Independent Programmer Creates Patch to Re-Enable PhysX Support on Systems with ATI Radeon

Even though Nvidia Corp. does not want to enable support of hardware physics processing using its PhysX application programming interface (API) on systems that use ATI Radeon graphics cards for rendering, an independent enthusiast has managed to create a patch that re-enables hardware PhysX processing using GeForce or Ageia chips on “non-qualified” computers.

Last week it transpired that Nvidia had decided 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. Even though few people actually use PhysX PPUs or Nvidia GeForce graphics boards inside the systems with ATI Radeon graphics boards, Nvidia’s decision has caused rather massive outrage by the enthusiast community.


Ngohq.com web-site reports that a forum member by the name of GenL has released an experimental beta patch which intercepts disable-PhysX-if-Radeon-is-present-code. So far, according to user comments the patch delivers successful results. At this stage, the patch only works for PhysX GPU acceleration and not PPU acceleration. Nevertheless, the developer claims that work is still in progress.

Nvidia did not comment on the news-story.
