I just tried booting up Fallout 3 for the first time since upgrading to Windows 7 64 bit. I DL'ed through Steam and everything installs fine, the launcher opens, but the game never makes it past the initial black screen. My system is total overkill for this game (Core i7, Radeon 5870), so I know that this is not the problem. I have tried uninstalling and reinstalling graphics drivers, running in compatibility mode, running as admin, install GFWL, and changing the codec settings. Is anyone else still having this problem? Is there a solution out there?
