Has anyone gotten DirectX 10 working on an 8800 card?

no its not out yet.

I have direct x10 working in Vista with my 6800's....

Seeing as GF6800s physically cannot do DX10, that would difficult. Oh, and even if they could, nVidia haven't released any DX10 drivers yet.
Actually, you would be able to install it, but the 6800s wouldn't use fully use its features. You'd technically have DX10 installed, but it'll run like DX9.

Vista IS dx 10... Dx 10 is not a driver, the geforce drivers are the driver... Doesn't matter what driver I use, in Vista I have DX 10. There will NOT be a DX 9. anything for Vista as of this time. (At least not according to the latest information in MSDN and Technet.)

Most all larger corps by now have a copy of Vista RTM.

OK, my cards cannot make full use of DX 10, but they still work just fine in Aero mode, and have since the Feb. release. 5386, wasn't it?

I've read that Vista will not have dx10 included on launch. Think it was Tom's that had the article.


I will find it, but also, if u upgrade now from the 6600 which has a 64 or a 128bit memory interface, to a 6800 for 120$ or so with a 256bit, and usually 256 mb of ddr3 memory, those laggs will most likely go away.

Thats not too much money to spend, for now, and when dx10 comes out next summer with more than 3 games to play that utilize the dx10 technology you'll have a larger variety of cards to chose from and lower prises.

For those of you who think that having top of the line products 1st for bragin rights is kool. This is for you, video cards dont come out like cars, motorcycles or tvs(50 inch plasma) with all that is needed to run for aleast 10 years. they come out with little support( drivers-beta usually) games need to catch up and usually we the gamers are the research and developement. So havin said that the 8800s with dx10 capable are not also Backwards compatable. DX10 isnt bwc, maybe they'll change it. But the cards are.

Best advise i can give you is, to spend a little now and say til summer 07 to get the best deals on 4x4 amd or c2d-4, dx10 cards and games that use the dx10 technology.

P.S. I think that microsoft will see the need for dx10 on existing XP and be bwc. Why? Cause of the lack of people upgrading to Vista, when its not really and upgrade. People like to stick with what works and I am 1 of them, so until MS shows that Vista is a operating system i cant do without ( like ME to XP) then im stickin with XP.

check this out.

something only ibm has tried before, another thing to think about when upgrading.

To these 'uberclods' it might as well be... I don't have all day to explain the intricacies of Vista's new HAL to newbies that only understand 'plug'n play'...

Back to the point.

Got Vista, and an 8800? If so, any benchmarks yet?

DirectX 10 isnt out yet!

and all the news about it says that it isnt backwards compatible so no existing games or benchmarking software will work with it, also no operating system will work with it. Yet.?

if anyone finds a link that states other wise plz let us know.

One question that has been teasing my mind is this:
Are the unified shaders of the G80s being used in DX9? As in, are the shaders "changing" from pixel to vertex and vice versa all the time, or are they fixed when running DX9? Does anyone know?

What's DX9.0Ex, then?

(Note to everyone: There's no such thing as DX9.0L anymore, it was renamed to DX9.0Ex)

But if you think about it..if the shaders are fixed to something in DX9 mode, you'll see quite an improvement in performance when they become truly unified in DX10.

However, if they're already unified (as in, changing during runtime), then the results we have now don't seem as great.

I think it would still be using the unified shaders to render both DX9 and DX10.

Once I get a P.O cut, I'll be able to add a nvidia 8800 to our lab.... Until then I'm guessing on what the performance will be like. I'm an engineer, I don't like guessing.

Oh trust me, judging by your comments, I've done quite a bit more reading about this then you have...

Yes, and? DXx and my video card do have a relationship. (level of support comes to mind...) Yes, I know the difference between an API and a driver. Nothing interesting in this post. I'll leave you tonight so you can read up on DX9.L/Ex. Perhaps in the morning you'll have something new to talk about.

Yup, same RTsa.

I don't know of anyone else, who would use the same nick.

edit: Considering I've really been digging into Crysis, I've also had to do a lot of research on DX10 and Vista, I do know something.
(then, we have Doc )

I assumed as much. I did a search last night on the word dx9.0ex, and the first link was to the Crysis forum with you talking about it. For those that didn't follow the link, it appears the RTsa is a mod on that forum, with over 3000 posts. Again, if you are a mod on that forum talking about what was rumored to be one of the biggest first DX10 games coming out, I would hope you have a small clue as to whats going on in the DX universe.

I was hoping Croc would have posted something else, perhaps he's still sleeping from his late night reading. Perhaps he'll share some of what he's learned when he wakes up.

I wonder what the difference (in performance) XP SP2's DX9.0c oct and Vista (Final) DX9.0L

Running with a 7900GTO/GTX

i wonder if all this talk about improved Driver/Hardware handling will actuley improve or even affect the currant Generation of Videocards (DX9.0) in anyway!

Could you please enlighten me and tell me what does the Hardware Abstraction Layer has to do with DX9/10, I don't really see how it would prevent DX9 from working. Oh and I am not a newbie so you dont have to spare me the intricacies, links will do, no need to rephrase it . And I am not subscribed to TechNet, get enough spam already.

/Might be DX9.0ex now , but still...

So anyway don't tell people to go read when they are right/partially right.


@RTSa

From the architecture of the G80 and after reading many review I get that the 'load balancing' between the PS/GS/VS is made by the threading engine inside the G80 I don't think it is specific to DX10 bu I could be wrong but I don't see any reason why the hardware itself would not 're-configure' on the fly to accommodate the requirements of the game, be a DX10/9 title

Seeing as GF6800s physically cannot do DX10, that would difficult. Oh, and even if they could, nVidia haven't released any DX10 drivers yet.

(And before you come back "Wawawa, my Vista *says* I have DX10...". I know it does. But that doesn't mean you're actually running DX10.)

Might be moot but here goes anyway, DirectX is an API. It's like an onion with layers, the outmost layer is DX10 and the next layers in is DX9. Your drivers tell your card which layer of the onion to execute. You may have DX10 but a driver that uses the DX9 layer, in which case you're executing DX9 calls. Until you have both DX10, a DX10 driver AND a DX10 card, you'll be running DX9.

Actually its round the other way. Imagine your videocard is in the middle of the onion and the layers go DX10, dx9, DX8 etc. from the inside out, so the outmost layer is the oldest. I'm pretty sure but not certain that the layer (DX version) you use always has to talk in turn to any newer inner layers between it and the video hardware. Thats why DX8 would be slower on a DX10 machine (assuming the same hardware) than a DX8 machine (because it has to talk to the DX9 layer which in turn talks to the DX10 layer which in turn talks to the video hardware).

Dx9.0L is a version of DX9 for vista that I believe has been modified to talk to the DX10 layer as opposed to the original DX9 that talked directly to the video hardware. I believe with DX9.0L its still DX10 which talks to the video card. So its probably slower than the XP version of DX9 which would talk directly to the hardware. Its purpose is to allow DX9 games to run on Vista (not DX10 games to run on XP as The Inquirer originally misreported then retracted).

The driver basically gives the different layers a way to talk to the hardware. A newer driver works deeper in. A DX9 driver allow the DX9 layer to talk to the hardware, a dx10 driver will allow the dx 10 layer to talk to the hardware.
Basically to use DX10 you need the video card in the middle to be DX10, the DX10 onion layer (DX10 itself) and an nVidia driver that would fit directly between the video hardware and the DX10 layer.
Vista RC1 has DX10, but no-one has been able to use it yet as nVidia are only now realeasing their DX10 driver, so first results soon I guess, presuming someone actually has something to run on it, as you also need the game or benchmark program to talk DX10, i.e. is written using the DX10 API.

Well, you can program one yourself.

I think Croc realized he was wrong and he's trying to save himself now. It happens to the best of us.

no, it happens to noobs all the time
