PhysX is going open source, starting today

Whatever the reason we all know it not altruism. More than likely this has something to do with encouraging the adoption of the Turing architecture or more specifically the the Tensor core component of that architecture. Bottom line, they wouldn't have done this unless A.) they would make more money doing so, and B.) they have another suite of proprietary features to gild the Nvidia lily.

So will games have to be designed with this in mind, or will it make it so you can just install the driver and have AMD cards run PhysX on games that already have PhysX (e.g. Witcher 3)?

For most games, in which there is already some level of Physx code already present, it shouldn't require much more than a patch, I would think. Some engines, like Unity already have native support for Physx, so the support on AMD cards should take much.

It would be more of a driver update from AMD than a patch from the dev for the game, wouldn't it?

I’d guess that physx runs so much better on turing than anything amd provides that them allowing amd to run it, thus having them show up in benchmarks against each other, will make nvidia cards look even more ahead.

The motivation here seems to have little to do with gaming. Nvidia is trying to increase their (already substantial) dominance in AI. The improvements they made are specially tailored to AI and robotics research. And the thing is, the AI community has a strong preference for open-source software, so open sourcing it was a necessary step.

 

 

 

The benefit of course, is that if the AI community embraces PhysX, they'll also want to use Nvidia hardware, because Nvidia can make sure it's most optimized for that hardware.
