Project Motor Racing – Update V2.0.0.3 Deployed

Straight4 Studios has released Update V2.0.0.3 for its Project Motor Racing title, primarily focusing on performance, stability, and overall usability.

Update V2.0.0.3 also introduces Multi-Draw Indirect (MDI) on the PC platform, a significant rendering upgrade that improves how the engine handles large, complex scenes, resulting in a more consistent frame rate, better use of modern hardware, and a stronger technical foundation for future multi-view features such as VR and triple-screen support.

The update also contains an updated throttle response model, a new relative timings function for the Digidash, giving players more detailed information about the race position and gaps to opponents. Furthermore, the Porsche 911 Carrera Cup (964) received a reworked handling model and an updated tyre model.

First introduced in Update 2.0, the anti-cheat system, already tested in Ranked Online, has now been expanded to include Factory Driver Challenge, Endurance Hall, and the Ranked Online License Test to help ensure fair and consistent leaderboard results.

Check out the full changelog for all the details.
