Bsimracing Sim Racing Resources and News for the racing enthousiast.
Straight4 Studios has deployed Update V1.6.0.0 for its Project Motor Racing title.
Patch 1.6.0.0 brings multiple stability and performance improvements. The focus is on improving driving behaviour for the LMDh class based on community feedback. With this update, the default brake bias has been shifted closer to a true 50/50 split, alongside changes to rear brake sizing, to better reflect real-world data. This means older setups that were built around the previous bias may now feel unstable under braking, particularly into heavy braking zones or trail braking situations.
Players using their own setups in LMDh, GT3, GT4, and the 992 Cup cars will want to revisit their brake balance settings. Additionally, the LMDh class has received a substantial round of physics and drivability improvements aimed at making these cars more predictable, rewarding, and realistic across a wide range of conditions.
Other noteworthy improvements in this update include various improvements to the online components that provide a more stable experience. Along with the weather system and time-of-day, now being enabled in Career Mode. Meaning that the start times and weather conditions will be different each time.
Check out the full changelog for all the details.
Changelog V1.5.0.5:
Vehicles
- Fixed an issue affecting certain cars that would turn driving assists off despite them being on.
- Improved windscreen reflections and materials, along with cockpit displays and gauges across multiple cars.
- Additionally, the Porsche 992 GT3R has received improved cockpit vibrations.
Handling & Physics
- Improved collision handling and restitution.
- Fixed collision cleanup when vehicles are teleported.
- Improved transmission driveline, gear handling, ignition stability, and brake temperature issues.
- General physics cleanup and refactoring for stability and performance.
LMDh
- New tyre revisions with improved grip and predictability in cold temperatures.
- Changes to the engine modelling for more realistic revving and inertia.
- Upshift/downshift tuning to go along with the previously mentioned change.
- Tuned brake balance and ABS settings.
- Updated tyres for improved overall handling.
GT3, GT4 & 992 Cup
- Default Brake Bias changed to be more towards 50% with a change to the rear brake sizes. User-created setups should be revised for this change.
Penalty System
- Improved track limit detection margins and accuracy.
- Fixed incorrect penalties on Nurburgring Nordschleife and Lexington.
- Added safer detection of drivable surfaces outside track limits.
Online & Multiplayer

- Vehicle damage has been enabled for Ranked Online mode.
- Further improvements were made to the Ranked Online scoring system to prevent exploits.
- Fixed crashes related to invalid driver profiles and multiplayer menus.
- Added safeguards to ensure grid positions are correct.
- Fixed a potential soft-lock issue that could occur when selecting events during leaderboard updates.
- Improved maintenance mode handling and network stability.
- Fixed an issue where the racing line could stop updating in online races when a player in the lobby became unready.
Career Mode
- Improved validation for missing DLC, mods, and invalid configurations.
- Championships now only populate with owned tracks and valid grid sizes.
- Weather seasons now appear throughout Career Mode events.
- Weather conditions enabled giving a chance of wet weather conditions.

AI Opponents
- Improved braking logic, throttle response, and understeer/oversteer handling.
- Enhanced AI predictions using track incline, tilt, and wet-line speeds.
- Improved pit stop logic and pit exit behaviour.
- Added slip protection and safer re-joining behaviour after leaving the track.
- Fixed multiple issues related to AI behaviour, causing system crashes.
- Refined AI performance for closer, more consistent racing.
- Adjusted AI tyre wear to better match player performance.
Tracks & Environment
- Added and refined ground collision materials to better support the penalty system across multiple circuits.
- Improved tree LODs, alpha clipping, and billboard optimisation.

- Fixed “micro gaps” for ground surfaces across multiple circuits.
Rendering & Visuals
- Fixed shadow LOD inconsistencies.
- Improved exposure handling, including cockpit exposure masking.
- Fixed rear-view virtual mirror issues on consoles.
- Improved reflection quality and anti-aliasing in mirrors.
