Low FPS in Windowed (Fullscreen) Mode

  • We're aware of an OS bug where running some games in Fullscreen (Windowed) mode an cause a severe drop in FPS in-game. We anticipate this is addressed in the next OSX build.

    In the meantime, there are two different workarounds that may help!

    1. Running the game in Fullscreen

    Running the game in fullscreen should not have the FPS degradation above. This does limit some functionality, such as ease of tabbing out of game without redrawing your desktop and Applications.

    2. Minimize all background windows using Flash (including Battle.net App)

    Flash applications drawn behind a Windowed (Fullscreen) application cause FPS loss. The Battle.net Desktop App uses Flash elements as well, so minimizing this on launch can help.

    1. Open the Battle.net App > Settings.
    2. On the General Tab, locate the When I launch a Game dropdown.
    3. Select Close the Battle.net Window
    4. Click Done to finalize your changes.
