NVIDIA have now made PhysX open source

Posted by , | Views: 11,546

Popping up a little while ago on Twitter, NVIDIA has announced that they've now put PhysX under an open source license.

Something I am sure many game developers and the open source community will approve of. Writing about it on their official blog, NVIDIA said "We’re doing this because physics simulation — long key to immersive games and entertainment — turns out to be more important than we ever thought.".

Originally from NovodeX, which was later acquired by Ageia and then in 2008 Ageia itself was acquired by NVIDIA. Instead of focusing on a dedicated expansion card, NVIDIA decided to work with it together with their own GPUs.

You can find it on GitHub under the BSD-3 license. It's good to see NVIDIA do more like this.

soulsourceNevertheless, I just recently installed it via the unofficial Gentoo ebuilds, and I must say, that it indeed ROCks.
Just got me a RX 580 and was sad to learn that I can't use ROCm because ... they think my i7 2600k Sandy Bridge is too old!
So OpenCL on my GPU does not work because of my CPU
That leaves me with Clover and OpenCL 1.1, worse than with my old Nvidia Card before, not exactly what I was expecting...

To be fair, it's not that they "think" it's too old, it lacks a feature required by ROCm on older GPUs. If it were a Vega GPU, it would work with that CPU ( ).

Probably it would be possible to work around that lacking feature though. I guess that they simply don't have a budget for that...

Hope that proton and wine will get proper support for it now.

I think a heartfelt "holy shit!" is appropriate here.

Just tried Tom Clancy's Ghost Recon: Advanced Warfighter 2, one of the games I know directly support PhysX. It doesn't actually work under Proton. Well the game does, the PhysX portion does not.
