From the DRM PDF:
Changelog V1.3
ALL CARS
PHYSICS: corrections up and downshift algorithm to force the driver for more precisely gear changes
PHYSICS: clutch becomes slippy when you incorrectly shift gears during acceleration in the high
rpm range
PHYSICS: reworked rain tires
PHYSICS: AI will not choose the rain tire in the practice/race sessions anymore
PHYSICS: some improvements at the setup menu ( range, step, min and max values )
PHYSICS: unique wear curve for the rain tire
PHYSICS: added camber lut table for all cars ( strut, double wishbone, life axle )
PHYSICS: add the parameter [VIRTUAL_KM] to all tyres.ini for calculate the accurate wear
Now you'll have tyres on the more loaded side of the car wear differently than the one on
the inside
PHYSICS: increase tire grip for new tires to 98% ( before 96.5), 100% grip at [VIRTUAL_KM]=1
PHYSICS: more stable tire at higher temperatures
PHYSICS: add the parameter [EXPLOSION] to all tyres.ini. At 180 Celsius, the tyres will blow
PHYSICS: corrections at the rim radius and tire width
PHYSICS: optimizing the collision model
PHYSICS: corrections of the LINEAR_STEER_ROD_RATIO
GRAPHICS: added smoke exhaust for each car ( when using the shader patch )
GRAPHICS: decrease headlight brightness in cockpit view for night session
GRAPHICS: reduced the OnBoard_Exposure to 16
GRAPHICS: same value for the exposure value for the dash cam
