Solved DirectX 10 or DirectX 11?

[Ravi5kumar]

Hey, I am bit confuse about which version am I running Direct X 10 or Direct X 11.:sarc:

Here is my Direct X Diagnostic Tool report:

It says that I am running Direct X version 11.

Now when I open Windows Experience Index and click on 'View and print detailed performance and system information' a report is generated and it says Direct X version 10.

So can you tell me which one is correct:huh:?

Yours sincerely,
Ravi

Hi Ravi,

They're both correct. Windows 7 comes with DirectX 11; however, your graphics card is DirectX 10.1. For all intents and purposes, despite Windows containing DX11, everything you do game wise is DirectX 10.

Hmm, that's curious! My graphics card (EVGA GTX460 SC) is supposed to be DX11, but the WEI shows that it is using DX10. Why would that be?

 

[Fumz]

Where is wei showing that?

 

[seekermeister]

Just like in the OP's screenshot.

 

[Sardonicus]

Run GPU-Z.
What does it say?

 

[Ravi5kumar]

Run GPU-Z.
What does it say?

It says Direct X 10.

 

[Fumz]

Just like in the OP's screenshot.

Ahh, yes. I never looked at this screen before. Mine shows up as DX10 here too. I would not worry about it. Either WEI, which isn't known for its accuracy, is getting it wrong or the test is done with DX10.

It says Direct X 10.

Yeah, your card was never in doubt.

 

[Ravi5kumar]

Yeah, your card was never in doubt.

Does this mean that My card has direct X 10 but it supports direct x 11?

 

[Wishmaster]

It means that Windows is Capable of using DX11. You will need a Graphics card capable of rendering DX11 however to use it.


Keep in mind though, that if for example, a game is only coded with DX9, thats what your Graphics card will use.

If theres an option of DX9, or Dx10/11, your card will use the best its capable of. In your case, DX10.

 

[seekermeister]

Run GPU-Z.
What does it say?

Unknown.

EDIT: I'm trying to figure out the rest of the numbers, like the clock speed that it shows, which doesn't match with any of the specs for the card. Is GPU speed = to the core clock, shader clock, effective memory clock or ?.

 

[Fumz]

You're running an older version of gpu-z. I'm on 0.5.3 and all is showing up as it should.

 

[Fumz]

Yeah, your card was never in doubt.

Does this mean that My card has direct X 10 but it supports direct x 11?

No. The GT 240 is a DX 10 compliant card; there is no DX11 support. As Wishmaster said, and I'm soooo distracted by his new avatar , ... where was I? Oh, yeah, until you get a DX11 card you won't be able to see any DX11 effects... either in game or anywhere else.

Having said that, the only place it matters is games. You aren't missing any DX11 Windows enhancements, because there aren't any... as far as I can tell, and this is my 3rd DX11 video card.

Now, over the years I've been unimpressed by the improvements each new DX version has brought... until now. DX11 is really sweet. Add to that the new nVidia driver setting (disabled by default) Ambient Occlusions and oh boy... do games just look sick!

It's been a bug in the WEI since day dot.

Thank you for your information!

Ok.Thanks. Now I understand.

Thanks, that looks a lot better.

 

[Britton30]

Well my GTX460 supports DX 11, but those solitaire cards don't look any prettier.


This is from Tech Powerup with Republic of Gamers skin. I thought it looked nice.

Seeker, there is a newer driver than you have, it's 270.61, dated 4/7/2011.

I have got a radeon 1 gig 6770 which has direct 11 support but I too get told dx10

interestingly GPZ reports unknown for graphics card in the dx box - how does that work ?

As smarteyeball pointed out, DX11 cards showing up as DX10 cards in WEI is a bug that's been in 7 since 7 was 7. Nothing we can do about it; nothing to worry about.

As for your issue with gpu-z, click the link in Britton's post... right above yours. It's the latest version of gpu-z, which will report your card correctly.
