Speaking with Gamingbolt, Dan Baker, one of the founders of Oxide Games, spoke very favorably of the PS4 architecture engineered by Sony, wishing that PCs could have DDR5 RAM as well.
Several high profile developers praised Async Compute, including id Software's Tiago Sousa who said that it was key to hitting the performance target on consoles with DOOM.
Hopefully more devs can put this tech to good use. It certainly showed its potential with DOOM.
There's been stories on how useful it is and the other side of the argument as well. It's early days with it anyway, we'll see how useful it is as more and more use is got out of it.
Sucks for Nvidia. My money is on the fact that Nvidia will come out with "SyncWorks" or some shit once DX12 gets more popular and AMD starts pulling away since they have proper async support. Gotta hold the technology back somehow so their newer (and older) cards that don't properly support async don't start showing their incompatibilities too soon!
Remember these words..."SyncWorks". ..it'll happen.
Edit: Please, if you disagree I'd ask that you explain why as nothing I've said is either false (i.e. Nvidia's async support) or unlikely to happen based on previous company actions (i.e. something like SyncWorks). If you disagree simply because I paint the truth about Nvidia and you don't like it then you can at least admit that as well. Thank you!
Pascal doesn't have full async support. You can clearly see that in the 1080 vs 480 DX12 AoS benchmarks.
No it doesn't. It still can't do compute and graphics simultaneously. It does them separately, they've just advised a way to make switching between the two faster in the pipeline. It just no longer hurts performance like it could with their previous GPU's but it doesn't improve performance either like it can with AMD GPU's.
Here's a good video that shows the difference:

Nvidia is using "PreEmption" while AMD can use true asynchronization.
So in the case of this article and what is being talked about with DOOM Nvidia would, in fact, not benefit from this.
@OoglyBoogly - Actually, the GTX 1080 and 1070 both get a significant boost in Ashes of the Singularity under DX12.
Sure, Async Compute won't yield the same performance boost of AMD, but it should now get a boost nonetheless - albeit a small one.
Nvidia still has no hardware to run Async Compute, it emulates the performance of ACEs through software. The only GPU that supports both FL12.0(AMD) and FL12.1(Nvidia) is inside the XB1.

You sure? It seems like performance with the 1080 in AoTS remains widely unchanged from DX11 to DX12 which is about right considering the type of async it now has.
Ashes of the Singularity developer, Oxide Games, will be discussing their Object Space Lighting technique within DX12, during the GDC 2016.
Well, here is some good news for NVIDIA users. It appears that NVIDIA will fully implement Async Compute via an upcoming driver.
Emulated perhaps, via CPU? I dont know, I dont understand this stuff!! lol
It was only a matter of time either way, and it's time Nvidia can easily afford.
I hadn't taken the time to read a lot of technical info on why Nvidia cards had trouble with this. But I had assumed it should be able to be added via driver. The hardware itself is pretty straight forward, I wasn't aware of anything that should have limited it from doing async.
At this point, it's a software/hardware combo solution for NVIDIA's cards (unlike pure hardware solution for AMD's GCN cards)
I don't fully agree but again I'm no expert in the matter. How I see it though is just like how it works with other components I.e. Memory, cpu etc... It has to be hardware designed so the power runs through the circuitry in parallel. That's how the components are designed in parallel pipelines then how can they run in parallel?
This adding it by a driver update doesn't make sense to me at all. Unless it was already built that way but was purposefully disabled until the point were they could sell it as an extra feature & just enable it in future & they've been caught short. What they're talking about would surly consist of a complete driver rebuild from the ground up from scratch.
Either way, the fact that it's software based means Nvidia controls exactly how much power they allow to their customer depending on which card they buy. Then lower it again in time for a release of a new card with benchmarks that show huge improvements rather than what it actually should of been.
All cards need software i.e. drivers to say how the hardware works and what features are present and available. Not sure why everyone is saying NVidia is just emulating async, can someone explain this fully?
They explain at the end of the article, Maxwell 2 will use a mix of hardware and software whereas GCN uses hardware:
"Maxwell 2: Queues in Software, work distributor in software (context switching), Asynchronous Warps in hardware, DMA Engines in hardware, CUDA cores in hardware.
GCN: Queues/Work distributor/Asynchronous Compute engines (ACEs/Graphic Command Processor) in hardware, Copy (DMA Engines) in hardware, CUs in hardware.”
Yea it's definitely not proper Async, I have a feeling it's not going to work too well in comparison with AMDs GCN native hardware support, can't see emulation matching the real thing.
No one seems to understand that Nvidia just does Async Compute differently from AMD. Hardware support is there, software support isn't up to scratch yet, that's the only async compute "problem" Nvidia users are having right now.
I'm excited to see Oxide's new engine in motion - it'll be interesting to see more RTS games come to consoles. Either way, it's good to see devs excited about hardware!
Wow...a blog post about an article that was already posted to N4G. Bonus points for poaching off of a site as horrible as Gamingbolt. Subby = loser.
The source interview was submitted less than an hour ago. Read that http://gamingbolt.com/nitro...
