mobilenvidia Posted July 8, 2011 Report Share Posted July 8, 2011 Just fidding around with drivers 270.41 and 270.45 (making a modded INF I must post) I noticed a post by Gwiz that both drivers are reporting WDDM 1.1 in DXDIAG so I thought I'd investigate this further. I installed Win 8 on my trusty old Dell D820 with it's powerful Quadro NVS 120M (go7400) And found both drivers reported back WDDM 1.0 So back to my desktop try both drivers on my GTX 470 and these both report WDDM 1.1 Now WDDM version is it controlled by the Hardware as 7000 series GPU = 1.0 and 400 series = 1.1 or software ie Win 8 is really only Win 7 with a higher build (as DXDIAG reports) Is build 7989 not ready for WDDM 1.2 yet and reports back 1.1 as this is all it's capable of ? Does anybody with a 500 series GPU get a different result ? Can any one with a 600 series card send it to me to test :) Your thoughts are welcomed Quote Link to comment Share on other sites More sharing options...
