FSImp - Download


It is advised to use the most recent version of FSImp as it is tested with older and recent versions of X-Plane.

Newer versions can be simply installed on top of existing ones.

  • existing parameters settings will be taken over by the newer versions.
  • new parameters will be defaulted
  • scenery.cfg will be scanned again automatically
  • cached tiles will be deleted and regenerated automatically

    Thank you to all of you who have purchased an FSImp user key. If your user key does not support the latest version, or you do not have a user key, then FSImp will run in demo mode and stop showing bitmaps after 20 minutes. The FSImp user key contains the final version number of FSImp that it supports.

    changes 1.05

  • Important - now uses up all the time slice to reach the target FPS. This allows FSImp to load sceneries/bitmaps and do its calculations more quickly. However it is more important in v1.05 to specify your target FPS rates using the performance dialog. The default frames per second targets may be too low for your system and are as follows
    16 FPS in the air
    12 FPS on the ground
    6 FPS when paused
    4 FPS when loading after teleport
