Full 2021 Season 3 Release details are below.

iRACING UI:

--------------------------------------------------------------

Find Sessions for Content

Each Car and Track info window now features a new tab, Find Sessions. To get to the Car or Track info window from anywhere in the UI, click the three dots icon next to a content and select “Car/Track Info”

- - This tab is separated into three sections which each display a list of all available sessions that use this piece of content. This includes: Official Sessions, Hosted Sessions, and Time Attack.

- - From this window, you can browse all available sessions, navigate directly to the associated Series to learn more, or even join the sessions right away! You may also use select Filters and Tags to curate the list of available sessions to your tastes.

- - This tab is available for ALL pieces of content, even items you do not own. This makes it very easy to learn how a piece of content is used before you purchase it, and it allows you to jump right into events using a favorite piece of content.

Interface Images

All images in the iRacing UI that previously showed a Member's in-Sim paint scheme will instead now show any available custom paints present on the file system.

- - This applies to cars, suits, and helmets.

- - This should work for a Member's own paints as well as displaying other Members’ paints. For example, seeing another Member's custom helmet on their profile.

- - As a reminder, custom paints should be placed in the “My Documents/iRacing/paints” folder. Helmets and suits are in the base directory and cars are in their respective subdirectories.

Car images will automatically be loaded when the iRacing UI launches.

- - This should minimize the appearance of car images “popping in” when a large number are shown on a page at once.

Series Racing

Fixed an issue where the Time of Day setting was not being correctly preserved when creating Test Drive events or Hosted Sessions from a Series event.

Team Racing

For the Declare Drivers feature for events using the “Drive Fair Share” rules, Teams may now update their pending Declared Drivers list prior to the start of the Race Session.

- - Drivers in the list must still be team members that are eligible to drive for the session.

- - The Declared Drivers can only be altered for sessions which have not launched and are currently open for registration.

- - The list cannot be changed for Practice or Hosted Sessions, or Race Sessions after the Session starts.

- - Any team admin or the team member who registered the team can update the list of declared drivers.

Hosted Racing

For Open Practice Only events, multiple setups may now be selected for use. For example, this allows users to select both Qualify and Race setups for practicing.

Fixed an issue where users were unable to change the selected track for their Session if they had enabled Short Parade Laps prior to attempting to change the track.

Filtering the available Hosted Sessions to achieve no results now correctly displays the warning “No Data”.

AI Racing

Some additional race options have been added for AI Racing, including:

- - Short Parade Laps

- - Wave Arounds

- - Do Not Count Caution Laps

Fixed an issue where loading into an AI Session using a default class-based Opponent Roster would break the loading screen.

Paint Shop

Textures for driver heads with ponytails have been updated.

The McLaren MP4-30 interface model has been updated to better match the in-Sim version.

The RYCO logo has been updated.

General

Fixed an issue where new users could load into an empty user interface.

MEMBERSITE:

--------------------------------------------------------------

Auto-Launching The UI

The home page no longer half-loads when you select to cancel opening the iRacing UI.

Promotions

Fixed a button layout issue.

FORUMS:

--------------------------------------------------------------

New Forums

New iRacing Forums: https://forums.iracing.com/

All new posts, discussions, and announcements from iRacing will only be made in our new forums.

The original Membersite forums will remain available through June 23rd. Then they will enter a read-only state for the foreseeable future.

The Private Message system will also remain intact until further notice.

We will be providing an OAuth2 API for third-party development in the near future as well.

SIMULATION:

--------------------------------------------------------------

Connectivity

Improved the reporting and handling of dropped connections.

- - These changes will NOT fix bad network connections, but the messages shown as a result of these changes may give a bit more detail as to what went wrong. In some situations the amount of time it takes for a dropped connection to be cleared will be reduced, so a user may be allowed to reconnect more quickly.

Cars

Up to 8 different car models may now be used when creating Hosted Sessions.

Engine oil cooling has been adjusted to increase temperatures at lower engine RPM. Higher engine speeds are not impacted by this change.

Tracks

All track collision meshes have been regenerated.

A variety of visually updated tire stacks and tire wraps have been added throughout iRacing tracks. This rhyme was unintentional.

Race Control

A new mode of off-track detection has been created, “Four-Tire Detection”.

- - Our current off-track detection system checks for whether or not half or more of your vehicle has traveled beyond a racing surface boundary. The new four-tire detection system checks for whether or not all four of your vehicle tires have traveled beyond a racing surface boundary. Since the four-tire detection system requires more of your vehicle to be off of the racing surface before administering a penalty, this system is more forgiving.

- - The four-tire detection system will be deployed on a case-by-case basis. With this initial release, the four-tire detection system is currently active at some areas of Circuit de Spa-Francorchamps and Red Bull Ring. The four-tire detection system will be applied to additional tracks and areas as we continue to collect feedback and data from our members.

- - Any track that is utilizing the four-tire detection system will feature a new “Rules” tab in the in-Sim interface. This new tab will detail where the four-tire detection system is active at the track.

Fixed an issue where closed pit exits could cause a black flag for drivers on a parade lap when the field starts in pit lane.

Dirt Racing

Opponent tires on dirt surfaces should appear to be touching the ground better, particularly for slopes, bumps, and divots.

All dirt versions of stockcar tires have been reverted to an earlier version.

- - This change affects the following vehicles:

- - - - ARCA Menards Chevrolet Impala

- - - - NASCAR Cup Series Class Cars

- - - - NASCAR Gander Outdoors Series Class Cars

- - - - NASCAR Next Gen Series Class Cars

- - - - NASCAR Xfinity Series Class Cars

- - - - [Legacy] NASCAR Cup Series Class Cars

- - - - [Legacy] NASCAR Nationwide Chevrolet Impala - 2012

- - - - [Legacy] NASCAR Truck Chevrolet Silverado - 2008

- - - - [Legacy] NASCAR Xfinity Series Class Cars

Rallycross Racing

Fixed an issue where the high rpm launch rev limit in the rallycross cars would prevent the gearbox from downshifting lower than 3rd gear when stationary.

AI Racing

AI Drivers are now able to pilot the following additional vehicles:

- - Porsche 911 GT3 R

- - Street Stock

AI Racing is now available on the following additional track configurations:

- - Lanier National Speedway - Asphalt

- - Lime Rock Park - Chicanes

- - TURN ONE: Horror Stories and What you can Learn

- - Alex Foster’s Guide to Pit Stall Entry & Exit

- - How I Learned to Stop Worrying and Love the Parade Lap

- - The Sides of your Car and the Things that are There, A 2021 Treatise on Lateral Perception

- - Handle With Care - Preventing Rollovers at Low Track Temperatures

- - Three Essential Steps for Recovering your Race-Line

- - Locating Pit Lane Entry and Exits in the Wild

- - Translating Track Corners to Wheel Rotation

AI Vehicle parameters have been updated to improve their correlation to a user vehicle for the following vehicles:

- - NASCAR Cup Series Class Cars

Race Admins

A new race admin command has been added that can modify the number of laps a Caution or Parade will be:

- - !pacelaps (or !p for short) <+n|-n|n>

- - - - Add +n laps to caution length, or remove -n laps from caution length, or set caution to "n laps to green" at next crossing.

- - - - The caution lap length can't be adjusted until the first full caution lap is completed, since the caution length is not finalized until then.

- - - - The number of parade laps may be adjusted immediately, just as cars start driving.

- - !yellow is primarily intended for throwing a caution, but can still be used to delay an upcoming start/restart by 1 lap if used during the 1 to Green lap, which would be equivalent to !pacelaps +1.

New Damage Model

The New Damage Model has been enabled for the following vehicles:

- - Formula Vee

- - Street Stock

The duration during which detached parts from opponent vehicles are collidable has been shortened significantly.

- - This should help reduce the possibility of hitting debris generated from local estimates of collision damage in a high latency environment.

- - The duration for yourself and your own car parts has not been reduced.

Tire side-wall properties for some vehicles have been adjusted to differ from tire tread properties. These changes should allow more realistic tire-to-object and tire-to-tire contact based on the part of the tire(s) making contact.

- - These tire property changes have been enabled for the following vehicles:

- - - - ARCA Menards Chevrolet Impala

- - - - Audi RS 3 LMS

- - - - Dallara IR18

- - - - Indy Pro 2000 PM-18

- - - - Skip Barber Formula 2000

Fixed an issue where some cars were getting repeatedly reset in the pits, and appeared to be bouncing around as a result.

- - When a spring damper was broken it was possible the wheel could hit the hyper extension limit if it was set fairly low. Whenever the hyper extension limit was exceeded the code was resetting the car while in the pits, without fixing the hyper extension, resulting in a bouncing-reset loop.

Some curbs used on Rallycross tracks have been updated to prevent devastating blows to cars utilizing the New Damage Model.

Original Damage Model

Fixed an issue where vehicles that have the capability to run the New Damage Model were not having damage scrape textures appear when running with the Original Damage Model.

Rendering

Fixed an issue where specular highlights were not rendering brightly enough, especially on the track surfaces and cars.

Fixed an issue where the illumination of the world often flickered in brightness as the sun moved, especially during sunsets.

Visual Effects

Smoke may no longer be disabled via the graphics options.

Tire smoke and dust have received an overhaul!

- - Smoke and dust volumes and sizes have been tuned based on the moisture levels in the environment.

- - Smoke blending has been improved.

- - More lingering dust should be visible towards the end of a dust-cloud's life cycle.

- - Dust particle volume has been increased during dirt racing events.

Spark effects have been updated.

Backfire and exhaust effects have been optimized.

The average track temperature for generating heat haze has been updated to utilize data from the dynamic track system.

Water shaders have been updated for more realistic behaviors including slower speeds along the shores and improved roughness. Water reflections have also been improved

Fixed an issue where smoke effects were not appearing for the player car during Lone Qualify Sessions.

Audio

Road debris sound levels and variations have been improved.

Pace Car

The Sedan Pace Car may now be selected for use at any and all track types.

- - The pace car driver has completed a rigorous course in stunt driving with this vehicle, and has passed all final exam maneuvers with flying colors.

After some extensive tutoring on the states of matter, the Pace Car driver is now less apt to drive through solid walls.

Fixed an issue where the Sedan Pace Car's headlights would incorrectly be lit while parked at night tracks.

Backfire effects have been removed from the Sedan Pace Car. :’(

Spotter

The Italian spotter packs has been updated, thanks to Renzo A. Olivieri and Marco Arcidiacono.

Cameras

More camera tool controls can now be mapped to an analog axis on a joystick.

The “show camera” mode is no longer persistent, and will now turn itself off on the next restart of the Sim.

Blimp camera option minimum allowable values have been reduced to nearly 0.

Fixed an issue with cameras' "aim at group" logic that could sometimes cause a camera to shake or shudder.

Controls

Joystick calibration routines have been updated so that all control types should be able to calibrate, including combined pedals that operate in the opposite direction of the industry norm. Mapping separate functions to each half of a joystick's axis should be greatly improved as well.

Support for the display on the new Thrustmaster SF1000 wheel has been enabled. You can turn this on and off with the “Control LCD wheel displays” checkbox in the Sim Options menu. Tire data is not sent to the wheel, other than core temperatures and wear being updated when you stop in your pit box. This matches the rest of the Sim where no real time tire info is displayed. To make this work you will need to be on the latest version of the Thrustmaster driver (2.TTRS.2021 rc29), and you will need to update your drivers and firmware to enjoy the full support of SF1000 in iRacing.

Logitech keyboard back-light support has been re-enabled.

- - You will need the latest version of Logitech GHub or Logitech Gaming Software.

Support has been added for the Razer Chroma RGB Controller and other Chroma Link enabled devices in the Razer Chroma keyboard lighting effects.

Fixed an issue where the second brake and second throttle controls were disabled for some vehicles.

Fixed an issue where some analog controls could never achieve a “0 input” value.

Telemetry

A new session string value, “CarClassEstLapTime” has been added.

- - This value indicates the estimated lap time for every car in the session. This value matches the existing value, “DriverCarEstLapTime” entry for the player's car.

New telemetry values, “CarIdxFastRepairsUsed” and “PlayerFastRepairsUsed” have been added.

- - These values log how many fast repairs each participant has used in the current session. These only report on sessions where there is a limit on the number of fast repairs.

ABS brake engagement is now logged to telemetry as the boolean, "BrakeABSactive".

- - This value is true if either the car physics ABS is active or the Driving Aid ABS is active. The car physics ABS now drives the LFE bass shaker just like the driving aid did previously.

- - NOTE: This is currently only available on the following vehicles:

- - - - Audi R8 LMS

- - - - Audi RS 3 LMS

- - - - BMW M4 GT3

- - - - BMW M4 GT4

- - - - BMW Z4 GT3

Simulator performance meters may now be displayed via telemetry:

- - FPS = FrameRate

- - R = CpuUsageFG

- - G = GpuUsage

- - L = ChanLatency, ChanAvgLatency

- - Q = ChanQuality, ChanPartnerQuality

- - C = CpuUsageBG

- - S = ChanClockSkew

- - P = MemPageFaultSec

- - F = SteeringWheelPctTorque

- - - - You can find more information on these values here: https://support.iracing.com/support/solutions/articles/31000133494-meter-box-f-key-in-game-

New telemetry messages have been enabled that allow a remote program to start/stop video capture and take screenshots.

- - New telemetry value: “VidCapEnabled” that is true if the video/screen shot system is enabled.

- - New telemetry value: “VidCapActive” that is true if the video system is currently recording a video to disk.

Fixed an issue with variable, “CarIdxP2P_Status” where all 64 entries were not showing up correctly.

For the Original Damage Model, rear wing damage now increases aerodynamic drag until the wing comes off. If the wing is removed, aerodynamic drag decreases. The downforce loss due to rear wing damage has also been increased to discourage intentional removal of the wing.

Fixed an issue that could cause pedals to vibrate constantly when driving this car.

Porsche 911 GT3 R

NEW CAR!

- - A new road car, the Porsche 911 GT3 R, is now available!

- - - - GT3s have proven to be some of the most popular road racing cars in the world in recent years, and few brands have quite the road racing pedigree of Porsche. It should stand as no surprise, then, that the Porsche 911 GT3 R is both a beloved and successful piece of kit. Immediately successful out of the gate thanks to a win in its first attempt at the Bathurst 12 Hour, you can find the 911 GT3 R running at the front of the field everywhere from the IMSA WeatherTech SportsCar Championship to the Intercontinental GT Challenge. The 4.0-liter flat-six boxer engine produces a whopping 543 horsepower, more than enough to propel you to the front of the pack!

SCCA Spec Racer Ford

FULLY UPDATED FREE CAR!

- - The SCCA Spec Racer Ford has been fully updated to the Gen3 version!

- - - - This change includes a brand new tire spec, new digital dashboard, increased horsepower, reduced vehicle weight, and a 6-speed sequential gearbox.

- - - - The notion of competing in a class of identical race cars so that driving skill is paramount and the size of one's checkbook doesn't matter is second nature to iRacers - it's a central theme of the iRacing.com community. But the concept, originally borrowed from one-design sailboat racing, is rapidly gaining currency in motorsport with classes ranging from Spec Miata to Star Mazda and even to IndyCar, where every team races the same chassis/engine combination. The original successful one-design auto racing class, first introduced a quarter-century ago in Sports Car Club of America amateur racing and still going strong today (after a few universally-applied modifications along the way), is Spec Racer Ford. Manufactured and marketed by SCCA Enterprises (a subsidiary of SCCA, Inc.) the Spec Racer Ford is a purpose-built sports/racing car. With more than 850 cars manufactured, it is one of the most prolific dedicated racing cars in the world, and has served as the launching pad for a number of drivers who have gone on to substantial success in motorsport, including racer-turned-broadcaster Dorsey Schroeder. The car was developed and originally manufactured by Renault/Jeep Sport USA. An initial proof-of-concept was assembled using the longitudinal engine-transmission package from the Renault LeCar, but that vehicle was written off in testing at Road Atlanta and a more practical successor was then developed using the transverse Renault/AMC four-cylinder Encore powertrain. Known as the Sports Renault, that vehicle, which looks virtually identical to today's SRF, made its debut in SCCA club racing in 1984. The car was sold to competitors in kit form, but to facilitate technical support and give buyers a turn-key option, SCCA established a regional network of sales and service dealers, a concept that under the name Customer Service Representatives, remains a key element in the success of the class today. With AMC sold off to Chrysler and Renault sponsorship withdrawn in 1989 after a fleet of hundreds of cars had been put into service, the class was renamed Spec Racer and the club took over responsibility for manufacturing and supporting the car. Five years later, with the original Renault engines and transmissions growing scarce, SCCA began a program to gradually shift the fleet to a 1.9-liter four-cylinder Ford engine and five-speed transmission, and for several years the club supported two classes racing alongside one another, the original SR and for newly manufactured cars and ones that had been converted, SRF with 105 horsepower (10 more than the Renault) and a top speed of 135 mph. Today only the SRF is raced in SCCA.

VW Beetle Lite

NEW FREE CAR!

- - A new Rallycross car, the VW Beetle Lite, is now available!

- - - - A little buggy that packs a big punch, the Volkswagen Beetle Lite crosses asphalt and gravel effortlessly. An adaptation of the Beetle, that dominated rallycross in North America for most of the past decade, the Beetle Lite’s engine has been reduced to 300 horsepower to enable drivers to learn the skills that will make them quick in rallycross without being overpowered by the turbo power of the Supercar. This Volkswagen Beetle features a retro form that pays homage to the original Volkswagen Type 1, the longest-running and most-manufactured car of a single platform ever made.

Nashville Superspeedway

NEW TRACK!

- - A new concrete oval, Nashville Superspeedway, is now available!

- - - - In 2001, national-level NASCAR racing returned to Nashville when the 1.333-mile Nashville Superspeedway opened and played host to what are now known as the Xfinity and Camping World Truck Series for the first time. Over its first decade, the track became a staple of the schedule for both series, expanding each to two events, while also adding IndyCar racing for the first eight years of its existence. However, without a NASCAR Cup Series date on its calendar, 2011 proved to be the track’s final season, and it would shut down after choosing not to seek NASCAR sanction for 2012. How times have changed. In June 2020, NASCAR awarded Nashville Superspeedway a Cup Series date for 2021, effectively bringing the track back to life. For the first time, it’ll host all three national NASCAR series in June 2021. Like Dover International Speedway, its sister track, Nashville features a concrete racing surface that will present a unique challenge to the many real-world racing stars who will take it on for the first time. You’ll find yourself facing those same obstacles as you attempt to handle the track’s high speeds on iRacing!

Red Bull Ring

NEW TRACK!

- - A new asphalt road course, Red Bull Ring, is now available!

- - The Red Bull Ring features three configs; Grand Prix, National, and North.

- - - - The Red Bull Ring's origins date back to 1969, when the Österreichring opened to replace the Zeltweg Airfield as host of the Austrian Grand Prix and attempt to draw the Driver's World Championship back to the country. That mission was successful just one year later, and the event became a staple of the series until 1987. The track was completely rebuilt in the mid-1990s and rechristened the A1-Ring, which enabled it to return to the circuit from 1997 to 2003. After a period of uncertainty that followed the demolition of the grandstands and pit buildings in 2004, circuit owner Red Bull began its reconstruction of the track in late 2008 and gradually added both modern and vintage events over the years, culminating in the return of the Austrian Grand Prix in 2014. In 2020, with the COVID-19 forcing a rework of the schedule, the Red Bull Ring became the first circuit to ever host back-to-back rounds to open a Formula 1 season, as well as the first European venue to host the opening round of the season since 1966.
