    I just found out that the 266.35 beta drivers allow you to run wow in DX11 without it crashing on startup. This allows full water and sunshaft effects to work.

    First download and install the drivers from here:
    http://www.nvidia.com/object/win7-winvista-64bit-266.35-beta-driver.html

    Second select DX11 under the advanced tab of the graphics options in wow. There is no need to change the config file anymore.

    Finaly restart the game and enable sunshafts and full water settings.

    The game seems to feel a little smoother than it did running in DX9 as well. I would like to give credit to the person who found this out on the wow forum but i can't find the thread again to get there name. Here are some screenshots of it running on my R2.

    Are you sure about that? It is working flawlessly for me.

    edit: I see what you mean it only shows in the filename. I will change the link now.

    DX11 is deisnged differently than the older versions of DX. They made it backwards compatible with DX10.1, DX10 and DX9 hardware. You can't use things like tesselation without hardware support. But you can still enjoy the more efficient API on a dx10/dx10.1 card. This also allows older cards to use DX10/DX10.1 technologys without having to use DX10 which is a terrible performance hog(the reason most games are DX9 and DX11 only now).

    An example of this is DX10.1 ATI cards starting with the HD 2000 series have always had support for tesselation.

    Ahh, makes sense. I kinda figured that DX11 was somewhat backward compatible, but its good to know. Thanks! And yeah, I've noticed that. I havet seen a DX10 game recently. Even Crysis 2 is DX9.

    This seems to work with 267.76 driver as well; however, it makes the screen fuzzy almost as if the refresh rate is set to 50htz. Even though it is not.

    The fuzzyness could be the sunshafts effect. I noticed it seems to add a slight blur/grainy effect to the game.

    Edit: If anyone else finds a driver that works please post it and i will add it to the first post.

    That would be a negative, its just fuzzy no matter what I change. The water is still there though. I think Ill just go back with DX9 until they patch it. Good thread though :)
