Update: Good news, it will be on video.

It seems Nvidia are getting more invested in Linux, and this makes me rather happy. At SIGGRAPH 2015 on Sunday Nvidia is doing a number of talks, and two are very interesting for us Linux folks.

Between 9-10AM (LA Time) Nvidia will be hosting a "Vulkan on NVIDIA GPUs" talk, and that's incredibly exciting. I now fully expect them to be the first ones out the door with Vulkan in their official drivers. I know Valve are doing experimental Intel drivers, but this is Nvidia doing it officially.

Then at 12:45 - 1:45 pm Nvidia will host another talk titled "The Time Has Come: Powerful Profiling and Debugging Tools Arrive for Linux and OpenGL With NVIDIA’s Linux Graphics Debugger".

It's fantastic to see Nvidia do talks like this, and hopefully they will be available on video somewhere afterwards. Otherwise we will be at the mercy of anyone able to attend, which is impossible for me with a young child right now, not to mention flying to LA + accommodation would be crazy price wise.

I hope to see Intel and AMD talk up Vulkan a bit more soon too.

This has been the single most exciting year in Linux Gaming history, remember it folks. Article taken from GamingOnLinux.com.

Quoting: MyeulCThanks everyone for this information. I have one more question : since DX12 is very similar to Mantle, we can expect it to be very similar to vulkan, right ? Will it make a difference in the porting effort to vulkan ? Or is it something we don't know for sure yet?

according to DICE representative working on Vulkan, porting between the two is trivial since both use exact same approach. add to that SPIR-V (which at least for me is most interesting part) and porting is even easier. SPIR-V is intermediate language and you can create compiler that produces it from anything, HLSL included.

They don't even support OpenCL 1.2, released end of 2011.
Correction: Nvidia supports OpenCL 1.2, while AMD supports OpenCL 2.0
Will be interesting if Nvidia will still lag so far behind with OpenCL 2.1, now that they have to mess around with SPIR-V anyway...

If they didn't change much, we will see that once the final Vulkan documentation is released, the Mantle and Vulkan API has a very large overlap - to the point that most (if not all) Vulkan functions in the initial draft just changed prefixes from gr (Mantle) to vk (Vulkan).

Oh, indeed. Thanks for making me aware of the recent addition!
NVidia supports OpenCL 1.2 since April this year.

However, I don't think they lag behind because of the money involved to support OpenCL 2.0.
It's a political thing. I guess they could rather quickly wire up a OpenCL 2.x interface from their CUDA backend (or whatever intermediate layer there is for the compute stuff).

I think AMD missed an easy opportunity to improve their reputation with the Linux community. Without them Vulkan wouldn't be anywhere now, but they didn't show of anything Vulkan related at GDC...NVIDIA did, Intel did, PowerVR guys did...And now they let NVIDIA come off as the spearhead of Vulkan and OpenGL Linux gaming.

I've been looking forward to Vulkan since it was first announced, but I find it sad that so few people are informed about it considering the positive change it can bring to the industry.

Exactly that!

This one-time chance is not yet gone.
But I agree, a good AMD Vulkan driver must follow quickly after the final spec is released.
Everything points to this year's SIGGRAPH.

Sure, my point was, OpenCL 2.1 and Vulkan using the same SPIR-V intermediate language could lead to interesting synergies, like mayor 3D programs (or even games?) using both, support of better debugging and compiling tools (like LLVM) or some other crazy stuff no-one considered until now, raising the importance of OpenCL for the big business market (still dominated by CUDA). CUDA wont go away, but maybe OpenCL could get a big enough market share for Nvidia to take it seriously.

IMHO the interesting point of the new APIs (Mantle, DX12, Vulkan) is, that they were mainly made by the industry, folks from Dice, EA, Valve etc. and not really solely by AMD, Microsoft or Khronos. So the industry IS informed and interested and those are really the people that count, no need for extensive PR trying to convince these people this time
Users will mostly simply use the best API that their Application/Game is defaulting to.
Maybe this will be DX12 for Windos 10, but I suppose/hope that there will be developers considering Vulkan at least for Windows Vista/7/8 customers (and Linux/mobile naturally).
Anyway, all new APIs beeing that similar, gone should be the days of wrapper layers like eON and crappy ports using merely OpenGL 2+ (and ignoring AZDO).

Quoting: ZeloxI hope vulkan can and will support sli and multimontor setups.
At the moment linuxs is useless when it comes to sli and gaming with more then one montior.

Sadly.

no, it won't. sli/crossfire is obsoleted by both vulkan and directx12. with those you can control each and every gpu (even if they are from different vendor).

sli like feature in the game will be up to developer, not up to drivers

Aah so simple, directx12 and vulcan already "supports it" kind off? I know u said sli is dead or are heading that way. But if u simplefi the it a bit.
The developer have to press the ON button so I can use both gpus and the reselution I want in there game.

And for me as a user, I will be able to have the option in the games setup menu, to change to a bigger reselution, and thats it. If the game supports more then 1 screen / higher reselution.

This is like the main reason I dont use linux 24/7 when I game.
Sry for my english, been a long day.
