Straight4 Studios released update 1.6.0.0 for Project Motor Racing today bringing some meaningful changes that setup builders will notice right away. The default brake bias now sits much closer to a true 50/50 split with adjustments to rear brake sizing to better line up with real world data. Because of that shift, older tunes created around the previous balance might feel a little squirmy under braking, especially in heavy zones or when trail braking into a corner.
Anyone running custom setups in LMDh, GT3, GT4 and the 992 Cup cars will want to jump back into the garage and make a few tweaks. The LMDh class also received a big round of physics and drivability work aimed at making the cars feel more predictable and more rewarding to push in a variety of situations.
Beyond the car changes, players should run into a smoother experience online. Career Mode now features active weather and time-of-day support too, so start times and conditions can be different each time you load into a race. Check out the full patch notes below.
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.
- 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 on 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
- Fixed an issue that could cause players to experience a black screen when another player quitted the lobby and fall through the environment.
- Vehicle damage has been enabled for Ranked Online mode.
- Further improvements 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.
- Start times have been reviewed to give more time-of-day variety including night-time.
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, 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 texture issues, clipping and LOD (level of detail) distance setting, and colour saturation on walls, kerbs, and terrain across multiple circuits.
- Fixed “micro gaps” for ground surfaces across multiple circuits.
- 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.
- Fixed fog fade issues, black sky cases, and near-fade artefacts.
- Ensured atmosphere quality can no longer be disabled.
- Fixed intermittent overlay rendering and outline issues.
- Improved mini-map behaviour and performance.
- Enabled input display graphic on the bottom left of the HUD when using a controller.
