CARS
Fixed go-pro cameras in replays clipping with bodywork on ultra-wide resolutions in Hyundai i20
Fixed gameplay cameras clipping with damaged bodywork in Citroen Xsara WRC
Fixed exposure of “Between Heads” and Driver/Co-Driver go-pro cameras in replays for all cars
Reduced direction-based ambient occlusion on cars
Updated LCD on Lancia Delta
Updated license plates on Skoda Fabia
Added competition logos on all cars
Made the back face of window stickers less saturated (simulated the paper backing)
Many minor bug fixes across all cars
INPUT
Implemented Fanatec FullForce and Logitech TrueForce, with new in-game FFB parameter to be tuned by users
Improved generic devices compatibility. This enables more devices to work as expected.
PHYSICS
Added angular damping to small movable objects to prevent unrealistic spinning
Added Peugeot 306 Maxi Kit Car and Subaru Impreza S3 Group A
With the Peugeot 306, it was made available for the first time the adjustment of brake bias through a pressure limiter valve (similarly to tandem master cylinders cars) instead of a balance bar. This, despite the car having a dual master cylinder setup. This allows the driver to reduce rear brake pressure without increasing the front one.
Further tires tuning for all surfaces, in particular:
The way wet conditions and snow affect tire forces has been modified; they no longer reduce cornering stiffness, and the S-shaped curve is effectively cut off when grip is saturated.
In the case of snow, an additional experimental deformation component has been added to the slip angle, which increases the more suitable a tire is for snow. This simulates the tire actually gripping the underlying surface.
These changes make the transition between grip and no grip more immediate and noticeable on both wet and snowy surfaces, improving the car’s responsiveness in the wet and its controllability on snow.
The parameters related to the tire’s dynamic masses and damping have been fine-tuned for more consistent force delivery.
The ability to grip on snow has been added to gravel tires, making them suitable for driving on snowy gravel roads.
The parameters of the tire’s S-shaped curve have been adjusted based on test data.
The load sensitivity parameters of some tires have been refined based on results from field tests.
Revised aerodynamic tuning for both drag and lift forces
Revised some vehicles setups and presets to improve handling or to make it more adequate to latest tires changes.
AUDIO
Impreza Engine/Exhaust implemented. The sound will improve further in the future – our audio designer is an Impreza owner and wants to make it perfect!
306 Maxi Engine/Exhaust implemented.
Skoda exhaust after-fire implemented.
Rally2 turbo added to Skoda
Improved gravel skid feedback.
Improved 3rd person spatialization for replays especially approaching from a distance.
Improved 3rd person spatialization for forced induction.
Improved 3rd person spatialization for rear engine vehicles.
Fix for turbo BOV sounds cutting off too early based on the drop in turbo pressure.
Fix for too much “hill” reverberation coming through the cabin view.
Fix for various sounds cutting out randomly.
GAMEPLAY & UI
Updated pacenotes for Monte Carlo Bollene
Updated pacenotes for Monte Carlo Sisteron
Fixed incorrect pacenote call on Wales Hafren North 3/6
Fixed stop marshals at Monte-Carlo Bollene 7/8 and Monte-Carlo Sisteron 6/6 not guiding player to stop point
Fixed some incorrect respawn collisions around crowd on Monte-Carlo Bollene walls
Fix an issue resulting in the automatic tire allocation on rally weekends to give an odd number of total tires and single compounds.
Fix an issue preventing the automatic tire allocation to give the correct number of multiple compounds tires. This allows for more tire choices during rally weekends, even while using the automatic selection.
Added Apply button in Video options
Fixed minor text and translations issues
ONLINE
Player session now correctly sets the client version
Added the Partners functionality
Leaderboards: added a dedicated endpoint for fetching leaderboards as Partner
