Automobilista 2 V1.6.4.3 Update: Refining the Racing Experience

The V1.6.4.3 update for the racing simulator game Automobilista 2 builds upon the previous V1.6.4.2 release, further enhancing the gameplay with refinements to physics, AI behavior, vehicle setups, and overall performance. This update focuses on perfecting the driving experience, especially for the new Super Trophy Trucks (STT) class and its associated content. Whether you're using high-end sim racing hardware like the Fanatec Steering Wheel Monte Carlo Rally, ClubSport Pedals V3 Inverted, or the immersive ClubSport Racing Wheel F1 ® Ready2Race Bundle the update ensures that your setup delivers a more responsive and realistic racing experience.

The STT class and 12 dedicated layouts were introduced as part of the Adrenaline Pt2 DLC. The STT content in the latest update is now exclusive to players who own the Adrenaline Pt2 DLC or specific package deals. These DLCs give you access to the STT trucks and their content without additional charges. This update also includes performance and setup improvements for the STT vehicles, ensuring they perform optimally on the newly dedicated layouts. Sim racers can improve their truck skills by mastering countersteering.

The V1.6.4.2 update made significant strides by shifting the physics engine to use 4 CPU threads, improving game responsiveness. V1.6.4.3 continues this trend by refining the tire wear and thermodynamics for GTP and LMP2 tires. These tires now require more energy to reach their optimal temperature ranges and react more dynamically to weather conditions, particularly on wet surfaces. The update also improves particle rendering and shadow intensity, making stormy weather conditions look more realistic.

Both updates focus on refining tire performance, especially for wet surface behavior and slick compound sensitivity. In V1.6.4.3, further adjustments were made to cold tire behavior, particularly for GTP, LMP2, and GT3 classes. The new calibration ensures a more challenging and realistic racing experience, with narrower optimal temperature windows for tires, requiring players to manage their tires more carefully during a race.

V1.6.4.2 introduced several key AI improvements, such as better behavior during practice and qualifying sessions, with adjustments to help the AI navigate traffic more effectively. Additionally, wet conditions saw the introduction of the Wet Skill Scalar and Mistake Multiplier to fine-tune AI difficulty. V1.6.4.3 builds on these changes by further improving AI performance in cold and wet weather. The update adjusts lateral movement rates to prevent overly aggressive car movements, especially for GT vehicles, and revises AI racing lines at Daytona to reduce the likelihood of incidents.

In terms of vehicle updates, the initial March 2025 update focused on improving various aspects such as pit limiter displays, tire pressure settings, and aero changes. The V1.6.4.3 takes it further with specific tweaks to the McLaren 720S GT3 EVO, which received changes to its aerodynamics and default setup. The STT vehicles also received updates to their steering lock, and a setup reset is recommended to optimize handling. Additional fixes include improved FFB settings for the Audi R8 GT4 and visual improvements to the BMW M6 GT3 and BMW M8 GTE.

Track-specific changes have also been addressed in Adelaide’s pit lane apron, and Daytona’s apron now produces less dust when cars drive over it. For STT layouts, ramp positions on tracks like Monza and Spielberg have been updated to ensure smoother transitions for off-road racing.

Further improvements include physics refinements, AI behavior, tire dynamics, and vehicle setups. The update continues to enhance the overall gameplay experience, making Automobilista 2 a more dynamic and realistic racing simulation. With ongoing improvements to key aspects like AI, tire performance, and vehicle handling, the game remains a top contender in the racing simulation genre.
