Only try this as well if the instructions above do no fix the issue.HOPE THIS HELPS!!!-Genji Last edited by Wasabi; 15 Mar, 2019 @ 12:32pm The author of this topic has marked a post as the answer to their question. Click here to jump to that post. Originally posted by Alonts: Guys, I just fixed the problem completely different way, because for me the problem was not in the wrong settings of .ini file but in the system's "documents" folder which wasn't at default location due to superb help of Microsoft's OneDrive software. The path to it will be going through the OneDrive (if it was ever installed at your machine, which I bet it was) which mess the things around. Basically, the game couldn't use the settings of game's config because it couldn't see it. To fix that you would need to play around the registry structure and change a few keys manually but I already found everything 4 you, so long story short, just follow the simple instructions and enjoy the full screen after :)This instruction comes from the Microsoft support site so don't worry, it's completely safe to use.We need to create a .txt file (anywhere, you can use your desktop) open it and put in the following below:@echo offtaskkill /f /im explorer.exetimeout /t 2 /nobreak >nulif not exist "%UserProfile%\Documents" mkdir "%UserProfile%\Documents"reg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders" /v "Personal" /t REG_SZ /d "C:\Users\%USERNAME%\Documents" /freg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v "{f42ee2d3-909f-4907-8871-4c22fc0bf756}" /t REG_EXPAND_SZ /d %%USERPROFILE%%"\Documents" /freg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v "Personal" /t REG_EXPAND_SZ /d %%USERPROFILE%%"\Documents" /fattrib +r -s -h "%USERPROFILE%\Documents" /S /Dtimeout /t 1 /nobreak >nulstart explorer.exe To make it work, after you save the .txt file you have to change it's extension to .bat to make it runnable as a script. After that just run it, it will complete all the tasks and close itself. That's it, the game will run Full Screen now if you set it that way in Launcher options. P.S.for those who have no idea how to make a file extensions visible, go to "search" at your system, look for the "File Explorer Options", go to "View" page and tick off "Hide extensions for known file types" I've spent half a day to find this fix, but finally it worth it. Enjoy ;) < > Showing 1-15 of 57 comments roadkill03 View Profile View Posts 19 Mar, 2020 @ 11:53am 1 1 2 I tried all of the above but no luck. Because of another game I turned off OneDrive backup of the documents folder and then it finally worked! #1 Out Of Bubblegum View Profile View Posts 19 Mar, 2020 @ 11:59am Why would you need borderless and fullscreen both set to one? Borderless is only for windowed mode. It should be overwritten/ignored when using fullscreen, I assume. So it may not matter what it is set to. I would still set it to zero. Unless there is a bug where it must also be set to one. The trick seems to be, to play the game in windowed, borderless and get it working that way with the correct resolution. Then change to fullscreen. Then never use the games video menu again. Last edited by Out Of Bubblegum; 19 Mar, 2020 @ 12:11pm #2 Wasabi View Profile View Posts 21 Mar, 2020 @ 9:35am

There was a bug when i made this last year #3 mgnjob88 View Profile View Posts 10 Dec, 2020 @ 4:01pm Not working :( #4 Cliff View Profile View Posts 1 Mar, 2021 @ 12:30pm IT WORKS!!!!! Thank you really much. Now it's worth playing again.I just want to ad that you need to save the changes manually via file-->save. If you save via "close window- button" it WON'T save the chages you just made. #5 Cliff View Profile View Posts 1 Mar, 2021 @ 12:31pm

Look at my comment #6 Bandy View Profile View Posts (Banned) 1 Mar, 2021 @ 3:14pm instead of a thread that will be buried and disappear, why not consider posting a brief guide in that section of the game here? Second choice from the right, top of this page...Maybe there is one for this there already?

I feel sorry for anyone that has to jump thru hoops. #8 Ferus View Profile View Posts 2 Mar, 2021 @ 12:03am Tried all that and still crashes before getting to the vault elevator. #9 Iron Knights View Profile View Posts (Banned) 2 Mar, 2021 @ 12:52am Do you have an nVidia GPU and did you turn off Weapon Debris ? #10 Bandy View Profile View Posts (Banned) 2 Mar, 2021 @ 6:31am

Ah yes, the weapon debris bug, forgot about that, he's likely correct! #11 Da_Noi_Phai_lam View Profile View Posts 16 May, 2021 @ 12:34am Thanks you so much, I fixed it. Right-click on Document -> Turn off cloud save and do as Sidenote #12 Sevatar View Profile View Posts 3 Aug, 2021 @ 8:42pm
