Dxdiag incorrectly reports DirectX 11 devices as DDI 10.1 when using Win 7

There is a hard way to get it to work, but it takes ages and is a rather daunting task.

I'm waiting to get East's go ahead to post up something I got from him as a proper guide on the subject. It worked fine for me, but it did take like, 2 or 3 hours and a considerable amount of effort.

A question to you, have you formatted after changing over to your 5 series card? And I'm assuming your previous card was a DX10/10.1 card?

Yes i did do a clean format because i was on 32-bit with my 8800GT but after installing 5750 and manage to sort out my issues with 64-bit i installed 64-bit and installed latest ATI drivers so no there wasn't any old previous drivers from a DX10/10.1 card.
 
Is it right that my gtx 275 shows as dx 11 in dxdiag - win 7 64 ultimate?

Hmm, well there goes my theory :shadedshu Most I could suggest would be to try out that guide I mentioned once it gets posted..

There isn't a DX Version in the Display tab short of the DDI; so the DDI should give the best bet of an accurate DX version, according to my recent experiences with East's thread..
If it's the DX version in the system tab hes talking about, well then that's just showing the OS's DX version afaik.

Mussels mate, I normally appreciate your views and humour but was that necessary? You are right, I'm relatively new to computing and don't understand so perhaps explain better wtf DDI is and we can all start learning a little without the condescending tone:shadedshu:rolleyes:
 
sorry mate... its been a long day.
 
no worries sport :)
 
in the case of DXdiag, its just saying what the max directX version is your card supports.

You can run a DX7 card in XP and have DX9 installed, you can have DX11 in 7 and have a DX9 card installed... DX version is system, DDI is video card.
 
ok, I've updated the OP with some instructions on how to purge your OS from recognizing your old video card. Hopefully that will allow you to use DDI hotfix if it reads 10.1 when using win7 with a dx11 video card.
 
heh i never even noticed that i had this bug, but the hotfix from ms has fixed it - thanks for not only making me notice the bug, but also giving me the link to fix it :toast:
 
Come to think of it, maybe the MS fix only works on driver version # and newer. The bug is in the device driver, not Windows. This would also explain the mess you have to go through to get the hotfix (because it is not something Microsoft should directly patch so they want to know everyone that has it).
 
Can anyone help?

Hi

Just joined today to ask for some advice.

Built my new system mainly for games and music but having issue with DDI not showing 11.

I have done more clean installs of windows 7 in the last week than I care to remember lol.

I have followed the step by step guide earlier in this thread but cannot seem to get it to work. also tried the superb windows hotfix lol, no joy, did check it was the win7 *64 version. removed all Cat drivers and directX and clean installed them, no joy.

Going out of my mind as all id like to do is play Dirt2 and AVP in dx11 will tesselation etc.

Any advice would be appreciated.

unfortunately, you seem to have covered all the steps we know of so far.
 
Thanks for the reply

its really annoying as seems to work for some and not others.

At one point i had it all working including unigine heaven and could switch tesselation on/off and avp let me choose dx 11 features, but after shut down and re-boot next day both of those programs would not even work. i guess all will be resolved in time.
 
update

ok so i got in today not changed specs since last post, got the leaked cat 10.3 driver software and installed it.

the results!!!
without restarting i checked dxdiag, it was magically showing ddi as 11! hurray but...

i ran avp, it was letting me use dx 11 upgrades like tesselation etc, but ran very bad, jumpy etc, i also ran dirt 2, i could now set post processing to high, game ran ok but still quite jumpy in places. i did restart to see if it would fix...

after restart ddi was back to 10.1, and i can now not run avp at all, just says avp has stopped working, but i can still run dirt2 but cannot get high post processing again, only medium, so its clearly running in dx10 mode again!

does this help any more expericanced members than i work out where the problem is???

thanks
 
New Guy, I get the impression that your Registry somehow became corrupt or missing something. Unless you've got a backup of it that dates before the problems occured I can only suggest a reformat at this time.

Furthermore, the only reason I know of why DDI won't show version 11 is because your OS is still recognizing something else (usually in the registry somewhere). If there is another reason why this is happening as Mussels suggested we've given all we know to help resolve the issue, sorry.

However:
I am curious as to what drivers are used once you uninstall your Cat drivers. Could you post back with that information by uninstalling your drives (just the CCC unisntall will do). Reboot, then go to Device Manager, Display Adapter. What's found in Display Adapter?
