Have a DX11 compatible card, but DX11 is greyed out in the Graphics Options (SOLUTION: windows updates)

[Jayzilla]

Hello everyone. I've just solved a frustrating S2 ctd issue by installing Vista SP2 (Previous thread *HERE* contains system setup and pre-SP2 DXDIAG).

However, while the game runs smoothly, I have yet to see the DX11 wonder-graphics, and I would like to. For whatever reason, when I mouse over the 'dx11' option in my graphics settings, the button is greyed out. DX9 is my only other option (not sure why it doesn't show dx10?).

It gives me a tooltip that says that 'DX11 is not compatible with your current graphics card', even though I'm sure that my Radeon 6870 *is* dx11 compatible. Is there some kind of setting I could change behind the scenes in order to enable DX11?

I think it has to do with your OS, I'm not 100% sure, but I don't think Vista supports DX11 natively, I think you can install it though.

I was under the impression that SP2 for vista enabled DX11, but maybe I need to find something to download.

Have you instlled .Net 4 yet?

Have you instlled .Net 4 yet?

Uhh.... don't think so. I was too busy playing the game without CTDs :p

That's where I think dx11 finally comes into play.

The next ctd, install it, run Windows Update, and install sofware options. Its updates will be in there.

[Jayzilla]

alright, i'll run that and let you know if it fixes it.

Running the game in DX9 has been great though now that I've got vista SP2, I haven't had one CTD. Mostly I want to see if DX11 will improve my graphics much

[irishron]

It may improve the graphics but hurt performance. Good luck.

[Jayzilla]

Oooh, I ran windows updates again, hadn't since before installing SP2.

85 updates.

DX11 is available.

Success!

Good to hear. Enjoy the game.
