iRACING:
--------------------------------------------------------------

Static Assets and Series Standings
Changes have been made to resolve sporadic failures when loading Standings, Time Attack schedules, some layers of tracks maps on the Classic Membersite and in iRacing, as well as some schedule data from iRacing Live. These errors were occurring due to a misconfiguration on the content delivery network (CDN), allowing this data to be cached without the necessary headers, causing it to fail.


My Cars
Fixed an issue where clicking on the Hosted Sessions option within the Find Sessions section would cause an error.


SIMULATION:
--------------------------------------------------------------

New Damage Model
Fixed a damage data processing issue that could cause cars to become outer space vehicles.
- - This data processing issue was most easily reproduced by applying a new setup that altered the spring dampers and then crashing the car so the wheels would break.


Spotter
The Ari Cejas Spanish Spotter Pack has been updated, with a full rewrite!
- - Many thanks to Ari for the hard work!
Updated the Portuguese Spotter Pack.


Replays
Fixed an issue that would cause only a portion of a Replay to be saved out at shutdown if you had enabled the “Save Replay at Shutdown” option and had previously clippled a portion of the Replay out prior to quitting.


CARS:
--------------------------------------------------------------

NASCAR Cup Series Next Gen Cars
Fixed an issue where these cars’ black boxes were receiving incorrect brake bias values.
Fixed an issue where scrape damage was appearing on the interface model for these cars.


NASCAR Truck Trucks
Updated the vehicle textures for distant camera views.


ARCA Menards Chevrolet Impala / Gen 4 Cup
(ARCA Menards Chevrolet Impala) - Engine parameters have been reverted.
(Gen 4 Cup) - NEW CAR!
- - The Gen 4 Cup is now available for official purchase and use!
- - - - The NASCAR Cup Series Gen 4 Chevrolet is based on the fourth generation NASCAR Cup Series car that ran through 2007, when the Car of Tomorrow took over. Gen 4 cars made their debut in the early 1990s and were used throughout NASCAR's boom of the late 1990s and early 2000s, leading Jeff Gordon to all four of his championships and both Dale Earnhardt and Jimmie Johnson to some of their seven - Earnhardt to his last in 1994, and Johnson to his first in 2006. iRacing's Gen 4 car is a higher-horsepower version of the same car used in the ARCA Menards Series, kicking up the 358-cubic inch V8 engine to 725 horsepower. The extra power makes for a more challenging driving experience, and a throwback for those who long for the days of one of NASCAR's classic eras. It's the generation where names like Wallace, Labonte, Jarrett, Martin, and Stewart did battle - and now, at long last, this is your chance to relive it.
- - All Members who owned the ARCA Menards Chevrolet Impala now have access to this vehicle.
A new Damage Model tuning update has been completed, including lowering break limits for the hood and trunk mounts.


Audi R8 LMS GT3
Fixed an issue where scrape damage was appearing on the interface model for this car.

===========================================
2023 Season 1 Patch 4 Release Notes [2023.02.06.02]

This Patch includes a variety of updates and fixes for the 2023 Season 1 Release!


iRACING UI:
--------------------------------------------------------------
Guided Tours
The bowtie icon has been replaced with an “i” icon. Farewell, Jeeves!

Leagues
We have added an input box for a new League Season option: “No Drops on or After Week X”. This allows the user to specify that race weeks cannot be dropped after a given week number. This feature is only enabled if the number or drop weeks is not 0.

Results & Stats
The iRacing UI now allows for viewing Standings by All Cars, by Car Class, by Car, and by Car in Car Class.

Paint Shop
Slightly reduced overexposure for bright colors.


SIMULATOR:
--------------------------------------------------------------
Graphics
The SpeedTree self-shadow option is now disabled by default for all graphics performance classes. Previously, it had been enabled in all graphics performance classes, but it requires two extra renders of the trees and may have contributed to stuttering or a general performance hit.

Visual Effects
Fixed an issue where brake rotor glow was not appearing correctly on the following cars:
- - Aston Martin Vantage GT4
- - Audi RS 3 LMS
- - BMW M4 GT4
- - BMW M Hybrid V8

Texture mapping on the front fenders has been updated, which fixes issues with damage decals and camera draw distances.

NASCAR Truck Ford F150
Fixed an issue with duplicate contingency decals on the nose.


TRACKS:
--------------------------------------------------------------
Los Angeles Memorial Coliseum
Starting grid positions have been moved away from the wall slightly.

Long Beach Street Racing Course
Adjusted the location of the short parade lap grid to give the rear of the field time to get rolling before the green flag is given.

Wild West
Fixed an issue where cars that missed the start would be released immediately and would come out of the pits way ahead of the pack. Now, Race Control properly holds these cars for about 20 seconds so they come out just behind the pack as expected.

=============================================
2023 Season 1 Patch 3 Hotfix 2 Release Notes [2023.02.01.02]

This Hotfix includes a needed fix for the 2023 Season 1 Patch 3 Release.


SIMULATION:
--------------------------------------------------------------
Tire Model
Fixed an issue for some cars where tire rubber was becoming unrealistically extra conditioned when driving over curbs and rumble strips.

Surface Model
Soft surface model properties for gravel have been updated.

New Damage Model
A system-wide adjustment has been made for how bodies that connect and retain contact with each other over time behave. This change is designed to reduce the likelihood and severity of objects snagging on one another.
- - Objects that retain contact with each other must be allowed a degree of lateral displacement, provided they can overcome the forces of friction provided by their surfaces, the angle of movement, and the force of the movement. Too much displacement can cause snagging. To avoid snagging, we have limited the amount of displacement allowed relative to the axis of contact.
Physics properties for a variety of wall objects have been adjusted to prevent snagging and catching behaviors, as well as reduce the likelihood of a vehicle becoming stuck bisecting the wall. These adjustments should also create more uniform damage from impacts based on the wall type. The wall types affected include: concrete, chain link fences, ARMCO barriers, and tire walls.

Replays
Fixed an issue where users’ screens would serve a 10 second penalty in a dark void after loading a replay that included the maximum number of car types in the session.


CARS:
--------------------------------------------------------------
GT3 Cars
A New Damage Model tuning update has been completed for these cars to avoid excessive scraping from curb impacts.

NASCAR Cup Series Next Gen Toyota Camry
Texture mapping on the front fenders has been updated. This fixes some UV warping from the 2023 Season update, and fixes issues with damage decals and camera draw distances.


TRACKS:
--------------------------------------------------------------
Daytona International Speedway
(Road Course) - Slowdown penalties have been added to the banked apron, and cones have been adjusted to show where it is safe to use the apron again.
