NVIDIA extends PhysX for high fidelity simulations, goes open source

NVIDIA PhysX, the most popular physics simulation engine on the planet, is going open source.

 

We’re doing this because physics simulation — long key to immersive games and entertainment — turns out to be more important than we ever thought.

 

Physics simulation dovetails with AI, robotics and computer vision, self-driving vehicles, and high-performance computing.

More likely: we're doing this because no one wants to use PhysX anymore

PhysX will now be the only free, open-source physics solution that takes advantage of GPU acceleration and can handle large virtual environments.

 

It will be available as open source starting Monday, Dec. 3, under the simple BSD-3 license.

I wonder how it will treat GPU acceleration on other vendors than NVIDIA

open source is good. well done nvidia. 

[schwellmo92]

The damage has already been done and now no one uses it, so only now they release it? Good job, I guess..

better late than never right?

it's open-source and computed with CUDA cores only, so no reason why stream processors can't be 'taught' the computing.

Better late than never i guess...

Question is if AMD will end up supporting it now. Not that there is any point in them doing so but i dunno...

[DeScruff]

Remember when some people ran a ATi/AMD graphics card, and had a secondary Nvidia card for PhysX?

[JoeCoke]

Maybe things would be different if they did this... Like 10 years ago.

 

I mean, it's still a good thing that they're doing this, but come on.

nvidia doesn't seem too intelligent. They're like people who think old, dead memes are still funny and relevant when nobody likes them anymore.

Well, companies tend to not make things open-source when they're still profitable. Much harder to control their product and I believe it introduces issues with copyright or something (I am not a lawyer, it's just what I've heard).

 

yeah, I guess, since thats kind of what Android is built off of (but fcking huawei won't let me root my phone!)

Now.... If only someone could find a way to make PhysX effects on Borderlands 2 work on AMD cards

If it's a CUDA-only feature, ye, then nVidia can fuck themself in real-time physics. Gamedevs won't waste their resources on something that's been dead the past 10 years.

not in this case. Nvidia is very bad company AMD opens everything Nvidia closes and opens when nobody needs it anymore.

Open source gsync incoming in 15 years.

Everyone in the thread claiming physx is dead is wrong. They just stopped pushing the GPU compute version, games still include the physx cpu libraries. This is good news, maybe we can see the return of gpu physics?

While this would be nice, I also wonder how much DirectCompute and OpenCL take over the role.

Lol just after Digital Extremes coded their own physics simulation for Warframe because PhysX was no longer supported

There's also the factor that starting mid next year we're expecting the consumer cpu core count to be up to 16. It may just make sense to optimize the CPU physx libraries and try to bring them to gpu quality levels instead of bogging down the GPU itself and just use some idle cores

and it runs better than when they had Physx. I always had that setting turned off anyways but now it a different story (Still have it off in the switch version)

i never said nvidia is a good company when it comes to open-source. i just said it's good that they made something open-source.

Actually PhysX never died in anyway. Somewhere around 2010-2012 Nvidia shifted developing only PhysX SDK and moved all of the resources from making PhysX for games to develope the APEX branding which has lived very much in the shadows of Nvidia Gameworks (APEX clothing, APEX destruction, APEX vegetation, APEX hair and so on). Around the same time Nvidia changed PhysX for other applications to be Nvidia FleX. So basicly PhysX never went away, it was just rebranded.

 

I think this is good thing that Nvidia brought PhysX back as open source. Maybe now even AMD gets some kind of PhysX support, because earlier AMD didn't let Nvidia develope PhysX or other CUDA technologies for AMD GPUs, because reasons (one tinfoil aht reason why Nvidia stopped marketing PhysX and moved it as APEX under Gameworks). Now there's at least some kind of hope that someone somewhere does this and maybe even more. Even if the PhysX stil ltakes a lot of use from CUDA and it was "locked" to Nvidia cards, it was still very interesting and exciting piece of technology and it's nice to see that it gets another life appart from the offical APEX and FleX lines.

Now make DLSS open source
