Fallout 4 won't open - Windows 11

[MaxPresi]

Fallout 4 does not open. I've tried everything, with and without mod, removing everything and downloading again (removing appdata folder, documents and Steam common)

Am I missing some 3rd program?
It doesn't even crash from the black screen, I click to open it and it gets stuck in taskmgr without doing anything and it never opens.

Maybe it just doesn't work on Win 11? Tried like a compatibility mode thing?

Did you fresh install Win 11 or upgrade?
Have you installed / re-installed your motherboard and GPU drivers?

Runs fine for me on Win 11.

Brand new gaming rig arriving in 3 days with Win 11 factory installed w/Nvidia 3700 series GPU, and i7 12-core CPU. Be interesting to find out if my Beth-games will work with it.

your video card will not be recognized. Guaranteed.

Windows 11 is not ready for gaming and I'd strongly recommend not installing it until you can confirm that whatever kb updates it gets aren't already broken.

I've been playing with W11 for almost three years now, I honestly don't understand your very personal adversities, but which you shouldn't pass on to users.

Check if the GPU is recognized by the O.S. then update the drivers, but if it work with other games..
Delete the contents of the Fallout 4 folder in Documents (not the saves).
After all those steps it takes a restoring game files through Steam, then try to run the game without additional mods, by disabling (not uninstalling) them via ModManager.

The same problems. I used to have problems launching the game through a 300hz monitor, but it was fixed by changing the values ​​in notepad, then with the update to Windows 11, even this does not help, and even if I change the monitor settings to 60hz, the game will only be in a small window. Complete ♥♥♥♥♥♥♥♥.

iPresetInterval=1
bBorderless=0
bFull Screen=1
iSize H=1440
iSize W=2560
Edit this in Fallout4.ini in game folder and in Documents folder. Set your resolution value, which are mine.
Use the search function in the notepad or your .text file.

I did as you advised, but this crap still only opens a black screen with sound. I already believed that your method would help, but this curse, judging by everything, does not fix in any way...

I wrote a longer post that I deleted because I thought you were saying it does not run at all. Now I understand that the app does run but it's just all black.
It's definitely your settings or drivers or both. I'm running it fine on a new Windows 11 install

[Corsic]

No, the problem is not in the drivers or settings, because before Windows 11 I had a similar problem, but because of the 300hz of my monitor, but there the problem was solved by changing the value of iPresentInterval= to 0. But now it does not help at all and the black screen with sound is stable. Other games from Bethesda have the same problem, that is, the problem is most likely between Windows 11 and the 300 Hz monitor and the game engine.

Which would make it a driver problem or a setting problem.

the first time i started fallout 4 on my new system (came with windows 11, fast M.2 ssd, rtx 3080) it took a long time to actually start, it actually started as i was about to end task it...
once i finally got in game it loaded very very slowly with just a black screen, but ran fine once it did load, then loading areas was very very slow again.... BUT it all works great now.

took a bit of research and finding similar topics around, (it's not windows 11, happens on win 10 as well) people suggested a "load accelerator" mod, so, i tried it and what a difference, game works better then ever now.

if you want achievements, don't forget the "achievements mod" as well.

If nVidia GPU turn off weapon debris in launcher options. I would need your full PC specs..
Stop modifying game files, you're not a programmer and don't know the source code for this game. You don't know what the executables expect from the .ini and how they are used.
1) Set your monitor to 120-144hz.
2) Disable V-Sync in Game and in Drivers.
3) Enable Enhanced Sync (AMD)/Fast Sync (nVidia).
4) If your monitor supports Freesync/G-Sync, enable that too.
5) Turn off VSR in Drivers (small/big square problem).
6) Run Game in Full Screen.

More than one year later, this problem is still happening. I bought a new laptop, i9, nvidia 4080 and it;s not launching. It works fine in the old laptop.
I have already tried renaming it, updating nVidia, verifying integrity of the files and now downloading it again.
Is there something else at this time that I can do?

win 11 comes with default security settings. neither steam nor the game installer nor the game make any changes nor bypass whatever antivirus, security settings, folder permissions, running programs you have on your system. up to YOU to manage all that for this game and any other game/app you install.

game launcher needs to create folder
Documents\My Games\Fallout4

folder should contain files Fallout4.ini Fallout4Prefs.ini
after game launcher runs and you set your graphics settings
and after game starts your saves folder.

if these files are missing

check antivirus log? might be blocking game/game launcher.

check windows security/controlled folder access.
if on add exceptions for game launcher/game.

check windows event viewer and also windows reliability history.
might be a game crash event or system related problems.

running Windows One Drive? One Drive moves the ini/preference files to the one drive.
turn OFF one drive. uninstall it if not needed.

or if you need one drive, should be exclusion/exception option.
exclude the games Documents folder or tell one drive to leave a local copy of the files
details in the one drive user manual

laptop? make sure game is using dedicated graphics card
and not motherboard graphics

you have an nvidia graphics card, run geforce experience, optimize the game thru that, then launch the game. sometimes the nvidia settings work better than what the game thinks should work.
