ZoomProject Motor Racing/GT Revival/GTR RevivalAlle Bilder3 Tage nach dem Release von Project Motor Racing, zu dem Straight4 Studios bereits einen Day-1-Patch bereitstellte und sich in der Folge unterschiedlich stark ausgeprägter Probleme genötigt sah über die weiteren geplanten Schritte zu informieren, hat das Entwicklerteam am Freitag, 28. November 2025 die Version 1.5.0.1 bereitgestellt.
Wie sich dem durchaus umfangreichen Änderungsprotokoll entnehmen lässt, wird damit in verschiedenen Bereichen nachgebessert. Vom Online- und Multiplayerbereich über die allgemeine Programmstabilität, Gameplay und KI bis zu Fahrzeugen und Strecken reichen die Maßnahmen, mit denen das Spielerlebnis stabilisiert und die angesichts der Probleme zum Launch nachvollziehbare Kritik eingedämmt und die Stimmung allgemein verbessert werden soll.
Auch erste Verbesserungen und Optimierungen die das Fahrverhalten der GT3- und LMDh-Rennwagen betreffen sind neben Dutzenden von Fehlerbehebungen in den zweiten Patch eingeflossen. Darüber hinaus gibt es eine zusätzliche Unterstützung von Lenkrädern, Pedalen und Schalthebeln.
Project Motor Racing - Patch Notes – Version 1.5.0.1:
Online and Multiplayer
-Added a new warning message when the game client is outdated and cannot play online.
-Fixed a missing callback that caused version-mismatch connection failures.

-Improved shutdown handling of audio graphs when network users disconnect.
-Improved server performance.
-Fixed a crash caused by processing the lobby list twice.
-Fixed missing text in the player reporting dialog.
-Fixed a crash when finishing a Social Race.
Stability and Systems
-Added protection in audio code to prevent rare invalid value ("NaN") errors.
-Addressed fast-math divergence between platforms to improve simulation consistency.
-Fixed incorrect vehicles showing up in License Test after starting an Endurance race.
-Added additional null-pointer protection and increased memory headroom for True-Track presets to resolve rare crashes.
