windows 7 ultimate 64bit service pack 1 directx9 issues. after installing service pack 1, wow crashes before login screen in directx9 mode, i have to set gxapi "d3d11", to get wow to launch, and HB only supports dx9 :/. im guessing more ppl will pop up with this problem as they install sp1. so if you found a fix for it please post here =). from what i read it said something about SP1 and tripple buffering or something, but even after disabling it still crashes in dx9 mode. edit: did an uninstallsweep of various stuff, also reinstalled graphics drivers. dx9 is working fine with sp1 now.
