Project Motor Racing update “overhauls” GT3 and GT4 dynamics amongst long list of changes

The third major post-release update for Project Motor Racing is now live, following team layoffs and a re-focusing of the development plan.

Chief among the changes is what’s being touted as “refined handling” for GT4, GTE, Porsche Cup, GT and NGT car classes, following a similar change for GT3 cars last month.

Additionally, a “full tyre overhaul” for the GT3 and GT4 categories has been implemented, and thank goodness, downshifts are said to be “smoother” – a real bugbear of ours for certain vehicles.

In combination with the vehicle dynamic changes, “overall force feedback feel” for those with a racing wheel is said to be “improved”, with particular attention given to those with a Fanatec, Thrustmaster or Logitech device. FFB menus are now said to be ‘cleaner’.

While some cars can sound deep and throaty, others have been wide of the mark, in particular the naturally aspirated Aston Martin Valkyrie LMH. This now has a different engine sound mix.

Among the litany of unrefined elements within Project Motor Racing is the visual performance, both detail and smoothness. This patch is stating some improvements here too, with different tree textures, colour grading (hopefully to Sebring), and, quote, “lots of fixes to floating objects, LODs, lighting, shading and environment detail across many tracks.”

The full changelog is listed below, with further updates expected imminently.

Project Motor Racing Update 1.5.0.2 patch notes

UI & Quality of Life

• Cleaner, clearer steering and FFB calibration screens.

Vehicle Handling & Physics

Global improvements

We’ve refined handling across many classes, including:

• Full tyre overhaul on GT3 & GT4
• GT4, GTE, Porsche Cup, GT/NGT.
• Auto-shift downshifts are smoother and avoid unintentional gear-stall moments.
• Steering angle limits adjusted to prevent tyres clipping bodywork.

Vehicle-specific updates

• Mazda MX-5 Cup: fixed liveries, visuals, torque/inertia.
• Porsche Carrera Cup: better wiper vibration.
• Audi R8 LMP900: reduced cockpit shake.
• Sauber C9: gauge & display fixes.
• Acura ARX-06 / Alpine A424: camera and content cleanup.
• Multiple GT3/GT4 cars: handling refinements.
• BMW M4 GT4: fixed rear brake disc wobble.
• Valkyrie: updated engine sound mix.

Graphics & Visual Improvements

• Brighter, clearer cockpit lighting and exposure.
• Better colour grading and tone mapping.
• Fixed over-bright car reflections in pre-race and replay cameras.
• Independent windscreen cleaning (pit stops now clean both car and replay views).
• Updated trackside trees with improved textures and colour variety.
• Lots of fixes to floating objects, LODs, lighting, shading, and environment detail across many tracks.

Track Fixes & Enhancements

Track updates across Nürburgring, Spa, Zolder, Mosport, São Paulo, Brianza, Lime Rock, Derby National, Spielberg, and more:

• Crowd placement & optimisation
• Collision fixes
• Lighting and shadows
• Grass colour matching
• Replay cameras
• Cleaner geometry and better performance

Online & Systems

• Faster leaderboard and stats loading.
• Improved stability and reduced log spam on the master server.
• Fixes for competitive lobby exit bugs.
• Resolved an issue that could freeze the game at the end of a race.

Gameplay & AI

• Default vehicle setups now autoload when present and appear in setup list.
• Active setup auto-saves across sessions.
• Debug keys added for moving between AI opponents for modding purposes.
• Adjustments made to prevent shortcuts/advantages at Derby National.

Miscellaneous

• Added safety measures to prevent certain rare crashes.
