iRacing: 2025 Season 2 Patch 3 und Patch 2 bringen Verbesserungen und neues Feature

iRacing stellt f�r das 2025 Season 2-Build eine Reihe von �berarbeitungen bereit mit denen das Online-Racing weiter verbessert wird.

Zum Ende des Monats M�rz und Anfang April hat das iRacing-Entwicklerteam weitere Verbesserungen an der Online-Rennsimulation vorgenommen. F�r das 2025 Season 2-Build wurden am 27.03.2025 beziehungsweise 03.04.2025 der Patch 2 respektive Patch 3 ver�ffentlicht.

W�hrend die Updates �berwiegend Verbesserungen und Fehlerkorrekturen in verschiedenen Bereichen enthalten, wird mit Patch 3 auch Adaptive AI Racing in Single AI Sessions als neues Feature aktiviert. Wie gewohnt geben die �nderungsprotokolle im Detail Auskunft �ber die jeweiligen mit den Updates verbundenen �berarbeitungen.

2025 Season 2 Patch 3 Release Notes [2024.04.02.02]
Simulation
AI Racing
-Adaptive AI is now available for Single AI Sessions!
--Adaptive AI is an all new system that provides each iRacer an AI Racing experience that's tuned to their individual preferences and desired level of challenge. -Rather than tuning difficulty percentages, with Adaptive AI users choose whether they are looking for a Low, Medium, or High level of challenge. This experience is dynamic and tuned to each iRacer, so one racer's Low might be another racer's Medium. While Adaptive AI is built for iRacers of all abilities, it does have a sweet spot and it's possible that some of our fastest racers might exceed the pace that the system can provide. As with all iRacing systems, Adaptive AI will continue to evolve and improve as we collect and incorporate iRacer feedback.
--Adaptive AI will make its debut in Single Race, with a follow-up planned for Hosted iRacing and AI Seasons at a later date.
-AI Drivers have improved their racing lines at USA International Speedway.
-AI Drivers have improved their racing skills with the NASCAR Truck Series Class Trucks.

Physics
-The physics processing for collisions involving opponent vehicles has been updated for improved accuracy.
--Opponent cars now automatically update their physics processing frequency to a much higher rate any time they detect they are in close proximity to any object, or whenever a collision occurs.
----This alleviates an issue where opponent vehicles could sometimes appear to snag on walls, climb up objects, or trigger other visual oddities.
--Torque scaling applied during impacts to wheels has also been adjusted. Opponent vehicles now behave much more realistically when striking walls with their wheels.

Dynamic Track Model
-Updated the appearance of dynamic track debris within the space tangential to the track surface.
-Fixed an issue with normal mapping of track debris, making their visible bumpiness more correct.

Graphics
-Lighting exposure intensity for when the sun is within 15 degrees of the horizon has been reduced.
-Improved the brightness of pit entry/exit lights and caution lights, especially at sunset.
-Improved brightness in foggy, rainy, and overcast conditions.
-The lighting gradient at the horizon line has been improved.
-Improved the appearance of fog over terrain surfaces and in mirrors.
-Improved MSAA processing for foggy conditions.

Spotter/Crew Chief
-For Autofuel, fixed an issue where fuel usage data could sometimes become invalid between sessions. Additionally, if invalid fuel data leaks into the autofuel system, it will now be discarded and the system will be reset instead of corrupting future data.
-Some Foreign Language Spotter Packs have been updated.

User Interface
-Fixed an issue where the training Race Line was always white, instead of color-coded to indicate braking and acceleration zones.

Cars
ARCA 2025 Series
-For custom paints, a headlight has been moved to the decal layer, so custom paints may once again stamp numbers over them.
-For the damage model, friction parameters have been increased on the tire and rim sidewalls to prevent any benefits from wall-riding.

BMW M2 CSR
-Fixed an error where the left-front tire change always required an additional 5 seconds. This tire changer has been re-assigned to a new job more befitting his talents.

NASCAR Cup Series Chevrolet Camaro ZL1
-Fixed an issue where the shadow of this car was incorrect.

Tracks
-Circuit des 24 Heures du Mans
-Fixed an issue where some sausage curbs had a tasteless inverted texture.

Darlington Raceway
-Some advertisements have been updated.

Oulton Park Circuit
-Fixed the super secret off-track error at the Turn 3 exit.
-Sebring International Raceway
-Removed a troublesome tire bundle from Turn 3.

2025 Season 2 Patch 2 Release Notes [2024.03.25.02]
Simulation
Dynamic Track Model
-Fixed an issue where track debris was very difficult to see at a distance.
-Fixed an issue where the visual effects for track debris were not displaying an appropriate amount - it would appear as though less debris was present than actually was.
-Updated the appearance of track debris based on the viewing camera angle.
-Track debris rubber marbles have been adjusted for improved visibility.
-Improved the visuals for gravel debris particles.

Graphics
-Solar flare intensity has been reduced. We still do not recommend staring into the sun.
-Updated solar flare coloration and brightness.
-Improved specular map behaviors for some older environment objects.
-Reduced the reflectivity for a variety of smooth and shiny objects.
-Improved the lighting exposure during rainy and foggy conditions.
-The sharp MSAA filtering process has been expedited and improved - artifacts should no longer occur at extreme intensities.
-Reduced the specular lighting intensity for dirt and oval track surfaces.
-Reduced flickering that could occur in very bright HDR pixels while using MSAA.
-Fixed the lighting on rain particles and rain sprays in all conditions, but mostly at night.
-Several trees that were extra bright at Sebring night and some other tracks have been improved.
-Fixed an issue where some tire skid marks without nearby lighting were eerily glowing in the dark.
-Fixed an issue where tire marks made at night during wet weather would appear extra-bright.
-Fixed an issue where vehicle headlights were not illuminating tire smoke correctly.

Spotter/Crew Chief
-Some spotter packs have been updated.

Autofuel
-Fixed an issue where the Spotter could incorrectly inform you that you had insufficient fuel at the start of an event.

Cars
ARCA 2025 Series
-Various manufacturer art elements are now locked in the paint templates for these cars.
