Posted by on 17 May 2016 02:11 PM

The below change log represents the key changes made to FSX: Gold Edition to create FSX: Steam Edition.


  • Microsoft Flight Simulator X: Steam Edition is now built using the VS2013 compiler for better optimisation and performance. (Still makes use of VS2005 libraries for backwards compatibility.)
  • Updated splash, launcher and mission preview images for FSX:SE versions.

Multiplayer, networking and communications

  • Gamespy networking now replaced by new Steam networking.
  • Game chat now integrated with Steam chat
  • Friends/Banned lists now integrated with Steam.
  • Game invites now use Steam.
  • Host networking defaults to a single port 6112.
  • Host networking uses 27016 for Steam Master Server Browser.
  • Host timeout (loss of connection to host) now 35 seconds by default (was 55).
  • "Disconnected" message dialog now retained on screen for 4 mins before automatic dismissal (was 30 secs).

Steam Support

  • Top Down Camera (camera view select 4) was previously bound to F12 by default which is normally used for Steam's screenshot feature. Camera View Select 4 now uses Shift+F12 by default to avoid potential clash.

Compatibility with FSX boxed

  • FSX and Microsoft Flight Simulator X: Steam Edition co-Existence feature allows both versions to be installed on the same machine.
