AMD: PhysX and Other Proprietary Standards Will Die Off

Paul Lilly

The promise of in-game physics has yet to be fully realized, but the technology doesn't appear to be going anywhere. Leading the charge is Nvidia, who has a vested interest with its acquired PhysX technology. But in an interview with Bit-Tech, Godfrey Cheng, Director of Technical Marketing in AMD's Graphics Product Group, downplayed the proprietary standard.

"There is no plan for closed and proprietary standards like PhysX," said Cheng . "As we have emphasized with our support for OpenCL and DX11, closed and proprietary standards will die."

The comment came in response to questions about EA's and 2K's decision to license Nvidia's PhysX technology across all of their worldwide studios. And while Cheng said he can't comment on competitor's business models, he did say that AMD views "Havok technologies and products to be the leaders in physics simulation," pointing out that game developers share that same view. If true, it would be reasonable to assume EA and 2K have gone against their development studios' wishes by adopting PhysX.

"People need to scrutinize various announcements on what is beling 'licensed,'" Cheng pointed out. "Is it to replace the whole physics simulation / tool stack within a game or within the whole studio? Is it for a specific physics simulation product or just a couple of titles? Remember PhysX also has game physics libraries in addition to its new GPU based products."

Cheng went on to say that Havok physics on Radeon videocards is still forthcoming, possibly by early 2009, but noted that this is just the beginning of in-game physics.
