2021 Season 3 Patch 5 Release Notes [2021.08.10.03]

SIMULATION:
--------------------------------------------------------------
Rendering
We have integrated SpeedTree into our simulation/game engine. SpeedTree is a 3D vegetation modeling and rendering system designed for films and real-time games. It provides our artists with tools to build location-specific trees and then quickly place them at our racetracks. The system is engineered to render these trees efficiently and with built-in level-of-detail (LOD) management, and has received specific customization to make it work optimally for iRacing's requirements. This feature is making its debut at Mount Washington and will be used more extensively in the future.

CARS:
--------------------------------------------------------------
Indy Pro 2000 PM-18
iRacing setups have been updated.

Subaru WRX STI
On-board engine and rev limiter sounds have been improved.
Windshield reflections have been updated.

TRACKS:
--------------------------------------------------------------
Mount Washington Auto Road
NEW TRACK!
- - Mount Washington Auto Road is now available as a pre-release track!
- - This Rallycross track includes two configurations, Hillclimb, and Descent.
- - Towering at 6,288 feet, Mount Washington is the highest peak in the northeastern United States and the sixth-highest mountain in all of North America. The Mount Washington Auto Road was completed in 1861, stretching 7.6 miles and climbing 4,618 feet from base to summit at an average gradient of 11.6%. The road is both open to private vehicles and guided tours, and "THIS CAR CLIMBED MOUNT WASHINGTON" bumper stickers are prevalent throughout New England. In 1904, the inaugural Mount Washington Hillclimb Auto Race was hosted. Held sporadically over the past century, the "Climb to the Clouds" is nonetheless the oldest auto race in the country. Its latest revival as a full-blown race came in 2011 as a tri-annual event, and each edition of the race since 1956 has seen a new record time set by the winner. The most recent record was set by Travis Pastrana in 2017. Mount Washington serves as iRacing's first-ever point-to-point hillclimb race - do you have what it takes to make it to the top?
- - Add the Mount Washington Auto Road to your digital landscape by purchasing it from the iRacing store today! https://members.iracing.com/membersite/ ... ?trkid=398

Wahoo!!! So stoked to see this being available so quickly (next build). I wonder what they will do with the older 991 now?

On the heels of the release of the Porsche 911 GT3 R in June, iRacing and Porsche are pleased to reveal that the Porsche 911 GT3 Cup (992) will also join the service in time for the 2021 Season 4 build in September. The latest generation of vehicle used in the global Porsche Supercup single-make competition joins a robust lineup of Porsche LMP1, GTE, GT3, and GT4 cars already on iRacing.

“iRacing is proud to welcome the new Porsche 911 GT3 Cup to the sim for September,” said iRacing executive vice president Steve Myers. “Our lineup of Porsche vehicles has always proven quite popular across special events, public series, and hosted races, and we expect the updated 911 GT3 Cup car to be similarly well-received among iRacers around the world.”

The Porsche 911 GT3 Cup (992) packs a 510-horsepower punch and introduces a fresh slate of upgrades from its predecessor. Besides an increase in power in its 4.0-liter flat-six powerplant, included in the evolution from the 991.2 generation model are a new chassis design with increased aluminum usage, double wishbone front suspension, a new electronic shift system, safety features, and more. The real-world version of the car made its debut in time for the 2021 Porsche Supercup season.

The Porsche 911 GT3 Cup (992) will hit the track on iRacing for the first time on September 4, with a special event featuring content creators competing in a fun-oriented race at Hockenheim. Tune in to twitch.tv/Porsche at 18:00 GMT (2PM ET) to watch the action. For more information on Porsche’s real-world and sim racing motorsports initiatives, visit http://motorsports.porsche.com.

I'm disappointed it isn't the updated AMG but hoping they have that waiting to release this build too.

NEW CONTENT! Ferrari 488 GT3 Evo
The latest GT3 to join iRacing’s road racing stable makes its debut in 2021 Season 4, as the Ferrari 488 GT3 Evo takes its place in the lineup with the new build. The Evo model will replace the previous generation Ferrari 488 GT3 in iRacing’s public road racing series, and will see its first on-track action in Week 13 series after the build is deployed on Wednesday.

The 488 GT3 was already one of Ferrari’s most successful sports cars of all time, but continued evolution is a hallmark of the brand’s continued success across all forms of racing. Such is the mindset that birthed the 488 GT3 Evo, a reworked version of the car that features a longer wheelbase, new engine management system, additional driver comforts including a new seat developed with Sabelt, aerodynamic adjustments, and more.

Like its predecessor, the 488 GT3 Evo pumps nearly 600 horsepower out of a 3,902 cc twin-turbo V8 powerplant, giving racers more than enough power to go for the win. The result is a proven GT3 platform that has taken the next steps towards further glory in the world’s biggest sprint and endurance championships.

The Ferrari 488 GT3 Evo will be available for purchase immediately after deployment of the iRacing 2021 Season 4 build

iRACING UI:
--------------------------------------------------------------
AI Racing in Hosted Racing
A new feature has been added to Hosted Racing: the ability to utilize AI Racing and AI Opponent Rosters!
- - Hosted Sessions now include the ability to add an AI Opponent Roster to the Hosted Session. This allows the Session Host to bring in AI Opponents to fill-in unclaimed entry spots for the Hosted Session, ensuring a full racing grid, and allows for multiplayer AI Racing. This feature may also be used in Hosted League Sessions!
- - You can see if a Hosted Session is utilizing an AI Opponent Roster by an “AI” icon on the Session, or by checking the Summary screen for the Session. During the Session and in the Race Results, AI Drivers are indicated with an [AI] tag, or a robot icon.
- - While a Hosted Session is running with AI Drivers, the AI Drivers are processed on the Session Host’s machine. This means the AI Drivers will share any connectivity issues experienced by the Session Host. This also means if the Session Host disconnects, the AI Drivers will disappear from the event until the Session Host rejoins.
Some notes about setting up AI Hosted Sessions:
- - Only Hosted Sessions that utilize AI-enabled content may enable AI Opponent Rosters.
- - Team events may not be created.
- - Heat Racing Events may not be created.
- - The “Avoid Me” option is available in the form of “Avoid Players”. This has also been updated in offline AI Racing.
- - The Session host may edit a pending Hosted Session that includes an AI Opponent Roster.
Some notes about AI Opponent Rosters:
- - An AI Opponent Roster of any size and makeup can be used for a Hosted Race.
- - AI Hosted Sessions can utilize an existing AI Opponent Roster, or one can be generated while the Hosted Session is being created.
- - When an AI Opponent Roster is enabled when creating a Hosted Session, the default number of AI Opponents to include in the Session is equal to half the size of the selected Opponent Roster, or half the amount of Grid Stalls, whichever is smaller.
Some notes about Registering the AI Opponents for the Session:
- - After Registering for their Session and before the Session Host clicks to Join their Session, the Session Host can select the amount of AI Opponents that should join with them when they click their Join button via a slider next to the Join button. This could be any number from zero to the full AI Opponent Roster! However, keep in mind that AI Opponents fill grid stalls, just like human players, and once they are Registered, that grid stall is filled, and they can not be removed. However, the Session Host can exit their Session and re-join, increasing the number of AI Opponents to register with them before the Race starts.
Sorry, AI Drivers may not have Protests filed against them!

Damage Modeling
The “No Damage” mode has been updated for improved interaction with collisions.
- - This damage mode now allows the simulation to execute full vehicle damage, allowing the physics to perform accurately for more realistic collisions. Then, after the crash has settled and a very short duration, all vehicle damage is immediately repaired. This alleviates impossible physics behaviors that could occur under the previous system which utilized some indestructible and non-pliable objects. These changes should make vehicle collisions more realistic and predictable, even when racing with damage disabled.
- - This system operates when using either the original damage model or the New Damage Model.
A new system message is now displayed when the Simulator is using any damage model other than normal damage.
Fixed a long-standing bug where player wheels would sometimes pass through opponent cars and/or their wheels.
- - This fix should significantly improve the consistency for car-to-car interactions for all cars.

Hickory Motor Speedway
NEW TRACK!
- - A new asphalt oval, Hickory Motor Speedway, is now available!
- - - - Before NASCAR’s biggest names first shone under the bright lights of Charlotte Motor Speedway, many of them found their first successes elsewhere in North Carolina. The city of Hickory plays home to the World’s Most Famous Short Track, Hickory Motor Speedway, a .363-mile asphalt bullring that has welcomed racers and fans through its gates for more than 70 years. From its early days since opening in 1951 as a half-mile dirt oval to the current day, Hickory’s fastest drivers have had what it takes to win at racing’s highest levels. Ralph Earnhardt had five track championships in those early days, while Junior Johnson and Ned Jarrett also scored titles at Hickory early in their Hall of Fame careers. While the track would eventually be reconfigured multiple times before taking its current shape, the quality of names on track remained the same, with legends like Jack Ingram and Harry Gant earning titles of their own later on. For much of its history, Hickory played host to what is now known as the NASCAR Xfinity Series, and it even hosted nearly two decades of NASCAR Cup Series racing before the 1972 schedule shift that consolidated the division. Nowadays, it’s a premier circuit on the NASCAR Advance Auto Parts Weekly Series map, and a crucial part of multiple Super Late Model series’ calendars.

Hungaroring Circuit
NEW TRACK!
- - A new asphalt road course, Hungaroring Circuit, is now available!
- - - - Conceived in the mid-1980s, placed just outside of Budapest, and built in a rapid eight months, the Hungaroring became the host of the first-ever Formula 1 event in eastern Europe in 1986 when it welcomed the inaugural Hungarian Grand Prix. Originally, organizers had wanted a street circuit, similar to Monaco; while a permanent circuit became the eventual choice, the track features a number of tight and challenging corners that make it polarizing among drivers. In its more than 30-year history, the track has crowned two Driver’s World Champions and four Constructor’s World Champions at its events. It’s also the site of numerous firsts, including four first-time F1 winners and the first drivers from both Hungary and Poland to compete in the series. The Hungaroring has also added various sports car, touring car, motorcycle, and open wheel feeder series to its portfolio along the way, with a regular premier touring car event supplementing the schedule for more than a decade.

iRacing Partners With Mercedes-AMG Petronas F1 Team to Build Multiple World-Class Racing Vehicles

iRacing and the Mercedes-AMG Petronas Formula One Team are pleased to announce that the iconic race team will bring multiple vehicles to iRacing in future builds. Headlined first by the Mercedes-AMG F1 W12 E Performance that currently leads the World Constructors’ Championship standings, the partnership is the latest example of a strengthened commitment by iRacing to adding the world’s premier cars and tracks to an already robust simulation experience.

“We couldn’t be more excited to add world-class race cars like the Mercedes-AMG F1 W12 E Performance to iRacing in the near future,” said iRacing executive vice president Steve Myers. “The Mercedes-AMG Petronas F1 Team has been the dominant marque at the highest level of motorsport for quite some time, coming off of seven consecutive championships for its cars and drivers, and bringing their world-class machines to iRacing further establishes our commitment to providing our nearly 200,000 devoted iRacers the world’s most authentic sim racing experience.”

“We have been working closely with iRacing since the start of 2021 to bring the W12 life in iRacing’s virtual environment," said James Vowles, Motorsport Strategy Director, Mercedes-AMG Petronas Formula One Team. “The intent was to create as accurate a representation of W12 as possible from a performance and driving perspective. Throughout the process we have held a unique and close relationship with the developers, which has generated a model we hope everyone enjoys driving as much as our drivers have.”

Work on bringing the Mercedes-AMG Petronas F1 Team vehicles to iRacing has been an extended process. As part of the development work, the team performed extensive testing within iRacing and provided feedback and data to improve iRacing’s overall open-wheel physics model. Many of these adjustments to the physics model have already been deployed to the iRacing user base.

Outfitted once again in a striking black livery, the Mercedes-AMG F1 W12 E Performance kicked off the 2021 season with a dual podium finish in Bahrain, with seven-time and defending World Drivers’ Champion Lewis Hamilton taking the victory. Through the Italian Grand Prix, the car has led teammates Hamilton and Valtteri Bottas to four wins, 18 podiums, four poles, and six fastest laps. The team is currently pursuing its eighth consecutive World Driver’s and Constructor’s Championships with the car.

In addition to the W12, iRacing will work in the coming year to bring the team’s 2022 challenger to the sim as well. The 2022 vehicle is being developed to a revised set of championship regulations. New technical regulations will include the reintroduction of ground effects for the first time since the 1980s, simplified power units, certain standardized components, and larger, 18-inch wheels, among many other changes.

The addition of the pair of Mercedes-AMG F1 Team vehicles comes after iRacing has already launched or announced a host of current Grand Prix venues, including the HockenheimRing, Red Bull Ring, and Hungaroring, in recent months. They join fellow 2021 Grand Prix hosts like Silverstone, Spa-Francorchamps, Monza, Suzuka, and Circuit of the Americas, among others, as tracks that iRacers will be keen to immediately drive upon each car’s release.

Cool as!!!

[norbs]

Duke no longer needs pornhub, that announcement gets his motor running.

[Scottie]

I'm surprised they managed to get the 2022 car in also.

So far the only F1 cars have been old versions to protect Intellectual Property, but hey, Scottie's not complaining!

[nutty]

I assume the 2022 car wont be until a good way into 2022

[nutty]

Saw this on the forum.
https://forums.iracing.com/discussion/9 ... updates/p1

So basically B Class has 40min GT3 sprint, 20min GT3 fixed and the 45min IMSA series which is now LMP2 + GT3.
A Class is now the 1 Hour Le Man style LMP1-2 and GTE and 6 Hour weekly enduro.

I really like racing the GTE car over the GT3 car, but with IMSA removing GTLM next year and the contract iRacing have with them, it makes sense to have that alignment.

I assume that the "European" series in iRacing will stick to GTE for now, but it looks like GT3 cars will replace GTE in 2024.. kinda sees the death of GTE holistically, which I assume means it will follow in iRacing.

IMSA Vehicle Class Updates

In an effort to better replicate the 2022 IMSA vehicle lineup, beginning with Season 1, 2022 (December build) we will be adjusting the car classes included in both the IMSA and IMSA Endurance series.

The new vehicle lineup will include 2 classes; LMP2 and GT3 (GTD). The included vehicles will be as follows:



LMP2:

Dallara P217



GT3:

Audi R8 LMS

BMW M4 GT3

Ferrari 488 GT3 Evo 2020

Lamborghini Huracán GT3 EVO

McLaren MP4-12C GT3

Mercedes-AMG GT3

The 4 GTE cars that are no longer racing in this series can still be raced in the European Sprint and European Endurance Series.

This forces all participants to begin the Race Session with the same tire type with which they performed their Qualifying with. If the participant did not complete Qualifying, they may select any available tire type to begin the Race.
Resolved an issue where deleting a Heat Race configuration for a future scheduled Hosted Session was causing an error when attempting to edit the future Hosted Session.


Hosted AI Racing
Fixed an issue where registering then withdrawing from your own Hosted AI Racing Session would carry-over the AI Opponent amount slider from the session to subsequently Registered sessions.


AI Opponent Rosters
Fixed an issue where adjustments to AI Car Sponsors were not being saved.


Time Attack
A button has been added to the results section to download the Time Attack Results as a .csv file.


Paint Shop
A new sponsor, Force Dynamics, has been added to the Paint Shop.


Weather
Fixed an issue where the Temperature and Humidity icons were swapped.

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

Race Servers
The iRacing race server farm name is now displayed on the Info page on the Session screen, and is also included in the message shown when the "show latency" control is used.


Team Racing
Fixed a rare issue that could occur when the current driver and a team member both tried to pull the current driver from the car at the same time. The two requests could interfere with each other, leading to a stuck vehicle or other unpredictable results.


AI Racing
AI Drivers have improved their skills with the Porsche 911 GT3 Cup (992).
AI Drivers have received additional training entering the pits at Bristol.
AI Drivers have received additional training entering the final pit stall at the Sebring Club layout.


Graphics
The video memory usage slider should now better account for the use of SpeedTree.


Rendering
Sunset specular map lighting on tracks and cars has been adjusted to remove a strange greenish tint that could appear.
Environment specular mapping at very low sun angles has been adjusted slightly.


Lighting
Fixed an issue with a lighting pop at sunrise and sunset at several older tracks, such as Laguna Seca, which haven't yet been upgraded with the newest shaders.


Driver Animations
Pedal animations should now use the raw throttle position from the user instead of the processed signal. This should prevent things like ECU engine cuts and traction control from producing impossible movements from the pedals.
Fixed an issue with excessive foot movements during auto-blips for GT3 cars that have driver gas and brake animations.


Spotter
Fixed a grammar issue in a spotter message.

Dirt Oval Racing
All Dirt Oval Racing vehicles will now never be served meatballs.
- - These vehicles will never receive a meatball flag for sustaining excessive damage while at any track. This change does not make these vehicles immune to damage - they all will still sustain damage as usual. However, a driver can now decide if and when to end their race due to damage.
- - This change affects the following vehicles:
- - - - Dirt Late Model (ALL)
- - - - Dirt Legends Ford '34 Coupe
- - - - Dirt Midget
- - - - Dirt Modified (ALL)
- - - - Dirt Sprint Car (ALL)
- - - - Dirt Sprint Car Non-Winged (ALL)
- - - - Dirt Street Stock
- - - - Dirt UMP Modified


Rendering
The Track Surface Decal (TSD) rendering system has been optimized to greatly reduce the number of DX11 drawPrim() calls required to render scenes. This optimization reduces DX11 CPU-side bottlenecks at every track, some more than others. Depending on the PC hardware and rendering options, it may improve frame rate by as much as 25%. It helps most at road courses, such as Hungaroring Circuit, Circuit de Barcelona Catalunya, and many others.
Fixed an issue where rubber could appear to be laid down heavily on grass.

Brazil’s Stock Car Pro Series Cars Coming to iRacing in 2022

Brazilian Stock cars? Should Reiza be flattered here?

(those are great fun in AMS2 by the way)

iRacing is excited to announce that a fully updated and re-scanned version of Phoenix Raceway will be coming to iRacing for immediate release very soon! This track update will feature brand new environment artwork, updated textures and objects, and a complete re-scan of the track surface fresh from 2021!

New Version of Phoenix Raceway:
This fully updated version of Phoenix Raceway will REPLACE the current version of Phoenix Raceway, which was scanned in 2012. This replacement will cause the older track version to be RETIRED from the iRacing service.
When Phoenix Raceway is retired, it will no longer be accessible for use, nor will Replays at this track be usable after the new version is released.
We suggest if any users have any Replays at the 2012 version of Phoenix Raceway they would like to keep, they should capture video footage of them as soon as possible!
Finally, since this will be a fully updated replacement track, all current owners of the 2012 version of Phoenix Raceway will automatically be granted ownership of the new 2021 version of Phoenix Raceway for free. Members who do not own Phoenix Raceway may purchase it after release.
This post will be updated with an exact release date when we have one available.

[Legacy] Phoenix Raceway – 2008:
This release will have no effect on the [Legacy] Phoenix Raceway – 2008 track. That track will remain available, will remain part of the iRacing Base Content, will remain free for all users, and Replays will continue to work there.
