Bsimracing Sim Racing Resources and News for the racing enthousiast.
Kunos Simulazioni and 505 Games released the Assetto Corsa Evo Version V0.9 update. Alongside some major improvements and fixes, the update adds three new cars, online leaderboards with updated events, updated physics, handling, and an updated tyre model.
The developer stated that Update 0.9 will not mark the final release of the Early Access Program, and confirmed that Free Roam is on the way and will be part of Assetto Corsa EVO during Early Access.
Update Highlights:
- Three new cars:
- Audi R8 LMS GT2 – A high-downforce GT customer racer.
- Audi R8 V10 performance quattro – Mid-engine AWD road-going supercar.
- Mazda RX7 FD Spirit R (Type A) – Legendary Japanese rotary sports icon.
Special Events & Online Leaderboards
- Asynchronous Competitions: Fixed car, track, time-of-day, and weather scenarios where all players compete under identical track conditions.
- Hotlap & Hotstint Modes: Hotlap tracks single-lap deltas (with the ability to target rival ghosts via the MFD), while Hotstint evaluates multi-lap consistency across sustained stints.
- Limited Attempts Option: An optional parameter restricting recorded leaderboard attempts to mimic real-world qualifying pressure.
Multiplayer Mandatory Pitstops & Strategy
- Pitstop Windows: Server hosts can enforce mandatory pitstops for endurance and longer sprint races.
- In-Car Strategy Management: Drivers dynamically adjust tyre compounds, tyre pressures, and fuel loads on the fly via the Multi-Function Display (MFD).
- Exploit Prevention: Teleporting or returning to the pits inside the pitlane now carries proper time penalties to prevent skipping standard service stops.
Physics & Tyre Model Overhaul
- GT Slick Tyre Model: Reworked racing slick dynamics across GT and Cup cars (from the MX-5 Cup to GT2/GT3/GT4 and the F40 LM), refining slip-angle limits, contact-patch load distribution, and realistic camber trade-offs between braking and cornering.
- Drivetrain & Differentials: Upgraded limited-slip differential (LSD) simulation, including setup options for LSD friction faces and fixes for AWD clutch lock controllers.
- Throttle Response Calibration: Enhanced progressive throttle curves on new additions, rolling out progressively to legacy vehicles.
Controls, FFB & Visuals
- Instant FFB Recovery: Sub-second automatic Force Feedback reinitialization after Alt-Tabbing, device disconnects, or wheel base power-cycling across DirectInput, Fanatec, Logitech, and Thrustmaster hardware.
- FFB Linearization: Added native support for custom lookup tables located in the saved game directory to linearize wheel response curves.
- Exposure Fusion & Graphics: Implemented dynamic exposure fusion mimicking human vision adaptation, real-time post-processing adjustments in the View Settings menu, visual wind rendering, and temporal dithering improvements for DLSS/FSR.
Changelog:
CONTENT
- Audi R8 LMS GT2
- Audi R8 V10 performance quattro
- Mazda RX7 FD Spirit R (Type A)
MULTIPLAYER
- Fixed a crash on server disconnection
- Fixed admin commands sent twice to the server
- fix for player receiving a duplicated race number when rejoining a server with a custom number
GAMEPLAY
- fixed suspension repair also repairing car body damage
- global CPU-side optimization work
- fix for raindrops left on windshield after exiting a rainy session
- fix for dash display on HUD disappearing in certain scenarios
- more gameplay code refactoring
- fixed an issue that prevented custom external livery from being applied on a customized and saved user car
- during a race session, returning to pit will now penalize the player also when they are in the pit lane – this is a fix for the player being able to skip time in pit after teleporting back to pit from near box
- added damage rate in assist settings (SP)
- mandatory pitstop requirements implemented – it will be a MP feature for the time being
- launcher updated too, pit window is selectable in timed races above 20m of session length
- online leaderboards with hotlap/hotstint events
- added Special Events
- For Hotlaps, you will be able to select drivers around you on the leaderboard via the MFD and drive against their delta. Your own reference in the Delta widget will be replaced when another player is selected.
- For Hotstints, the same logic applies, but instead of replacing the delta, you will be seeing total gaps to the people around you crossing each sector line. So you will have more real-time feedback on how the stint is going, which is more engaging than only waiting for the total time.
- Both event types have a new optional function: Limited Attempts. This means that you can practice for an event as much as you want, but you can only have X amount of recorded attempts that will be tracked by the leaderboard, to increase the pressure of such an attempt and recreate a more race-like situation.
- hotstint leaderboards now show the storyboard data for selected entries once the selection event is triggered
PHYSICS/HANDLING
- updated tyre model for racing slicks – deployed on GT racing cars
- fixed some issues with AWD clutches
- fixed AWD not respecting various lock controllers
- SF25 wet setup now defaults to wet tyre and not inters
- fixed GT3 RS launch control rpm
- improved LSD differential simulation
added LSD friction faces to car setup - throttle model improvements on newly released cars, to be expanded to all content in continuation
INPUT/CONTROLS
- optimizations in the input system
- new default input definitions
- MFD page defaults to leaderboard in SEs
- FFB device recovery on disconnect/alt-tab (DirectInput, Fanatec, Logitech, Thrustmaster). Expected: FFB comes back by itself within ~1 s after alt-tab, USB unplug/replug, or base power-cycle.
- TrueForce/FullForce audio: FullForce DSP now uses the filtered signal with clamp; Logitech TrueForce gets a 350 Hz low-pass, gain from settings, and DSP reinit when the wheel handle changes. TrueForce now survives reconnecting.
- FFB output shaping: added linearization LUT loaded from file.
- LUT file: ffb.lut in the game’s SavedGame folder, input|output per line.
- ffb shaping fixes
- fixed a reconnection recognition issue with Fanatec devices
- fix for automatic shifter not being functional when H-shifter inputs are set
RENDERER/GFX
- renderer optimizations
- wind now has graphical representation
- fixed shadow factor gone missing on windshield effects
- added temporal dithering that works better with DLSS and FSR
- shadow receiver culling optimization. Expected result is that shadow now costs less than before. Available only in mono view.
- vehicle/cockpit cubemaps and mirrors optimization
- windshield material optimization
- exposure fusion added: a new feature that mimics how the human eye sees compared to a camera
- updated the View Settings page to allow users to modify their exposure bias, exposure fusion, and post-processing presets directly on track with live preview of changes taking effect in the background
- fixed TV camera jitter during replays/broadcast footage
