I just ran windows update and it showing a 233.6 MB download for nvidia - graphics adapter WDDM1.1, WDDM1.2, and WDDM1.3, other hardware nvidia GeForce GTX 470? It's published 09/20/2013... Anyone know what this is? I'm running windows 8 pro.
That is a display driver for your card that Microsoft have in their update catalog. I did a quick search through the update catalog http://catalog.update.microsoft.com and saw the exact driver you are talking about. The other seemingly identical drivers listed there with different sizes are for different platforms, such as x86. The version associated with it is 1.3.26.4. This is probably a different way of writing out 326.4x (x being something), so it isn't the latest even for WHQL. In fact, it appears the very same driver was listed back in June for the Windows 8.1 preview. The reason why it didn't show up on your list then is because it no doubt just had Windows 8 not in the inf file. The driver date is misleading as that is the date of the inf, the files are probably the same as the earlier June release for Windows 8.1 preview. Ideally though try not to use Windowsupdate drivers unless no later drivers are available. Since 327.23 WHQL (or 327.24 beta) is available, use that instead .
Microsoft have updated their driver catalogue to include Windows 8.1 (WDDM 1.3). The driver is also backwards compatible with Windows 8 (WDDM 1.2) and Windows 7 (WDDM 1.1).
If I recall ,ms had a problem with its updating system till not long ago.I would uninstall the one you got ,install ms version then update this version .sometime ms add stuff not apparent but needed!once installed those usually stay even if you update to latest afterward.
i have recently installed windows 8.1. when i check dxdiag it shows WDDM 1.2. shouldnt it be WDDM 1.3?i have updated graphics driver to latest version.how to update windows display driver to version 1.3?
I like to know as well I 2 would like to know what exactly this Nvidia graphics adapter wddm1.1-1.3 is all I can find online atm is its some sort of possible graphics update for improved gaming performance, and supposedly it allows Windows 7 to use DX11.1 but mostly hear say as everyone is complaining of problems. Thank God it showed up as optional and not for critical for myself, until we know what it actually is and there is a fix PLEASE DO NOT INSTALL THAT GOES FOR EVERYONE!!!! it will **** you PC up and make it extremely difficult to restore your PC to a working state as it uninstalls and or conflicts with your current Nvidia drivers from what I red even system rstore and safe mode have trouble working :thumbdown you have been warned good luck!:bang:
