I downloaded the Fallout 3 Wanderer's Edition along with Mart's Mutant Mod. At first it was working properly for weeks but now and then I would get a crash, due to the multicore issue of the game... at least what I though. So I changed the FALLOUT.INI file with the fix: bUseThreadedAI=1 iNumHWThrerads=2 Afterwards the game would crash on the first minute I played. Could it be problems with Point Lookout? I checked if the saves were corrupt but they weren't. I tried saving the FALLOUT.INI file back to its previous form by undoing the changes I did but that didn't work either. Any way this could be fixed?
