📋 About This Mod
IS THIS FOR ME? This simple utility will be of great help to you if you:
- []Alt-Tab a lot; []Have performance issues/experience mini-stutters; []Use FOSE, LARGEADDRESSAWARE, Steam or any other functionality which involves linking to/tampering with game\'s executable files.
- []Fallout 3 []Skyrim
- []Open the launcher by going to game installation folder and running the launcher (for example: FalloutLauncher.exe). []Select Options. []Make sure Windowed mode is checked. []Select desired resolution. Selecting current display resolution (see it in Windows settings) is much recommended. Any other resolution will result in distorted in-game image. This is something that cannot be solved without matching game resolution to display resolution. [] Click OK and close the launcher.
- []Download the file here at Nexus. []Extract the archive. []Place a single executable file in a folder of your choice. I suggest placing it in the game installation folder, but this is in no way a requirement. []Do not remove the file from its location as the shortcut/task you create in the next step will get broken if you do so!
- Create a shortcut or task to run application on Windows startup. This will depend on your operating system (see below) because utility has to have administrative rights to please UAC.
