Update der GT3-Physik

Worauf viele User lange gewartet haben, ist ein grundlegender Refresh der GT3-Reifen und der Aerodynamik. Einige Änderungen betreffen dabei folgende Punkte:

Die Reifenphysik für Trocken- und Regenreifen wurde überarbeitet. Laut iRacing wurden hier grundlegende Änderungen durchgeführt, um ein realistischeres Fahrgefühl zu ermöglichen. Dazu gehören auch neue Reifenwärmer, sodass man mit deutlich kälteren Reifen aus der Box fahren wird.
Es gab auch Änderungen bei der Traktionskontrolle. Diese soll nun realistischer eingreifen.
Es gab nicht weiter spezifizierte Änderungen bei den aerodynamischen Parametern.
Zudem wurde die Bestimmung des tiefsten Punkts des Autos geändert. Dies hat direkten Einfluss auf die Legalität von Setups.
Es gibt BOP-Änderungen sowie ein neues Balancing beim Spritverbrauch.
Nach dem Update sind alle alten Setups unbrauchbar.

360Hz, MOZA LFE und Fanatec FullForce-Support

Ein Punkt, auf den viele User aus der Community lange gewartet haben, ist die Unterstützung von 360-Hz-Wheel-Bases. Mit dem neuesten Update kommen gleich drei neue Hersteller mit ihrem Angebot dazu.

MOZA (The MOZA API has been updated, which adds support for 360 Hz force feedback.)
VRS (The VRS API has been updated, which adds support for 360 Hz force feedback.)
Asetek (The Asetek API has been updated, which adds support for 360 Hz force feedback.)

Zusätzlich gibt es jetzt einen neuen Reiter mit dem Namen Wheel LFE bei den Einstellungen. Hierüber kann man mit einer kompatiblen Base Effekte wiedergeben, die außerhalb des regulären Bereiches liegen. Mit dem Update werden MOZA Bases unterstützt:

The Moza API has been updated, which adds support for Moza Low Frequency Effects (LFE) Wheel haptic effects and 360 Hz mode.
- The Wheel LFE allows you to send tactile vibrations to the wheel like engine vibrations, that would normally be too high of a frequency to send across the normal DirectInput Force Feedback api. You can tune these effects in the [TrueForce] section of our app.ini file. You can turn off the Moza API via the app.ini switch [Force Feedback] loadMozaAPI=0.

Ebenfalls Teil des neuen iRacing-Updates ist die FullForce-Unterstützung für kompatible Wheel Bases von Fanatec. Hierzu wird der aktuelle Beta-Treiber benötigt.

Content-Update: Drei neue Fahrzeuge, eine neue Strecke

Als Teil des neuen Updates haben User die Möglichkeit drei neue Fahrzeuge sowie eine neue Strecke zu kaufen:

Fahrzeuge
- Ferrari 296 Challenge
- Gen 4 Chevrolet Monte Carlo – 2003
- Gen 4 Ford Taurus – 2003
Strecke
- Shell V-Power Motorsport Park at The Bend – GT Circuit

Changelog

Nachfolgend findet ihr den offiziellen Changelog von IRacing, aufgeteilt in die vier Kategorien iRacing, Simulation, Cars und Tracks.

iRacing

General

Clubs have been replaced by country flags in iRacing.
Users can select a country flag to display alongside their name on Profile, Stats, and Results pages.
The selected flag can be changed at any time via the Profile page.

AI Racing

Adaptive AI is now available for Hosted Sessions.
Hosted Session creators can select Adaptive AI as the AI Type during setup, visible to those joining.
Challenge Level is locked in Hosted Sessions, with AI adapting difficulty based on the overall player field’s performance, not just the Host driver.
Adaptive AI for multi-class Sessions is not yet optimized, as AI Drivers are still training to adapt to varied fields. Improvements are expected soon.
Adaptive AI is now available for AI Seasons, allowing selection of an Adaptive AI Challenge rating, adjustable between events.
Nine new AI Seasons have been added: IMSA, IMSA Michelin Pilot Challenge, GT3, GT4, Production Car Challenge, NASCAR Cup, NASCAR Xfinity, NASCAR Truck, and ARCA.
