

• Technical engagement, including referenceable source code, and access to game builds for competing vendors
• Developer tools
• Product development
• Lab testing
• Marketing programs
• Support and integration with our partners

Same as nvidia.

One thing as well, where nvidia is concerned, OpenCL is a layer on top of the CUDA driver interface. Without Cuda, no openCL on nvidia, C for CUDA and OpenCL are simply two ways of accessing the capabilities as is DirectCompute, another vender specific, albeit software vender this time and AMD supports it as well. So it looks like AMD is "feeding" and other "evil empire" and supporting it as well.

Can someone post a short walkthrough on how to install the dependencies so I can run these Phoronix tests?

On Ubuntu 10.04 that is.

Still there is o state trcker for OpenCL on Gallium3d?
