ATI Runs PhysX With Modified Drivers

Haifa (Israel) - This one did not take long: We already knew that Nvidia is working on a CUDA version for x86 CPUs, but said it would leave a modification for ATI GPUs to others. Eran Badit of told us that he has done it already and was able to get the Nvidia PhysX layer to run on ATI Radeon cards.

After playing with Nvidia’s CUDA SDK and PhysX SDK, Eran apparently got the PhysX layer to play along with Radeon cards. He mentioned that enabling PhysX support on Radeon cards is not particularly difficult, leading us to believe that physics on graphics cards may not so much be a technology problem but a game of politics.

Eran said that he will be offering the ATI PhysX-enabling utility on as soon as he gets his hands on more hardware to check the application on more than one graphics card. We are told that he is testing hardware already, which means that the software should be available "soon".

On his first run, Eran got a 22,606 CPU score in 3D Mark Vantage, enhancing the overall score to P4262. A comparable system without PhysX-support will cross the finish line at about P3800.

We are told that there is currently no relationship between and AMD’s PR team, which means that Eran does not have access to Radeon 4850 or 4870 cards. Check the website for the software to become available this weekend.

    This keeps getting better. So, I expect a standard Physics API sometime in the see-able future.

    DirectX has always been a hardware abstraction layer (HAL) that gives developers the same API that will work on all video cards that support it. Making the PhysX SDK work the same way would be the best solution for game developers, so that they don't have to write different code for the different video cards.

    The fact that Nvidia has developed PhysX to only work on their cards, is not doing any favors for game developers. Time will tell if they are developing PhysX purely for their own selfish interests or actually care about the needs of game developers....
