Assetto Corsa Competizione (ACC) received version 1.10.4 on December 22, 2025. This update introduces the official 2025 Fanatec GT World Challenge season as a free addition for PC simracers on Steam. While several major media outlets like Traxion.gg have reported this as the final content drop for the simulation, the official notes from Kunos Simulazioni does not use the word “final.” Instead, the developer describes it as a substantial update to align the game with the current real-world racing season.
New 2025 Content and Driver Rosters
The update adds a total of 95 official liveries to the simulation. This includes 86 designs for the GT World Challenge Europe and 9 for the GT World Challenge America. Accompanying these liveries is a revised driver set that reflects the actual lineups for the 2025 season. The update also integrates the 2025 GTWC Europe season as a standalone single-player championship mode. It is important to note that this update focuses on liveries and rosters rather than new car models; vehicles like the Aston Martin Vantage GT3 Evo and the Ford Mustang GT3 are not included in this patch as the underlying 3D models were not developed for the ACC engine.
Verstappen.com Racing and Emil Frey Ferrari
A major highlight of this update is the inclusion of the Verstappen.com Racing Ferrari 296 GT3 operated by Emil Frey Racing. For the 2025 season, Thierry Vermeulen and Chris Lulham competed in the GT World Challenge Europe Sprint Cup using this car, eventually securing the Gold Cup team and driver titles. While Verstappen.com Racing has recently confirmed a multi-year partnership with Mercedes-AMG starting in 2026, the 1.10.4 update provides the chance to race the Ferrari 296 GT3 in its championship-winning 2025 colors. This is the definitive version of the Verstappen-backed Ferrari program before the team transitions to the Mercedes-AMG GT3 platform and shifts its technical partnership to 2 Seas Motorsport for the 2026 campaign.
Technical Improvements and System Changes
Version 1.10.4 implements GEN5 temporal anti-aliasing (TAA), which targets long-standing visual artifacts such as shimmering and ghosting in the Unreal Engine 4 architecture. This change improves image clarity on high-resolution displays. Additionally, the TV camera system has been adjusted to provide a more authentic broadcast perspective during replays. A critical technical detail for this update is the potential reset of the menuSettings.json file. Drivers will likely need to reconfigure their UI preferences and controller settings upon their first launch after the patch. The Balance of Performance (BoP) has also been revised to ensure the 2025 grid remains competitive for both league racing and official SRO esports events.
Platform Availability and Compatibility
Currently, the 1.10.4 update is available only on PC via Steam. For PlayStation 5 and Xbox Series X|S users, the 2025 season content is expected to arrive in 2026 following the platform certification process handled by Untold Games and 505 Games. It is confirmed that the PlayStation 4 and Xbox One versions of the game will not receive this update. Official support for eighth-generation consoles ceased during the version 1.9 cycle because the hardware is unable to support the latest physics calculations and graphical refinements like the GEN5 TAA system. This creates a technical split where older consoles remain on a legacy version while current systems continue to receive seasonal parity.
Context Within the Kunos Universe: Assetto Corsa EVO and Rally
The shift in development focus for ACC is clearer when looking at the broader Kunos portfolio in late 2025. Assetto Corsa EVO, the next generation of the franchise, reached version 0.4 in early December, introducing features like the Nürburgring Nordschleife and a dedicated ranked multiplayer system. Furthermore, Kunos has expanded its reach with Assetto Corsa Rally, which launched into Steam Early Access on November 13, 2025. Developed in partnership with Supernova Games Studios, AC Rally utilizes a specialized version of the Kunos physics engine designed for jumps and loose surfaces. This diversification confirms that while the core ACC team has transitioned to newer projects, the studio is actively managing multiple simulations simultaneously.
The Outlook for 2026
The official silence regarding a hard stop to ACC development suggests that the platform may still see maintenance in 2026. As long as ACC remains the official platform for GT World Challenge esports, further BoP adjustments and stability patches are a reasonable expectation. While version 1.10.4 is the most comprehensive update for the 2025 season, the lack of a “final” label from Kunos allows for the possibility of continued technical support and seasonal minor content as the 2026 real-world championships begin.
Massive Savings: Limited-Time 2025 Holiday Discounts
Drivers looking to enter the simulation or complete their collection can take advantage of a significant promotion currently active on Steam until January 5, 2026. The base version of Assetto Corsa Competizione is currently listed at a 75 percent discount, while the comprehensive bundle featuring all released car and track DLCs is reduced by 60 percent. This pricing represents a deeper discount than the game’s typical seasonal sales, providing the most cost-effective entry point to date for those wanting to experience the full 2025-spec grid before the offer expires on January the 5th 2026.
