PHYSICS

PHYSICS:

- developed new tire damping method increasing compliance and drivability in all situations and all cars, but race cars in particular

- adjusted tire inertia to better match each car's individual tire dimensions helping with more realistic tire lockups and less drastic loss of traction

- improved tire slip ratio calculation leading to more natural behavior particularly on corner exits in locked differential scenarios

- adjusted grip levels for all tires: Higher baseline grip, yet less combined grip leading to more natural, controllable and rewarding car behavior

- adjusted thermal behavior for tires alongside adjusted rolling resistance

- adjusted tyre rolling resistance to achieve more realistic top speeds

- implemented new drive train wobble method respecting non linear stiffness

- adjusted tire wear across all compounds (generally, the more performance oriented a tire is, the faster tire wear will noticably impact laptime)

- sanitized and unified tire and controller library, solving potential inconsistencies in tire model across cars

- improved consistency in available compound range for early-modern cars:

Removed pseudo-vintage tyres for 90s-00s models, they are now fitted with a range of modern tyres suiting their performance, vintage reserved for crossply tyres

- improved hybrid powertrains

- implemented and unified KERS/ERS behaviour

- improved Dual Clutch Transmission behavior to be more seamless

- implemented electronic brake bias (dubbed as EBB or Brake Migration)

- revision of battery features and data entry specifications

- improved physics model for cars with solid axles

- made several car systems available for in-cockpit adjustment (among others: turbo, dampers, differentials)

- Ferrari 296 GTB: numerous fixes and adjustments to suspension, drivetrain, downforce, airbrake and dedicated performance modes with more realistic ERS deployment

Recommended driving.

- implemented soft lock feature for steering wheels

- created multiple physics events to allow for more nuanced car audio

- fixed a potential crash scenario caused by collisions

- various steer ratio adjustments on a number of existing car content

- created more true-to-life vintage compound for the Alfa GTA Sprint

Recommended driving.

- various adjustments to engines, turbos, drag and downforce across cars to better match real life acceleration, top and corner speeds

- various adjustments and fixes to car default setups and differentials

- fixed F2004 rear wing not responding to changes in setup and modified setup limits for the car

- added stiffer springs for the Porsche Cayman GT4 CS MR and Porsche 911 GT3 Cup

- adjusted torque curve for the Porsche Cayman GT4 CS MR

- fixed Audi RS 6 bump stops to prevent tyre hitting and clipping through the bodywork

- fixed Dallara louvers (front fender air vents) downforce impact

- corrected Mazda MX5 Cup weight and differential

- corrected differential of the Caterham Academy

- improved various cars' rpm limiters to behave more realistically

- corrected gear ratios for the Ferrari 296 GTB

- corrected gear ratios for the Chevrolet Camaro ZL1 and 1LE variant

- corrected Mazda MX5 Cup Sadev sequential gear ratios

- corrected Alpine A110 and VW Golf GTI Clubsport gear ratios

- updated operating aero and ride height ranges on the BMW M4 GT3 Evo and enabled bump stop adjustments

Recommended driving.

- updated operating aero and ride height ranges on Lamborghini ST EVO II

- updated BMW M2 CS Racing setup limits according to BMW specifications, updated spring ratios

- updated and unified all car names in setup folder

- car colliders can now be angled when necessary to represent built-in rake of cars

- reduced clutch sensitivity

- fixed unwanted vibration on torque vectoring differentials

- sanitized and updated TC & ABS behaviour on all cars

Fixed engine-crippling behaviour of earlier iterations of traction control, so higher levels might work better on some cars, and lower levels allow for more playful driving. The new Porsche Cayman GT4 RS is a good showcase.
