Maxwell does not support Asynch Compute in DX12

Ok, my friend just messaged me with this reddit:
https://www.reddit.com/r/pcmasterra...st_rpcgaming_nvidia_gpus_do_not_support_dx12/

......what happened and does that affect mobile maxwells too?
Don't know if this has been posted already, but this seems ridiculous for nVidia.

 

Did you bother to read a little farther down in that thread? Specifically the responses of Robert Hallock from AMD.

He even addresses what DX12 features the GCN architecture lacks support for:

So there you have it. There is no graphics card on the market that fully supports DX12. Cut Nvidia some slack here.

It isn't exactly new news. That article was dated July 30th.

 

"DX12 support" is also still pie in the sky hype at this point. If Micro$haft keeps using Windows 10 as a hatchet to take a big old dump on desktop and laptop hardware and screwing things up the way they have been, no self-respecting game developers are going to burn calories on DX12 if it only functions on machines running a turd OS product just because Micro$lop is making a big deal about it. Windows 7 still dwarfs 10 and, while it looks successful based on all of the marketing hoopla, the numbers may not change in light of the problems with 10. On top of all that, the imbeciles in Redmond apparently don't know the difference between an XBOX One and an enthusiast PC, or the people that buy them. PC enthusiasts don't waste their money on XBOX. It only stands to reason that we are all hoping there will be a miracle cure for the severe case of stupid that surrounds us. Unfortunately, there's not one and the disease is fatal.

 

Yes, but right now is the first time we cared enough to notice it

 

Major difference being AMD came to the thread and pointed out what they don't support, while nVidia lied and said "full DX12 support", won't even care to respond to owners on the thread, and then pulled that shady number with telling the oxide devs to disable DX12 features in a DX12 benchmark. More than a little sketchy, don't you think?

 

Source?

 

Source: their lips moved... status quo. And, they're in good company... big tech is just like politics... run by liars and thieves. Whatever it takes to sell whatever they're selling.

 

I want to know because the reactionary gaming community loves to take things out of context and blow them out of proportion. Case in point: This thread. Maybe being 21 I'm just too old, but this sort of confusion-spawned cluster happens every time there is a new API. It happened with GeForce FX and DX9, it happened with R400 and DX9.0c/SM3.0 HDR rendering, it happened with Tesla/R600/R700 and DX11.

 

Yeah, I know. People just want something to be excited about. I guess that's better than the alternative. I'm over 50 and I'm not too old to get excited about something awesome. But, to your point... I'm not seeing anything that rises to the level of anything that even remotely resembles awesome to me right now. No new CPUs, GPUs, OS, API... nothing from NVIDIA, AMD, Intel, Micro$haft... Just a lot of silly stuff saying "buy me, buy me" LOL... but, no, nothing really that qualifies as amazing.

 

Straight from the nVidia blog: http://blogs.nvidia.com/blog/2015/01/21/windows-10-nvidia-dx12/

"We’re more than ready. GPUs built on our Maxwell GPU architecture – such as our recently released GeForce GTX 970 and GeForce GTX 980 – fully support DX12."

Guess that was a lie.

There's no news, people.

Every recent graphics API you have every worked with is partly supported by any device you have owned. And you know what? Out of the features that are exposed by the drivers, only a subset is actually calculated by the GPU. The others are handled by software. (The most well known example is GeForce vs Quadro and Radeon vs FirePro in OpenGL.)

 

So lemme just put this here...

All of you can have a wonderful laugh =D =D

 

Yeah, I get a chuckle out of all the drama around DX12. I had a hunch it would end up being a big to do about nothing, and it's certainly shaping up to be exactly that. My skepticism has been replaced by not really giving a flying fritter about it. It's part of Windows 10 because without that dangling carrot as a lure it would be a dismal failure just as Windows 8/8.1 are. Some people just cannot resist bright shiny objects and are willing to walk across hot coals to get to them.

When I was younger I was always excited about new stuff and optimistic it would be awesome. And, sometimes--not very often--it was. As I have matured and numbed to the hype, I'm finding less and less really warrants excitement and some stuff I might have been excited about 8 or 10 years ago is a good reason to be very skeptical, or even worried about. Where we (almost all people) tend to go astray is in the assumption that we are actually valued as customers. News flash... that's a lie and we are all nothing but revenue streams for greedy tech peddlers that don't give a rat's tail about us. They are willing to say or do whatever it takes to get their target market to open their wallets, even if that means using lies and deception to keep the cash flowing.

 

Progress does happen. Think about where we were, say, 8 or 10 years ago. If PR hype and lying could get the job done all on its own we would never get into industrial age. The problem is you never known which is the real jump and which is salesman's story until it actually pans out.

Since we don't have crystal balls, before that part of history called "DX12 adoption" (or possibly the absence of it) happens, all we can do is speculate and discuss with the limited information available. Better than doing nothing if you're interested in this topic, no?


BTW, the fact that we are revenue streams is exactly the reason they care about us. That includes being concerned about our mental weaknesses as well though.

Interesting... Hopefully this new driver doesn't blow out LCD screens.....

 

There's been several huge threads on various tech forums. The gist is that while inconclusive, it appears that Maxwell doesn't (fully) support async compute at the hardware level, but can emulate it at the driver level. Although that incurs some driver overhead, it's still better than nothing.

At least this episode managed to get nVidia off their asses and actually do something about it. Oh and coming clean (sort of) a second time about Maxwell.
