The question should be is NVIDIA supporting FreeBSD yet?

And the answer is so far not. And likely it won't happen, they are supporting Linux because it is a large enough target for their scientific customers, FreeBSD just does not have the market share there.

NVIDIA actually releases their proprietary GPU driver for FreeBSD! Has been doing that for a long long time. Also for Solaris.

Yes, but that's not CUDA, just the basic acceleration.

For CUDA supported are Windows, Linux, Mac OSX

Yes, and "is NVIDIA supporting FreeBSD yet" sounds like "do they have anything for FreeBSD at all"

Right, but the thread here was: "Does freebsd support CUDA yet?" and that was the wrong way around.

So all this in the context of CUDA. Sorry for messing that line up.

Is FreeBSD supporting the Linux binary-blob format yet?

Not for drivers, of course

If the FreeBSD and Linux groups could agree on some kind of standard for binary-blob video drivers, the world would probably be a better place.

Even better if there were open-source drivers, but you know, baby steps.

Agreeing on a kernel ABI? ha ha not gonna happen :D

There are open source drivers. Only on nvidia they (nouveau) are seriously worse than the proprietary ones. For Intel GPUs, the open source driver is the only driver. For AMD, there are some proprietary drivers but they are becoming obsolete, the fully open amdgpu stack is getting better and better all the time.
