Dont you mean "advocates and lovers of proprietary standards, in spite of the open ones.?
AMD Mantle API [updating]
- Thread starter MarkoIt
- Start date
Its relative and comparative, compared to amd users, nvidia users have less performance.
It's not and we would prefer if that ran on amd gpu's as well.
Just sayin
That developer is saying that true multithreaded command buffer submission support would go along along way in helping PC match consoles in terms of draw call efficiency. He's not talking about D3D's multithreaded submission model, which could never achieve that level of efficiency due to way it works (D3D doesn't support direct memory access or low-level synchronization functions).
But not less performance than they (we) would have if Mantle didn't exist so what have they (we) lost really other than bragging rights in those games that Mantle supports? We still get the frame rates we would have got regardless of Mantles existence.
and lower frame rates than you would have got if mantle ran equally well on nv hardware
That's still nowhere near negatively impacting Nvidia users.
Dont think so. he's being very specific. Supporting Driver Command Lists in DirectX will get you 70-80% of next-gen console performance in terms of submitting draw calls to the hardware
In absolute terms your correct in relative terms however... it depends on point of view
Believe me if that were the case it would have been released.
yes, correct
I believe that mantle is the biggest news in the world of PC gaming as the consolidation of directx as reference API (for all we know, can not wait to learn more at APU2013), it is obvious that this generates a strong discussion, between proponents and detractors, even and especially when they are not agnostic.

So it is bogus then...
/me slaps the lead dev of pcars
In his defense, maybe he was simply making the mistake of assuming it would work as intended
Are you suggesting that Johan is investing his time and energy into a gimmick meant to sell more AMD GPUs? Why on Earth would he do that?
No one can say what will happen, but what might happen is Mantle pushing improvements into open APIs, and also increasing competitive pressure which could lead to price cuts or increased efforts from competing offerings. That way you could benefit even if you wanted to buy a different GPU.
I'd like to point out that I said not all proprietary APIs are bad. Everything has pros/cons; I prefer D3D over OGL, but I can still acknowledge that D3D has a pretty big con for non-Windows users (and some old Windows users). Trust me, I don't equate "open" to mean the "best".
To respond directly to your example, yeah I think console APIs provide a con for pc consumers. Forcing developers to divert resources away from their platform directly impacts the experience. I happen to think that trade off is more than worth it for developers, but there is a con (to some).
Indeed. There is nothing gimmicky about Mantle, and if Microsoft had done its job with D3D and WDDM Mantle would never have been necessary.
Unfortunately AFAICT Microsoft has dropped the ball with D3D and AMD had to pick it up. I believe as most others in this thread that MS will whip D3D into shape now that Mantle is in the picture. In the mean time AMD deserves every competitive advantage it will get from this.
Exactly. The existence of Mantle doesn't imply a worse experience for non-AMD users. However devs do have limited resources and Mantle is yet another thing they have to deal with...
I do not know, you tell me.
I know that to solve some limitations related to programming on pc has chosen proprietary API that benefit only to AMD's vgas. And the gimmick is of AMD, that is a company...or do you think is a charitable foundation?
