Fallout 3 patch 1 . 1 " Fallout 3 " patch 1 . 1 was released on December 15 , 2008 for the PlayStation 3 and on January 13 , 2009 for the Xbox 360 and PC . It updates " Fallout 3 " to version 1 . 1 . 0 . 35 . The Xbox 360 patch is available via Xbox Live and the PC update can be acquired via Games for Windows Live or the official website . Issues with the patch . Although the patch includes minor fixes , it introduces new issues . Game performance slightly degrades after applying this patch , even when under the same graphics settings as the previous version , as if the game suddenly becomes more CPU and GPU demanding , this seemed bizarre as there were no graphics improvements over the previous version . This drastic degradedness can be noticed even by the players whose specs far exceed the recommended requirements . After applying the patch , saved games will omit several items including and not limited to keys on your keyring on random occasions . Furthermore , the game will have an increased chance of freezing after loading an area . Also , there seems to be a problem with using old save files before the patch ( This issue only occurs with certain PS3 users , but it is not specified ) . The old save files before the patch will not allow the player to save nor auto - save with the new patch installed . The problem is that the start screen after the patch has the word " Save " darkened , which makes it impossible to save with the old save files . It seems to be that the old save files before the patch are not compatible with the 1 . 10 patch . There is no known fix but to delete the patch in " Game Data Utility " and start the game without installing the patch . Some users have reported corrected the issues by performing the following actions : On the Xbox 360 version , Old Olney sewer no longer has the prototype medic power armor . Instead of the two raiders and the Brotherhood of Steel member there are only three skeletons . This seems to be only in certain cases , as some people have reported that the prototype medic armor is still there , even after the patch . Also on the 360 , the patch did not fix freezes while loading certain areas ( i . e . Springvale Elementary ) in save games that had these problems before the patch . In other words , the patch will not fix old loading problems . Loading crashes still occur post patch games as well ( i . e . My Megaton house ) on the Xbox 360 ( restarting console doesn ' t fix crashing ) . This still needs to be confirmed by another person . FWIW , in a play - through started pre - patch , but no visit to Old Olney until post - patch , the armor and raiders were present on Xbox 360 for ( more than ) one user . On the PC version , the mouse acceleration in the main menus , as well as all in - game menus , has become considerably increased . Horizontal mouse acceleration was increased . - on 15 January 2009 a fix for the mouse acceleration had been posted at the official Fallout 3 Forums : For some users with older computers , after installing the patch , the game will fail to start , resulting in the following error message : " This application has failed to start because the application configuration is incorrect . Reinstalling the application may fix this problem . " This occurs only when trying to start the game via the STANDARD method through the Fallout Launcher . Using the Fallout . exe will run the game . However , this method bypasses the initial startup , and makes adjusting settings or using player mods inaccessible . Uninstalling the game and reinstalling results in the same failure , and only opening the disc and running the " setup . exe " will start the reinstall process . Once the reinstall is complete , without the patch , the game will function properly . Re - patching results in the issue to re - occur . ( One possible fix for this . After patching G4W LIVE in game and patching the game . Close the game and open your Fallout 3 folder . C : \ Program Files \ Bethesda Softworks \ Fallout 3 . Then find and run the file GFWLiveSetupMin and let it patch itself . Let it install the . NET framework that comes with it 3 . 5 . After installing this and patching this outside of the game you should be able to use the FalloutLauncher and current patches and windows Live . Tested with Direct2Drive version . ) On the PC version , the patch is known to greatly decrease a characters accuracy in V . A . T . S . In addition stability problems have been reported with more frequent crashes . It may also cause alt + tabbing in and out of the game to cease to work .
