1.5.8 Hotfix


  • Separated Dedicated Server as a standalone item in the Steam/Tools library.
    NOTE: The Dedicated Server and the Broadcast SDK will no longer be part of the main game content but they will be found under the „Assetto Corsa Competizione Dedicated Server“ as an item in the Steam Tools library.


  • Adjusted weather scaling with variable weather – weather patterns normalized to reduce the likelihood of unpredictable and extreme weather when using high weather variability.
    NOTE: the user can now be more generous with cloud level and variability settings, the level of variation will retain its effect on the rate of weather changes but without the byproduct of accumulating into extreme scenarios.
  • Unified and improved Singleplayer and Multiplayer weather model.
  • Optimizations to the weather model to better align Single Player and Multiplayer behaviour.
    NOTE: updates to the Server/Multiplayer side will be detailed in the Dedicated Server changelog and the Server Handbook.


  • Fixed an issue with wind scaling versus weather variation in Single Player.


  • Fixed a potential crash caused by an issue with the Logitech plugin accessing external libraries.

1.5.7 Hotfix


  • Fixed pit exit erroneously triggering blue flag when driving near the wall at the start-finish line on Laguna Seca.
  • Fixed pit entry erroneously triggering blue flag when driving near the pit entrance wall on Kyalami.
  • Fixed a potential inconsistency with track limit warnings accumulated on existing pending penalties.
  • Fixed an inconsistency when serving a drive-through penalty without having the serve penalty checkbox selected.


  • Slight adjustments to the 2019 GT3 season balance of performance.
  • Slight adjustments to the 2019 GT4 season balance of performance.


  • Decreased streaming memory pool in EPIC texture setting preset to prevent potential video memory overload on mid/high-range cards.

1.5.6 Hotfix


  • Fixed an issue with receiving a time penalty when a car was performing a pitstop would clear without getting added to the pitstop time.
  • Server: fixed an issue in the server that would prevent the result.json to be populated by lap data when the server was restarted due to all clients disconnecting.
  • Fix to the crash that occurred with the Chevrolet Camaro GT4R on driver swap.
  • Server: fixed erroneous car visibility in certain situations with limited opponent visibility.


  • Fixed an issue when a puncture caused by excessive tyre wear would compromise the suspension geometry upon returning to the garage.
    Similarly to other puncture scenarios (pressure loss and flatspotting), the punctured tyre is now „patched up“ after a pitstop/in garage but remains in a critical condition and is not to be reused.
  • Adjustments to wet tyre wear in different temperatures.


  • Corrected credits page image compression.
  • More detailed tyre condition indicator in the Pitstop MFD page for used tyre sets
    NOTE: ranges from white to black based on the worst property of the worst tyre of the set.
  • Corrected an issue that prevented dry tyre set 1 to be selected in the pitstop MFD when the car was on wet tyres.
  • Fixed UI leaderboard erroneously showing placeholder entry with no laptimes to show.


  • Corrected windscreen wiper mask for the Mercedes-AMG GT4.

1.5.5 Hotfix


  • Time penalties issued by the race admin are now served on the next pitstop as per real life.
    Opens up the possibility of „pitstop ballasts“ in organized events with mandatory pitstops.
    Time penalties that are not served will be added to the total time on session finish as before.
  • Server: fixed an issue with post-session state management in Multiplayer.
  • Serveable penalties (DT, SG) are no longer forced into a to-serve state by default when the car is in the pitlane.
    Avoids scenarios where cars can become compromised when receiving an admin penalty inside the pitlane or when already performing a pitstop.
  • Server: post-race time penalties are now applied to the final results on session complete state.
    NOTE: Final results are calculated when the last car on track crosses the finish line or when the „sessionOverTimeSeconds“ phase is up.
    NOTE: When post-race penalties are added to the car’s total time, the penalty labels on the leaderboard/standings turn from red to grey.
  • Severity of converted post-race time penalties are now track dependent to factor in longer pitlanes (e.g. at Spa).
  • Server: detection of idle players so that the race complete state (and result generation) does not wait for the session overtime to be over if there are idle cars in pitlane.
  • Revised polesitter side on all tracks (both Singleplayer and Multiplayer).

  • Realtime widget: fixed inaccurate gap values versus cars in pitlane during race sessions.

  • Realtime widget: more accurate gap calculation for cars stopped on track.
  • Removed automatic brake change check in the MFD Pitstop strategy unless the brakes are worn out.
