How do I add this registry key to wine: [HKEY_CURRENT_USER\Software\Wine\Direct3D] "UseGLSL"="disabled" As it says to do at http://appdb.winehq.org/objectManager.php?sClass=version&iId=9432? In order to get Portal 1 working. When I open HKEY_CURRENT_USER\Software\Wine in regedit there is no Direct3D. I tried making a .reg file containing the line "UseGLSL"="disabled" and then I clicked the import option in regedit and selected the .reg file but nothing happened. I also tried creating the folder Direct3D in HKEY_CURRENT_USER\Software\Wine\ and giving the default a value of "UseGLSL"="disabled" but Portal still crashes when I make a portal. Does anybody have any ideas? Any help is greatly appreciated :D
