Windows Vista service pack 1 is installed but Direct X 10.1 is not functioning

Mon, 18 May 2009 17:36:11 Z

Hello, this is my second issue with Vista. I have just recently installed Windows Vista Service pack 1, but my dxdiag says that I only have 10 installed. The install of SP 1 appeared to have gone properly (no error reports, when my computer rebooted it said Service pack 1 was installed) but DX 10.1 was not installed. I have uninstalled and reinstalled the service pack but the same issue reappears. I have a nVidia 9800 GT graphics card, which is DX 10 compatible. It is not an issue with dxdiag itself, because when I try to run S.T.A.L.K.E.R Clear Sky which has Direct X 10.1 only features, the Dx10.1 features are locked. Please help, I am QA tester and it is needed that I am using Windows Vista at it's full capacity.

Got the same problem, exactly, even down to S.T.A.L.K.E.R Clear Sky not showing it. And as far as I remember the 9800GT were supposed to be able to handle DX 10.1.
