Changed Fallout3.exe and FalloutLauncher.exe to disable Visual Themes, Desktop Composition, DPI settings and Run as Administrator.Set Compatibility Mode to Fallout3.exe and FalloutLauncher.exe both Windows XP SP3 and Windows Vista SP2.Updated drivers to latest 10.10 from ATI/AMD.UPDATE: I tried also the following things but STILL no result My config: AMD X3 720 - XFX ATI HD 4770 - 4 GB RAM - Windows 7 32-bit Re-downloaded the whole game content two times(!).No other messages than the generic Windows 'Application stops working' dialog. Fallout 3 GOTY crashes as soon as I try to create a New game, while Fallout : New Vegas crashes immediately after first video. I have a problem with Fallout 3 GOTY and with Fallout : New Vegas, both Steam version.
