I’ve been having problems getting Fallout 3, one of my favorite games, to work on Windows 7. After trying all the fixes I could find online without luck, I finally figured out a configuration that seems to work very well This of course is with no thanks to bethesda softworks… they pretty much told me to go frack myself because they don’t support windows 7.
The problem I was having was very frequent freezing and crashing of the game anywhere from one to a few minutes into gameplay. After much fiddling, this is what works for me:
Find your FALLOUT.INI file. Mine was located at “C:\Users\tim\My Documents\My Games\Fallout3\FALLOUT.INI” Once you find it, open it and change the line that says “bUseThreadedAI=0” to “bUseThreadedAI=1”. Right after that line, add one that says “iNumHWThreads=2”.
Next, find your fallout.exe file. Mine was located at “C:\Program Files\Steam\steamapps\common\fallout 3\Fallout3.exe” because I bought fallout 3 on steam. Your location may vary. Right click on “Fallout3.exe” and click on “Properties.” Go to the “Compatability” tab, and select “run this program in compatability mode for:” and choose “Windows XP (Service Pack 3).” Select “Disable Desktop Composition.”
That’s it, you’re good to go. Hope this works. If it doesn’t, don’t ask me any questions, I found this by chance. Good luck!
