Fallout 3 Crashes when trying to exit Vault 101

fallout-3pctechnical-issues

So I decided to start playing Fallout 3, in the build up to Fallout 76 releasing sometime later this year(hopefully). along with the other Fallout Games. I loaded Fallout 3 and played through the first quest, Escape!, and as I open the Vault door towards the end of the quest, the game becomes unresponsive, and I cannot move my character. Interestingly enough, the sound files continue to play as if the game is still running.

I have all the DLC Packs for Fallout 3, and have them enabled from the get go in the main launcher, so I tried disabling them and tried launching the game from it's core .esm file, no dice. I have NO mods in this game whatsoever, so mods cannot be the issue.

I am out of ideas to try and get the game to start working again, any ideas? Maybe something to do with the game's console?

Thanks for viewing!

My best guess would be to try and alter some settings in the game.
Go to the installationfolder of your game and locate the file FalloutPrefs.ini this file might be located in the submap Fallout3. Open this file with a texteditor such as notepad and find the following line and change its value bDoHighDynamicRange=0 to bDoHighDynamicRange=1

Try to start the game and exit the vault. If this doesn't work, you could try some other settings.
For this you'll need to find the file Fallout_default.ini also located in the gamefolder.
Find the following values and change them:
Change bUseThreadedAI=0 to bUseThreadedAI=1
Change iNumHWThreads=2 to iNumHWThreads=1

If either of these options don't exist, you should add them in the [General] block of settings.

What this will do:
bDoHighDynamicRange turns on HDR.
bUseThreadedAI determines if actors' behavior scripts can be split into multiple threads. This might improve performance*
iNumHWThreads controls the number of threads the game uses in general. *
