About This File

This application was first released on the 6th of November, 2011. It allows you to play Battlefield 3 in a borderless "fullscreen" window, allowing you to easily and conveniently Alt+Tab to other applications.

Realmware BF3 Borderless is a simple program which gives you control over the window that Battlefield 3 runs in. The main purpose of this is to run Battlefield 3 in a fullscreen window. This has the advantages of both worlds: you get full use of your screen, and the convenience of easily switching to other programs. You may be familiar with this from games such as Left 4 Dead, which natively supports running in a fullscreen window. This page lists each and every feature of the program.

Easy to use

  • You will be automatically notified about any new updates for BF3 Borderless.
  • If you wish, you can leave BF3 Borderless running in the Windows system tray. It will then apply your window settings to Battlefield 3 whenever you run the game.


  • Resize the game window to any exact size that you want.
  • Automatically centre the game on your screen, if you want.
  • Apply your settings either automatically or manually.
  • Minimise BF3 Borderless to either the taskbar or the system tray.

Improve performance
