Fix crash when starting new game [GOTY-2024]

[mukunku]

After successfully launching the game when you click the New Game button you might experience a crash if you're using an AMD or Intel graphics device. To fix it you need to add a missing DirectX 9 dll file to the Fallout 3 installation directory.

You can download the missing dll file from here (you will need a Nexus Mods account): Intel HD graphics Bypass package[www.nexusmods.com]

You don't need the .ini file, just the d3d9.dll file. Copy and paste that to where Fallout3.exe is which is something like: ../steamapps/common/Fallout 3 goty/Fallout3.exe.

There isn't an existing file to replace, so you add this as a new file. And even though it says "Intel Fix" it works for AMD as well.

THIS INTEL THING DOES NOT DO ANYTHING. IT doesnt fully utilize your gpu and only uses about 18-20% of it. You will register 100+fps and it looks like its running 30fps because its pretty much Snake Oil. People keep regurgitating this and its not a TRUE fix.

There's still more that needs to be done, it's a pretty bad PC port and everything was designed to run at the 30fps cap on console.

If you don't want to install a ton of mods to fix it the best way I could find was to edit these 2 lines in your Documents\My Games\Fallout3\Fallout.ini

iFPSClamp=120
This speeds up the physics engine to match your fps which also increases your fps when it's not set to 0. However it also effects the game speed depending on your framerate, you should set this to be just under your average fps, not your fps cap. I have 165hz monitor and found 120 worked best for me.

fMaxTime=0.0083
This fixes the game running too fast when you have too high of an fps, again this should match your average fps not your fps cap. Use the table below to find the right value that works for you.

fMaxTime=0.0333 for 30fps
fMaxTime=0.0166 for 60fps
fMaxTime=0.0133 for 75fps
fMaxTime=0.0111 for 90fps
fMaxTime=0.0083 for 120fps
fMaxTime=0.0069 for 144fps
fMaxTime=0.0042 for 240fps

Changing these values made my game run at 155+ fps but it slows down to 120fps in combat which is why I went for the 120fps values.

The combat bug has to do with the health bar animations which can only be fixed with the FOSE or capping your fps to 60 in your graphics card control panel. I decided to just dial in my physics settings to stay above 120fps.

Works for me. Thanks.

Used only d3d9.dll file and put it into folder where .exe file is. It makes your game to think you have nvidia GPU.

Thanks, it didn't work with the folder the main post gave, but that did it.

AMD released a driver update a little while ago that fixes this issue.
