I UNDERSTAND!

again you are completely ignoring SOFTWARE! game/DX12 (and i forgot) DRIVERS!

So as i told you a dedicated async card is totally useless because it will gonna help the card itself. No other cards that lacks async capabilities.

You either split the work before you send the data to the gpu so you send graphics to one card and compute to others (This is not async by the way) or you send all the work to the card and then the command processor split the work . Then based on the idle resources the card can use with async the idle workers. There isnt a magic solution to dx12 to work around this. I will leave this conversation here because i think there is no purpose anymore tot his.

PhysX on the other hand is middleware. Meaning, it's proprietary software that has been locked out from working on all other architectures. ASC has not been locked out and cannot be locked out for anybody since it can be made to work in different ways.

GameWorks as a whole is like PhysX. A proprietary middleware that locks out anyone else from using its features. The Gaming Evolved program is NOT the same, because it encourages the use of new techniques, that are later made open source for EVERYONE to use, just like TressFX turned into PureHair in the new Tomb Raider, which works for both nVidia and AMD cards. GameWorks does NOT allow anything like this, since all the effects stay as proprietary ownership of nVidia. HairWorks is still only adaptable by nVidia, and AMD is never allowed to optimize for it.

That is why it's different. And that is why nVidia is bashed and AMD is praised.

I am fully aware of what ASC is, and if you want to get really specific, Nvidia offered to get AMD on board with the Phsyx train, and AMD turned it down. But people don't remember what happened a few years ago.

The fact is, for all intent, AMD is pushing ASC as their exclusive feature, just like Nvidia pushes Phsyx. Right now, regardless of why, ASC and Phsyx are both features that are "exclusive" to each side. Except on OCN one is OK, the other isn't.

EDIT:

Oh, and Nvidia is most certainly barred from touching Gaming Evolved source code. Gaming Evolved is not some open, mystical, platform that everyone runs around hugging in. It is literally just as closed as Nvidia.

I'm not saying that any of that actually has anything to do with Gameworks but when Nvidia markets Gameworks games and then they turn out terrible, it makes them look bad.
One is a standard feature of a cross-vendor API (DX12) and the other is a proprietary SDK developed by a single GPU vendor. Everyone can use ASC (Even Nvidia uses a software implementation) but only one vendor can use Physx.

Nvidia has nothing to do with the shoddy developers and their quality of work. Nor does AMD have anything to do with a shoddy developer, and their quality of work. Outside the specific programs to each vendor, as being discussed.

GameWorks features aren't breaking games, terrible business decisions at the developer are.

GimpWorks is a black box for AMD. They can't optimize it for their GPU's. That is a BIG difference compared to a DX12 feature, which ASC is. Nothing is black boxed there and closed to one vendor or another. It's just that AMD was first to implement it.

Actually this is wrong. Fermi uses a hardware Sheduler quite similar to the GCN's one.

You can check it here.

That is the double standard I am talking about.

Had this been a GameWorks thread/feature discussion, it would have been flooded with "GameWorks! Get that crap out of here, ruining and tubing games!". Yet, here we are, discussing an ENTIRE article about AMD's Gaming Evolved, and people (you) are trying to say it is just about ASC.

No, this is an announcement by AMD and IO of their partnership via the Gaming Evolved program, literally. Let me show you....
This is a Gaming Evolved announcement, and people are going spastic over it, yet with Nvidia they would be burning torches. Further, and I want people to actually think about this...

ASC v.s. Phsyx: Both are features that one can use, but not the other, so why is one OK?

You have got to be kidding right?

Comparing ASC to PhysX, really?

I know right.

Although you would forgive someone who has, based off the language AMD has been using to push ASC. They have claimed, and I quote;

"Hitman will leverage unique DX12 hardware found in only AMD Radeon GPUs"

AMD is completely riding the idea that ASC is "unique" and "only" on AMD hardware. They are going to push it as their thing for as long as they can. If they want to wave the flag, then they too will carry the burden.

As of right now you have a situation of AMD having support for a "feature" that Nvidia doesn't, just like Nvidia currently has ones that AMD doesn't support. Yet here on OCN, one is OK, while the other isn't.

You know it is not the same thing at all. Take your green glasses off. Physx is closed and only allowed to run on Nvidia hardware. ASC can be run on Nvidia, but Nvidia chose to limit that on their cards for some reason. The fact that AMD is going to take advantage of Nvidia's decision is a good business move and there is nothing wrong with it IMHO.

FWIW thanks for trying to be helpful. if it turns out i'm just being stubborn - well it wouldn't be the first time. tongue.gif

Dont worry. There is a lot of misinformations or at least not entirely correct info about the tech and i am trying to help redface.gif But either way if i was a bit aggressive i am sorry.

Basically it means that software will be limiting hardware a lot less than before, and AMD's more powerful hardware will finally be used like it's supposed to.
