AMD: Nvidia PhysX Will Be Irrelevant

ATI-AMD Comments On Nvidia’s PhysX Decision

AMD does not consider the lack of PhysX support on systems that feature ATI Radeon graphics processing units (GPUs) a problem. At the end, says AMD, PhysX application programming interface (API) will simply become irrelevant in the future.


Advanced Micro Devices, the world’s second largest developer of x86 central processing units (CPUs) and a leading designer of graphics processing units, said that it hardly regrets about Nvidia Corp.’s decision to disable support of hardware physics effects processing using PhysX API and GeForce GPU or Ageia PhysX PPU in systems where ATI Radeon graphics card is used for graphics rendering. In fact, AMD believes that with the raise of popularity of DirectCompute and OpenCL APIs, proprietary PhysX will soon vanish into oblivion.

“Physics can be a good thing for gamers, but it should be for all gamers. When it’s available for everyone, game developers will be able to make physics an integral part of gameplay, rather than just extra eye candy. This requires a physics solution built on industry standards. That’s why DirectX 11 is such a great inflection point for our industry – DirectCompute allows game physics that can be enjoyed by everyone. There are several initiatives (some open-source) that will deliver awesome GPU-based physics for everyone, using either DirectCompute or OpenCL. Industry standards will make any proprietary standard irrelevant,” said Neal Robison, director of global independent software vendors relationship for AMD, in an interview with Icrontic web-site.

Besides, the representative for AMD also accused Nvidia of not acting in gamers’ best interests: disabling support of both GPU- and PPU-based hardware processing of PhysX is not something that helps end-users.

“There’s a real discrepancy between what Nvidia says, and what they do. They “say” that they are looking out for gamers’ best interests. However, decisions like this are the exact opposite of gamers’ best interests,” added Mr. Robison.
