NVIDIA Kepler not fully compliant with DirectX 11.1

Hilbert Hagedoorn

After a discussion on a german a website, Nvidia confirmed that the Geforce 600 series not fully DirectX 11.1 compatible. Well, it doesn't fully support the API.Â*The GTX 680 supports DirectX 11.1 wi...

Who cares, Most game developers arent even DX10 compliant.

Lol your spelling mistakes have been somewhat epic lately.

But it makes sense, the "Kepler" architecture is not even stated as being DX11.1 complaint. But I'm sure many will hope it will be; not that I can see much coming from it besides "Native 3D."

Stuff we won't see in games, makes sense.

If I'm reading that right it means that Kepler supports DX11.1 in the same way that DX11 supports DX10 graphics cards by virtue of being backward compatible. So any DX11.1 games would simply run as DX11 on Kepler cards even though MSI Afterburner (or whatever) would show DX11.1.

I can't say I'm bothered personally as I don't believe many games will use DX11.1 anyway and, if they do, then by that time new NVIDIA cards will be out and I'll have upgraded again anyway. As far as stereoscopic 3D goes, I cannot see it properly so I would never be interested in DX11.1 for that reason either.

yeah 3d gaming and it performance hit = just another way for you to feel shafted by the fact that your $1000+ gpu is inadequate.

at least its nothing like DX10.1 and DX10.0 (hopefully). Lots of game are still using DX9 anyway.

you are sure ?

its even in there page presentation of Kepler, and specially about the interview when Kepler was launched when they was asked about the bug in driver/card id who was showing DX11.0 only

we also had to ask specifically whether the GK104 GPU with DirectX 11.1 support. The answer is yes, but NVIDIA's Drew Henry (General Manager for NVIDIA GPU's PC Business Unit), the "Who cares?"

( this is not really important for me what features are supported on hardware or software and marketing is marketing.. threre's no drama to make about this )..

In reality, Kepler only support DX11.1 features who can be used by the API on DX11_0 hardware level. All DX11.1 parts who are not supported by API and need specially hardware for it, are not supported by kepler

If you look the table on MSDN about DX level features, on the DX11.0 column, the DX11.1 features writed "optional1 " ( mean can be supported by API level DX11.1 runtime ) are supported by Kepler, but if you look the column of DX11.1 hardware, all features who require to be DX11.1 on hardware level, are note supported.. ( UAV on all stage ( used as feature like tesselation ), TIR ( can used on deferred rendering features for allow the use of different resolution table ).

Yet again, DX11.1 features level is not used yet, so.. no drama there.

I wouldn't lose any sleep over it, bring on the 780 I will buy it

It mentions DX11 not 11.1, and the Kepler 'Whitepaper" doesn't mention 11.1 either. http://www.geforce.com/Active/en_US/...aper-FINAL.pdf

Not that any of that matters, it just means they will have to implement it on a software level.

But like you said, it dont really matter. Nvidia have never really insist on this... and we understand why now. But i agree, there's no drama to do with that..

With all the bullsh is writing Nvidia in this kepler presentation page, one less, one more.

Who cares. There's only a handful of games that properly support DX11 right now anyway.

@Lane: Strange, I wonder why Nvidia would mention it on their site but not in the Kepler Whitepaper.

For be honest, im done with this story, its not like it will change anything anyway in close future for 600 series user.. so time to move to something else i think.

IT didnt matter with 10.1 it not gona matter with 11.1 most games stil are on dx9 and the handfull that there are for DX11 are still Console ports of a games based off DX 9 with dx 11 features feeling like a after thought.

Have DX11.1 at this point nothing more then bragging rights on hardware. That wont be used for years if ever. Only way this 11 or 11.1 for that matter will become the defacto standard like DX 9 has been since the consoles came out. Will be the Consoles are DX11.1 or 11 Compliant hardware. I see them possible being 11 Compliant hardware but not 11.1

I've been holding out for the 780 as well.

Really, if we make a list of fully DirectX 11.0 compliant games...there are not so much of them////...... so who cares about direct x 11.1 at this time...... May be Microsoft is backing its Windows 8 sales with directx 11.1....features...

Should DirectX 11.1 be a base model for the new Xbox 720 (actually the 'X' in XBox stands for the 'X' in DirectX), a large part of the power lies with their developers {if they are not using the whole DX11.1 features....then there's little reason to use these features.....}
