– Wet asphalt water film depth now influences aerodynamics.
NOTE: you might need to raise your ride height up to 4-5mm to regain the same splitter and diffuser balance and performance on a wet track.
– General UI setup and MFD tyre pressure logic refactoring. No more automagic for ambient pressures.
Whatever the ambient temperature, the slicks are now preheated at 70°C and you can input the pressure you want for that preheated temperature.
Preset setups are already adjusted. Old saved setups will start with very low pressures and you generally need to add 4 to 5 psi extra.
Simply put a tyre pressure you desire, usually 2psi less than the hot pressure you want, and go.
– Minimum tyre pressures now at 20.3psi, as per Pirelli document request. Pay attention as the pressure can get lower than that when the tyres get cold without blankets while waiting at the grid start and can easily deflate on kerbs.

– Fixed a bug where lifting on straights would generate Trust.
– SA and RC will change at a slower rate for low AI strength (< 90%), while the balance between Trust and OBWP is untouched.
– Fixed FP2 and Q2 not displayed in server list.

Assetto Corsa Competizione – Early Access Update 7 is surprisingly out!


– Opened SRO E-Sports Series – Round 1 special event.
NOTE: This special event is controlled remotely and may be invisible for a short time after the release.
– Reintroducing Endurance game modes.
– Added Custom Race Weekend mode that allows you to completely customize a race weekend, including number of races, mandatory pit stops and time multiplier.
NOTE: Some features, such as the Superpole session will become available in the full release of the game.
– Introducing penalties for various on-track transgressions: pitlane speeding, cutting, failure to serve mandatory pitstop within the pit window.
Penalties include warnings, drive-through, stop&go and disqualification. Cutting is penalized depending on time gained. Cuts with large gains result in DQ straight away. Speeding in the pitlane may remove your fastest lap in non-race sessions, and serious speeding results in DQ straight away. Added penalty for reversing.
– Introducing pit stops with refuel, tyre change, damage repair and serving penalties.
– Introducing dynamic weather, custom weather and track status presets: the Weather page in the menu now allows you to select existing presets and enable dynamic weather for each single one of them. The preset defines the starting conditions, and also have a significant effect on what you can expect. Weather variability can range from 1 to 100%.
The Custom weather preset allows you to set each aspect of the conditions, including cloud cover, the intensity of rain and levels of track wetness and standing water.
NOTE: Selecting the Clear weather preset and high variability doesn’t mean that you can expect drastic changes over a short period. Cloudy weather on the other hand, has a much bigger probability of producing precipitation, but variability can also render conditions to improve significantly.
NOTE: The weather is designed to be dynamic over realistic periods of time. However, as it uses game-time, the player can accelerate weather transitions by using the time multiplier.
– Various improvements in cut detection and corresponding penalties.
– Fixed engine start assist sometimes failing to restart the car.
– Added input to change secondary (Racelogic device) pages. Cycles between current laptime, delta, stint time and speed). Default key is ALT+D.
– Added input to toggle wiper on and off. Uses last selected wiper speed. Default key is ALT+W.
– Replay pause: now updated on random access.
– Replay pause: now possible to use the free camera controls with the same speed as 1x speed.

– Fixed fireworks/tracklight/endmode for replay.
– Permanent spotter message groups.
– Added short wait time at the start of the formation to allow enough time for manual starting procedure.

– Fixed Safety Rating (SA) decaying in both race and solo conditions.
– Improved Racecraft Rating (RC) development directly after unlocking.
– Improved Consistency Rating (CN), should now be more sensitive to inconsistencies.
– Improved Consistency Rating (CC) to be less volatile.

– Due to the significant changes in RC and SA, both ratings will be reset. Progress in TR, CN and CC will remain.

– Fixed a bug in VR that caused the racing HUD to flicker and hit performance by constantly re-rendering the overlay.
– Introducing visual and mechanical damage:
Mechanical damage affects bodywork, suspension, aero and tyres.
Visual damage affects bodywork, windows, can deform body parts and also affects the functionality of headlights.
– Added dynamic windshield dirt effects that are cleaned off during pit stops.
– Added blurred brake disc visuals.
– Fix for Dash and DashPro cameras having wrong offset/rotation when using custom settings.
– Fix for wrong camera pitch after F1 cycle with lock to horizon enabled.

– First release of the new multi-page and multi-functional widget, replacing the old Standings widget.
It contains a real-time track position page, standings, pit stop strategy and car electronics. Navigation is possible with all navigation inputs, including keyboard arrows, D-Pad and mouse.
It enables the player to control all car-related inputs (TC, ABS, wiper, lights, rain light etc.) on the fly, without having to map each key to the steering wheel/button box.
NOTE: the MFD uses navigation inputs, which means input overlap may need some bindings to be remapped.
NOTE: the MFD navigation in VR is not yet functional, thank you for your patience.
– Introducing weather forecast and grip status widget: a simple widget on the HUD that alerts the player of changing weather forecast in 10 and 30-minute projections. It is also visible on the race and setup screens.
NOTE: It shows weather forecast in real-world time, which means in accelerated sessions the forecast will be translated to a time that is easier to understand for the player.
– Fixed timing issues on car dash displays.
– Additional server information on Multiplayer lobby page, including session status and dynamic weather indicator.
– HUD pages can now by cycled backwards using Shift+F2.
– Added realtime track position widget.
NOTE: it is now the default page inside the MFD in multi-car sessions.
– Weather and Track status summary now visible on the weather tile in the Single Player page.
– Added helper information for various single player pages and the new weather page.
– Added tyre pressure readout on tyre app to help users who do not use cockpit cameras monitor tyre pressure.

– Optimizations in multithreaded CPU calculations.
– Brake duct simulation. Influences brake disc heat and braking efficiency, but also rim and air temperature inside the tyre and thus pressure and general tyre temperature.
– Brake duct settings in setup aero screen for all cars. Setting 0 is a completely closed duct and can provoke brake fade very very fast, exceeding 1000°C. Never to be used in a real race, but added for simracer’s gratification. Setting 6 is completely open and can keep the brakes very cold.
The peak temperature is of course important but keep in mind that a low setting not only heats up more, but doesn’t cool down the brake in the straights, so the heat accumulates and keeps dissipating heat to the tyres.
Ideally you want your front brake HUD to show green or slight yellow at the end of your braking zone and your rear, green. Don’t judge after just 2,3 braking zones. Do a couple of laps and let the brakes do some heat/cool cycles to arrive at a balanced condition.
– Suspension damage for all cars (WIP).
– Basic aero damage for all cars (WIP).
– Optimizations to tyre flex at very low speeds, to diminish or even eliminate an FFB vibration around 50kmh.
– Added tyre pressure and potential puncture influenced by riding kerbs aggressively.
If you ride stepped kerbs with low tyre pressure (cold tyre) the tyre flex might provoke pressure loss. How much pressure loss is not easy to predict, but the lower the pressure the more pressure loss will happen. Hitting the kerbs and sliding laterally over them with low pressures can result to a tyre deflation losing all pressure instantly in less than a lap. Avoid kerbs with very cold tyres at all costs. When the tyre has adequate pressure, the risk of loss of pressure is almost null so you can attack kerbs again. Be careful when racing on slick tyres when it starts raining. The tyres will lose temperature very fast and so you must avoid kerbs until you enter for your pitstop. Any pressure over 26psi is relatively safe. The whole system is complex, brand new and we are still working on it. Thank you for your patience.
– Improved collision model, which significantly benefits car-to-ground collisions. Also brings significant improvements to car behaviour when attacking any kind of kerbs.
– Start ECU assist now has more discreet intervention because of the launch control implementation. To start, just floor it in 1st gear with clutch on and revs will be limited to 5000rpm. The less start assist should aid when trying to spin around on grass after a track exit.
– Tweaked TC logic for all cars. Permits more slippage in straight line and more angle. Can result in more oversteery cars in lower TC settings so take care when track is slippery.
– Fixed bug that could cause an event to start with tyres in ambient temperature if user clicked directly on drive.
– Wet tyre adjustments.
– Slick tyres optimum pressure range now 1-2 psi higher.

– Exterior engine volumes are now higher.
– Interior engine volumes are now higher.

Assetto Corsa Competizione Early Access Update 0.5 is out on Steam!


– New Emil Frey Jaguar G3 car.
– New laserscanned Circuit Zolder racetrack.
– New special events with online leaderboards.
– Fixed disappearing main menu UI in VR.
– Texture memory optimizations.
– Fixed a chase cam rotation bug.
– Fixed a TV camera bug.
– Car light improvements in TV camera views.
– New inertia calculation method and new more accurate inertia value (advice for setups, use softer fast damper to let the body move and settle, instead of having the car and wheels jumping)
– New motion ratio calculation for dampers resulting in more accurate values dedicated for each car.
– New ABS feature. ABS now never lets higher than 70% difference between left and right brake pressure. Improves behaviour on extreme torque vectoring, like braking and going through a water puddle with one side of the car, but can result in inner wheel locking if driver insists braking hard while turning into a turn. Might need more rear brake bias on certain cars.
– Improved ABS logic, resulting in better turn-in under braking, on certain cars (most notably modern cars such as the Huracán, F488, BMW M6).
– Improved TC off on gear-change functionality. TC is instantly switched off and on again when a gearchange occurs, in order to protect the engine and drivetrain from heavy vibrations, especially on situations where kerbs and the engine limiter are involved (part of real cars’ TC logic too, occasionally they will even not allow the gearchange). Now the TC off timing is car-dedicated and optimised. Some cars might handle a gear change better than others.
– Improved tyre thermal model, especially wet tyres.
– Improved tyre grip when tyres are overheated, such as after a spin.
– More tyre wear when tyres are overheated, no free meal.
– Corrected bumpstop position and functionality of the Ferrari 488 GT3.
– New ECU maps for all cars. ECU maps now influence power, fuel consumption and throttle maps. Usually the lower number is the more powerful and has the most power consumption. After the initial 3-4 values, it switches to wet ECUmaps with similar power and fuel consumption but different throttle maps. Please check the official forum for all the released cars’ ECU map characteristics.
– New launch control for all cars. Now with manual clutch, just engage 1st gear, put the clutch and accelerator to the floor and the engine will stabilize around 5000rpm. Release the clutch gradually while keeping the accelerator fully open to avoid stalling.
– Audio engine optimizations
– Fixed potential wrong volumes switching cameras
– Fixed time multiplier for the end race replay
– Fixed wrong trackmap cars position during replay
– Intro sequence updated
