DirectX 11 features by DirectX 10/10.1 Graphics card

Say I have Win7 running, can I enable Direct Compute/Tesselation features (i.e. play with it) by DirectX 11 if I have DirectX 10.1 card? (i.e. current nVidia graphics card)

 

No. DX10/10.1 are DX11 compatable but not DX11 compliant.

 

No. Only the 5xxx series cards by ati support DX11 features.

 

DX11 Features, but the other cards most likely can run the DX11 whatever it is that DX11 is lol.

 

Biggest difference between the 5xxx and the future 480 from Nvidia I see is the tesselation.

ATi has a dedicated tesselator core.

Nvidia is doing some voodoo software b.s and forcing it through the general processing shader cores.

ATi leaves the 800-1600 shader cores to do what they were meant to do uninhibited by tesselation tasks.

Shall see how this pans out for Nvidia. If it's good, then great, worth the extra $400? Eh....

 

Ziddy actually its the other way round.

 

I guess we're still in weird transition period where nVidia still yet releasing DirectX 11 compliant card, but the other competitor is already releasing their preliminary DirectX 11 card huh.

 

pretty much, ATI has had theit DX11 since early fall and were still waiting on Nvidia. thy say an end of March release ..... I will believe it then

 

ATI already had the technology to implement dx11 when they released their 4xxx series, but apparently MS gimped dx10(and 10.1) because of Nvidia somehow(I forgot the exact reason, I'll look for the article) so that's why ATI released dx11 compliant hardware way before Nvidia did: they technically already had it.

 

Nvidia GF100 supports DX 11 and is coming soon.
Have a look at the demo:

I'm wondering how hot it'll run, as well as what kind of availability... I'm betting very hot with low availability. ATI already has the 5xxx series in laptops. There's no way Nvidia can touch ATI in the next 6 months to a year.

 

i think dx11 will be a desktop exclusive for quite some time. sure we will have mobile cards that are dx11 capable but wil they actually have the horsepower to run a full dx11 game - and im not talking about a few flags here and there.
tessalation will add 10x more triangles to 3d images and i just cant see any mobile card doing a fully enabled direct x11 game this year. even the ati direct x 11 demo did not have any animated direct x 11 elements, instead it showed a lot static dx11 objects like rocks and statues.
desktop gpus however like the 5890 or upcoming fermi may have the brute strength to run these...

 

Seems like for what DX11 offers in new ways of simulating realism, you need one hell of a rig to run it smoothly. IMO it's not worth it right now if there was any notebooks that fully support DX11, as the current gen consoles will still stick around for at least 3 years because of the console gamers that don't know that they're playing on fairly antiquated hardware with fairly antiquated effects, as DX9 is getting to the point where it can't live up to todays PC gaming standards of shading, effects, and photo realistic graphics. Apart from a game like Crysis.

 

One thing I want to say first. For Nvidia fans I would not worry what happens. Nvidia will find a way to ensure that games are better optimized for their hardware, so no matter what ATi does, Nvidia will somehow win. ATi claimed they will address this issue, but until then, I would not worry if I was waiting for an Nvidia card. Which is very unfortunate in my opinion.

Try again. Nvidia from what I've read does not have a dedicated tessellation unit has ATi as implemented, it's a combination of software and brute forcing it through the shader cores.
- Some of the reviews are very misleading. GF100 does have hardware support for tessellation, but that doesn't mean they have dedicated units just for it.
- I've seen the graphs/demo that Nvidia released and of course we have to realize there many ways for Nvidia to make something run well on their architecture and not run well on ATi.
- I hope both designs will work out fine and that neither is gimped. And hope that game developers stop optimizing games for just one brand. I don't see why they do this for PC and not for Consoles. If they make PC gamers watch stupid Nvidia ads every load screen, why don't they make XBox users watch the same junk considering PS3 does use a Nvidia unit and Xbox uses a ATi unit. That's the reason why I am anti-Nvidia lately, I'm tired of the b/s.

Right there, hardware tesselation unit. Go ATi!

But until we see real game performance we won't know will we? And until ATi actually addresses game development issues, and as long as I have to sit through every loading screen with Nvidia crap, Nvidia will have an edge I think.
