2025 Season 4 Patch 3 Release Notes \[2025.10.16.01]

[p]This Patch Release contains important updates as well as fixes for issues with the 2025 Season 4 Release.[/p][p]

[/p][h3]Special Demo Drive Note:[/h3]

[p]During this maintenance period, there will be intermittent connectivity to the Demo Drive launching/setup service for roughly the first 30 minutes of downtime.

iRacing Arcade is zippy bumper cars from the folks behind the simmiest racing sim ever to sim racing simishly

iRacing's always scared me a bit. Not just because you pay for it with a subscription that I've never felt committed enough to proper online sim racing in one place to sign up for, but because it's serious. No giggling allowed. Obey the track limits, spend hours playing around with damper setups, do not touch my bumper or I'll call three different police forces level of serious. A 42 page-long official sporting code doc for members level of seriously serious.

iRacing Arcade, its new sibling with a Steam Next Fest demo, is thankfully not as serious.

[/p][h2]SIMULATION:[/h2][p]--------------------------------------------------------------[/p][p]
[/p][h3]User Interface[/h3]

[p]The new Sim UI is here![/p]
[p]The new Sim UI is a complete re-architecture and rebuild of the in-Sim user interface, built from the ground up on powerful modern technology and an all-new framework. [/p]
[p]The initial experience has been crafted to function in a familiar way, with a fresh new look made possible by its modern rendering capabilities, along with multiple advancements in functionality and features, including:[/p]
- [p]Black Boxes: These now have minimized and expanded states. The Relative and Standings boxes display additional data.[/p]
- [p]Sim Options redesign: Options have had a significant reorganization, including the merging of the Replay and Driving graphics options. We’ve also added a clickable table of contents down the left-hand side, and to the right, we’ve added more information to explain the setting.[/p]
- [p]Alt-K to move UI: When pressing Alt-K to move elements around, you’ll find an additional toggle control to enable/disable all moveable elements, so now it’s easier to visualise those elements which normally only display when activated (such as flags and penalty notices).[/p]
- [p]Virtual Mirror size control: Via Alt-K, you can now also select the size of your virtual mirror from a drop-down menu.[/p]
- [p]Real-world clock: You now have access to your local wall-clock time via the F1 menu and also via an optional dedicated widget. This widget can be toggled in the Settings under the Interface tab in the On-Screen Displays section (Real Time Clock).[/p]
- [p]Camera Tool redesign: The Camera Tool is now accessible via a dedicated button found on the Session screen, and the tool itself is now more logically presented following a design update. The Ctrl-F12 binding is still available to toggle the Camera Tool.[/p]
- [p]Tooltips: The vast majority of controls now display tooltips when you mouse over them.[/p]
- [p]UI scale and opacity can now be adjusted while editing the layout or in Settings under the Interface tab in the Scaling & Opacity section.[/p]
- [p]All widgets can be made visible through a simple checkbox, and if you decide you don't like your changes, a convenient reset button is available. We've also made the UI editing mode easier to find, with some buttons to help you get started configuring.[/p]
[p]We are very excited about the future of the new Sim UI, and we want feedback about your experience, including what new features you want to see and how it should evolve. Additionally, if you experience any problems, we’d like to hear from you as well. To facilitate this, we have created a new Forum for providing feedback for the in-Sim UI, and encourage you to share your thoughts:[/p]

- [p]You may now use "!remove #N" with N being the full car number, provided that car only has a single declared driver. In that situation, that team’s one-and-only driver will be removed.[/p]

[p]
[/p][h3]Dynamic Track Model[/h3]

[p]Improved the simulated weather and time effects on the track before the first session begins to more accurately set the stage for the event.[/p]

[p]
[/p][h3]Damage Model[/h3]

[p]Adjusted the damage threshold where scrape textures begin to appear on vehicles.[/p]

[p]
[/p][h3]Graphics[/h3]

[p]For OpenXR VR devices that support the “XR_EXT_eye_gaze_interaction” extension, we have added support for Dynamic Foveated Rendering. There are two new related settings, one is “Allow Eye Tracking” and the other is “Show Eye Tracking.” The foveated rendering also requires an nVidia GPU RTX2000 series or better. [/p]
- [p]Dynamic Foveated Rendering renders each eye at a lower resolution and then renders a higher-resolution inset wherever it detects that each eye is looking, resulting in a stereo image with less resolution around the edges and more resolution where you are actively looking.[/p]
- [p]Important Notice: The SteamVR runtime does not support eye tracking properly for some HMDs For instance, you must select the Pimax/Varjo OpenXR runtimes for those headsets for better results.[/p]
- [p]Not all VR headsets/runtimes support this capability. Check your hardware specs to verify.[/p]
- [p]- - KNOWN ISSUE: The vertical axis for eye-tracking is currently inverted with this release. We suggest disabling the eye-tracking for now, and using fixed Foveated (Options > Display > VR) until we check our developers’ glasses prescriptions and release a fix![/p]
[p]Texture compression algorithms have been updated to provide higher quality visuals throughout the Sim, better GPU performance, and slightly shorter loading times.[/p]

[p]
[/p][h3]Audio[/h3]

[p]A new camera tool has been added, which allows for adjustments to the microphone offset.[/p]
[p]The limits of the listener controls in the camera tool have been adjusted.[/p]

[p]
[/p][h3]Spotter[/h3]

[p]Added a new spotter message: "Pitting now for fuel will get us to the end of the race."[/p]
[p]New spotter messages have been added for Time Trials, including:[/p]
- [p]“You need to complete X laps for this Time Trial.”[/p]
- [p]“You had an incident. Your lap count has been reset.”[/p]
- [p]“You’ve completed the laps needed for this Time Trial.”[/p]
[p]Added variants for a few spotter messages, including:[/p]
- [p]“We need more laps for fuel data.”[/p]
- [p]"We’ve got good fuel data."[/p]
- [p]"You have enough fuel to finish the race."[/p]
- [p]"Remember, you need to pit for more fuel."[/p]
[p]Fuel-related Spotter messages will no longer play during Time Trials.[/p]
[p]The Italian spotter packs have been updated.[/p]
[p]The Spanish spotter packs have been updated.[/p]
[p]The Portuguese spotter packs have been updated.[/p]

[p]
[/p][h3]Controls[/h3]

[p]For force feedback, softened the profile of rumble strips in an effort to reduce the audible noise they produce in the 360Hz force feedback channel.[/p]
[p]Adjusted the dead zone on the Logitech G27 Wheel.[/p]
[p]The latest Fanatec API has been updated. This fixes a random rare lock-up that could occur for some users.[/p]
[p]A new variable, \[TrueForce] trueForceSetGain= 1, has been added to the “app.ini” file.[/p]
- [p]This value lets users turn off the auto setting of TrueForce gain to 100% when the Sim launches. This is helpful for users who use the wheel tuning menu to adjust the feel of TrueForce, rather than the built-in TrueForce gain hotkeys.[/p]

[p]The Moza API has been updated, which fixes an issue where the wheel could become unresponsive after a period of time.[/p]

[p]
[/p][h3]Auto-Fuel[/h3]

[p]Fixed an issue where auto-fuel could silently edit the fuel value even when the system was disabled.[/p]

[p]
[/p][h3]Replays[/h3]

[p]Slightly lowered the chase camera angle to allow better visibility with wide aspect ratios.[/p]
[p]Fixed an issue where the Simulator could sometimes crash when attempting to save Replays.[/p]

[p]
[/p][h3]Active Reset[/h3]

[p]Fixed an issue where Active Reset would sometimes cause cut course slowdowns.[/p]

[p]
[/p][h3]Telemetry[/h3]

[p]Two new Boolean variables have been added: "PitRepairNeeded" and "PitOptRepairNeeded", that will be true when your car takes damage and needs mandatory or optional repairs.[/p]

[p]
[/p][h3]Sporting Code[/h3]

[p]A handful of updates have been made to the Official iRacing Sporting Code, including:[/p]
- [p]Track debris is now mentioned for Yellow Flags.[/p]
- [p]Information surrounding the Connection Black Flag has been added.[/p]

[p]A new Sports Car, the Aston Martin Vantage GT3 EVO, is now available for purchase and use within iRacing![/p]
[p][/p]

[p]Carrying on a long line of sports cars produced by the iconic British manufacturer, the Aston Martin Vantage GT3 first took to the track in 2019. Its EVO variant was unveiled in 2024, both as a new build and an upgrade kit for the original car. It features significantly revised aerodynamics—especially in the nose area—and suspension from its predecessor. Under the hood, it’s powered by a twin-turbo 4.0-liter V8 that can produce up to 600 horsepower depending on regulations. Wins for previous Vantage entries at Le Mans, Daytona, and Spa have proven a tall order to follow, but success has continued with the GT3 EVO model. Perhaps its biggest early triumph came in the 2024 24 Hours of Spa, won overall by Comtoyou Racing by more than 30 seconds; in 2025, it added a Gold Cup division win with Verstappen.com Racing, whose lineup included former iRacing Nurburgring 24H winner Chris Lulham.[/p]

[p]NEW CAR![/p]
[p]A new Formula car, the Dallara IL-15, is now available for purchase and use within iRacing![/p]
[p]The series currently known as INDY NXT debuted in 2002 as a feeder series for the then-Indy Racing League, and it took on its current name in 2023 when it was acquired by Penske Entertainment. It has become highly effective at graduating drivers into the premier NTT INDYCAR Series, with future INDYCAR champion Josef Newgarden and fellow stars Patricio O’Ward and Kyle Kirkwood each using INDY NXT titles to springboard their future successes at the highest level. INDY NXT’s weapon of choice is the Dallara IL-15. Introduced in 2015, it features 450 base horsepower (plus an additional 50 with push-to-pass) coming out of a turbocharged 2.0-liter inline-four. The car received updates in 2021 including a halo for driver safety and new engine tuning by AER to run a full season without a rebuild. The latest update to the car came in 2023, when Firestone took over as tire supplier after Penske’s acquisition of the championship.[/p]

[p]NEW CAR![/p]
[p]A new Sports Car, the Ford Mustang GT4, is now available for purchase and use within iRacing![/p]
[p]Unveiled in the summer of 2023 for use in 2024 and beyond, the current Ford Mustang GT4 has become a popular choice in the category around the world. If its uniquely American style wasn’t enough to sell the skeptics, its immediate results were; in its first race weekend, part of the IMSA VP SportsCar Challenge opener at Daytona, KohR Motorsports’ Luca Mars swept both races on the way to scoring the class title later that year. As with many other manufacturers, Ford built the Mustang GT4 for the use of customer teams, saving its factory-backed efforts for the GT3 division and higher. Developed in conjunction with Multimatic Motorsport, the Mustang GT4 boasts a 5.0-liter Coyote V8 built by Ford Performance in Michigan. Other features include Multimatic DSSV dampers, natural fiber body panels, and a GT4-specific aero package.[/p]

[/p][h3]Autódromo Hermanos Rodríguez (Mexico City)[/h3]

[p]NEW TRACK![/p]
[p]A new track with SEVEN configs, including both Sports Car and Oval configs, Autódromo Hermanos Rodríguez (Mexico City), has been added to iRacing![/p]
[p]Designed as a thesis study in the early 1950s by student Oscar Fernandez, Autódromo Hermanos Rodriguez has hosted many of the world’s most iconic racing series over its storied history. From what is now known as the Mexico City Grand Prix to the NASCAR Cup Series’ first-ever event outside of the United States in 2025, the track has evolved numerous times over the years to accommodate different vehicles and advances in driver safety. Most of Autódromo Hermanos Rodriguez’s layouts, including the current 2.67-mile Grand Prix layout, feature a lengthy front straightaway into a right-angle, right-handed first corner. Top-tier open-wheel cars can reach a top speed exceeding 220 miles per hour before this initial braking zone. Also unique to the venue is the Foro Sol section, which sends drivers through baseball stadium seating; this same area of the track has also been used for the 2019 Race of Champions. The Autódromo also boasts a flat, one-mile oval that can both host stock car races and serve as the basis for shorter road racing layouts.[/p]
