Patchnotes via Steam Community

The wait is finally over! After many months in Early Access, Assetto Corsa Competizione, the Official Blancpain GT Series game, launches today on Steam:

Featuring 51 teams, 280 selectable drivers and 14 manufacturers, Assetto Corsa Competizione allows sim racers to experience the real atmosphere of the FIA GT3 homologated championship.

Developed using Unreal Engine 4 to ensure a visual treat, Assetto Corsa Competizione sets a new standard in driving realism and immersion, including the introduction of variable weather conditions and night races to influence challenge and racing strategies.

Virtual drivers will experience a simulation of the Blancpain GT Series by taking the wheel of one of the game’s featured luxury motorcars including Ferrari, Lamborghini and Aston Martin, or choose from a number of other prestigious GT racing cars, all replicated with an outstanding level of detail.

“Never take anything for granted, even if you have the Assetto Corsa experience behind you! Assetto Corsa Competizione has been completely rebuilt from scratch, not only to best harness and adapt to the Unreal Engine 4 capabilities, but also to define a new standard in terms of realism and car handling. The opportunity of working with SRO GT Series has allowed us to furtherly extend our know-how and our specialization in responding to players’ needs, as well as those of real drivers. Reaching the finish line was not easy, but it certainly was exciting and satisfying, also thanks to the support of our incredible community, which once again understood and grasped the spirit and value of the Early Access program at its best. But our challenge is yet to be finished: even after the release of version 1.0, we will continue to work on expanding and improving Assetto Corsa Competizione to the best of our abilities” – Marco Massarutto, Co-founder and Brand & Product Manager of Kunos Simulazioni.

  • Added Brands Hatch Circuit.
  • Added all drivers, teams and unique car liveries from the 2018 European Blancpain GT Series.
  • Switched to UE 4.22.
  • CPU optimizations that should bring significant improvement on all tracks.


  • New ABS logic update for all cars. ABS level can greatly influence your braking distances depending on weather and track conditions.
  • Physics-based flatspotting re-enabled and greatly improved. You can badly flatspot your tyres with 2 or 3 high speed spins. The tyres will tend to lock up on the same flatspot, high vibrations to the suspension (and Force Feedback) when the flatspotted tyre is put under load (braking, cornering).
  • Fuel load simulation/testing. You can find this new slider under Aero/Rear box. This only works in practice sessions. It is disabled in qualification, hotlaps/hotstint and race sessions.
    Once you have created your setup, you can move this slider and load the car with the fuel you want (less or more), and the ride height will change accordingly. The resulting ride height might be higher or lower than the actual setup. When you modify the ride height, the option will be disabled again.
  • ECU and throttle map improvements for all cars
  • Tyre sets implemented. There is a limited number of slick tyre sets available for race weekends (which can also be set to unlimited.)
    When enabled, make sure you keep an eye on tyre sets and their wear in the Setup/Strategy page.
    ACC assigns the following number of tyre sets for each different race type:
    Sprint race weekend: 5 sets
    Endurance 3 hours race weekend: 6 sets
    Endurance 6 hours race weekend: 9 sets
    Endurance 24 hours race weekend: no limit.
    There is also no limit for wet tyre sets.
    The feature only works in offline gameplay for now. Online game modes feature unlimited tyre sets.
    Individual sets still get wear, so make sure a new tyre set is selected in every session (there is an automatic progression even if the player doesn't change the set manually).
  • Kerb grip updates. Kerbs are now VERY slippery when wet.
  • Rubbered wet line update. Rubbered wet line can be VERY slippery until cleaned by heavy rain.
  • Improved tyre model bumps and kerbs impact.
  • Improved rolling resistance influence.
  • Improved wet grip simulation and wet rolling resistance influence.
  • Improved tyre wear. Fresh tyres give maximum performance for 3-4 laps depending on track, then lose performance fast and stabilize after 6-7 laps. Afterwards they will lose performance gradually but laptimes might remain stable or very little loss, because of losing fuel weight.
  • Added wind simulation in variable conditions. Wind will be higher just before and during a weather change (from sunny to wet and vica versa). It will settle to lower values when the weather is stable. Wind values have been taken from the real circuits on the actual race date and are used as a probability base for the in-game wind simulation.
  • Updates on all car Balance of Performance for all circuits.
  • Fixed an issue that resulted in FFB values passed during the fadeout after pressing Quit in the pause menu - probably also resulted in gamepad vibration remaining in the UI after quitting.


  • Optimized channels usage.
  • Improved opponents positional audio and distance scale.
  • Overall volume balance.
  • Reworked audio listening-priority.
  • Reworked tyre damage / crew chief warning logic.

  • Added Projection Correction option to the View Settings
  • Removed vignette effect from TV Cameras.
  • Adjusted sky.
  • Adjusted rain particles.
  • Fix to aux lights not being linked to moving car parts.
  • There is a new type of fake body and tyre shadows on all cars that produce less clipping.
  • Opponent visibility now doesn't affect TV cameras.
  • Helicam added.

    Includes two seasons, including introductory test sessions and an introduction to Sprint and Endurance racing in a car of your choice.
  • Added Save Game functon - initial implementation allows one game session to be saved and loaded. Save feature is limited to Single Player race weekend modes. Multiple save option and save during career/championship sessions to be added later.
    Championship and Career progress is saved in between events.

  • Fixed possible broadcast replay crash due to wrong timing.
  • Improved AI formation logic to follow the player car if it is the polesitter.
  • AI to follow the player car during formation if he starts moving before the 10-second waiting time. This way the player is no longer able to create a gap by starting early from pole.
  • Quick Race and Custom Race Weekend car selection and opponent logic completely revised: should be way more user friendly now, and more importantly, there are no entry duplicates in these modes anymore.
    Essentially the player now can select every single entry and there is only one version of each, same for the opponents, also ingame the player gets the appropriate body kit, so the field will be mixed.
  • Added autosave for highlights
  • Gameplay and AI logic additions:
    The AI will now go back to change tyres if the weather changes (with a randomized required-rain level in order to not have them all going to the pit together), and when fuel is low.
    The same system pops up a message to the player about tyre choice.
  • Driver stint logic is added.
  • Sprint race no longer has the driver swap option because it's mandatory, it is a forced swap if the player pits in the pit window for the first time.
    Endurance race instead always has the swap option open.
  • Track status on the top of the screen is now connected to the race director.
  • AI is now faster when re-entering the pits.
  • Fixed a bug that allowed the Pit Window time to be the same as the Race Length in short custom race weekends.
  • Fireworks only start when leader crosses the finish line.
  • Added fixed-time refuelling rule for Endurance weekend (non-endurance races will have refuel time depending on fuel amount, in endurance mode -> fixed time).
  • Podium sequence added after race sessions if player finishes in top 3.
  • AI now slows down in the cooldown lap.
  • Single player green light now starts earlier and not so close on the S/F line.
  • Single player double formation tweaks on some tracks (closer to the last curves).
  • Penalty system:
  1. There is a huge difference between cut estimates of
    a) first lap without having had the corner in a clean way yet
    b) lap after having a clean reference for this corner
  2. Zolder + Paul Ricard now should invalidate the next lap in Hotlap, Superpole, Qualifying if the last corner was cut in order to make the next lap faster.
  3. Pit entry/exits won't trigger false positive penalties.
  • AI levels tweaked in wet conditions: there is a lot more random factor in their driving. They also "see" puddles now.
  • End-of-race sequence reworked: now possible to either drive a full cooldown lap (with the AI) or press ESC after crossing the finish line.
    Pressing ESC before the opponents would finish the race lands the player in a screen that shows live leaderboard and unfinished opponents. Once all opponents finish the session, the player is taken to the official summary results page.
  • Added improved automatic retire function for cars stopped on the track, both AI and player. Time tolerance depends on position and whether or not the car is facing the wrong way.
  • Reworked pitlane spline logic for AI pit entry
