Hi all! I've been reading forums for the past few days trying to find a solution to a problem that I've been having after downloading Fallout 3: GOTY edition from Steam. The problem I am having is that I am getting a soft-lock. What I mean is that the game will keep running (i.e. audio will run, npc's will move about, and enemies will attack me) but render me unable to give a command. This problem most frequently occurs in the room just before you can save Amata (the one with the dead mechanic and multiple radroaches). I've played this scenario at least 30+ times trying to figure out what seems to cause this problem and there are a variety of situations that seem to trigger this event. 1) V.A.T.S. - After using V.A.T.S. (for the 3rd-5th time) it is fairly common to input a direction (press "w" to walk forward) and then lose control. My character will only walk forward, or the direction I so choose to go, and I can't bring up any menus, either the Pipboy3000 or the "Esc" menu. 2) Walking through doorways - In my most recent play I tried to avoid using V.A.T.S. and made it to the doorway of the room where Jonas is dead. Upon entering, the game softlocked and my character just kept walking forward into a wall. 3) The "Esc" menu - The escape menu seems to have a percent chance of freezing the game, the percent chance goes up if I alt-tab out of the game. 4) Alt-Tabbing - I don't even bother doing this because it freezes the game fairly consistently, the only reason I Alt-Tab in this game anymore is to get to Task Manager to "End" Fallout 3. I have noticed that the game tends to have input lag before this problem occurs, especially in the room with the dead mechanic. Just tapping a WASD key for a fraction of a second will make my character move in the direction as if I was holding down the key for at least a second or more. I do have to open Task Manager to End Fallout to stop this process. I have read multiple forums and have tried the following solutions: A) Edit the FALLOUT.ini files (in both Programs(x86) and in MyGames) B) Turn off Realtek HD Audio Manager C) Uninstall/Reinstall Fallout 3 D) Uninstall/Reinstall Graphics Card Drivers (yes, I even removed my graphics card altogether) E) Removed Games for Windows Live F) Downloaded the Unofficial Fallout Patch G) Windowed Mode, VSync (off), AA (off), Anisotropic Filtering (off) H) Sang/Played Saxophone to my computer I) Changed properties in the Visual Effects tab SYSTEM SPECS: Intel i5-2500K @ 3.30GHz GeForce GTX 550-Ti 8GB RAM Windows 7 - 64 bit MSI P67-GD65 (Mobo) Any help would be greatly appreciated, and if you need any information I will do my best to get back to you.
