Update 2.0.0.3 is now live for Project Motor Racing, bringing a wide range of improvements focused on performance, stability, and overall usability.
Headlining this update is the introduction of Multi-Draw Indirect (MDI) on the PC platform, a significant rendering upgrade that improves how the engine handles large complex scenes. Alongside that comes further expansion of the throttle response model, a new relative timings function for the Digidash, and a reworked handling for the Porsche 911 Carrera Cup (964).
Expanding on the existing Digidash tool, a new relative timings function has been added, giving players more detailed information race position and gaps to opponents.
Multi-Draw Indirect (MDI) is a major step forward in how the engine renders large, complex scenes. By moving draw call generation and visibility decisions onto the GPU, CPU overhead has been significantly reduced, allowing the renderer to scale more efficiently with scene complexity.
This enables the game to handle far more objects on screen while improving stability and overall CPU performance.
Alongside this, culling, batching, and render pass organisation have been refined to ensure only the work necessary for each frame is executed. The result is 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.
First introduced in Update 2.0, the anti-cheat system has already been tested in Ranked Online. With Update 2.0.0.3, it has now been expanded into Factory Driver Challenge, Endurance Hall, and the Ranked Online License Test to help ensure fair and consistent leaderboard results.
Building on the foundation introduced in Update 2.0, and later expanded in Update 2.0.0.2, more cars now benefit from the updated throttle response model.
