This is a hotfix to the latest update correcting the more pressing bugs intrroduced with it and also bringing a few further fixes and improvements to AMS2.
Some performance issues with AMD hardware have been addressed as have issues with flickering foliage and other minor visual oddities introduced with the latest shader updates; the game should also again launch fine from third party apps.
V1.6.5.1 CHANGELOG
GENERAL
Reduced the painted track detail offset to reduce overlap with vehicle tyres while still avoiding Z-fighting on large tracks
Reverted WIP development to aero flaps causing some existing cars equipped with DRS to malfunction
Reverted the damp track racing line visual changes which created some edge cases that caused the track to look too reflective
Fixed Shader causing flickering on Radeon GPUs.
Relaxed threshold for track limit violations in previous lap to invalidate the next lap in all non-TT game modes
UI & HUD
Fixed Test Day keyboard/controller menu navigation layout
Added graphics option to enable/disable LOD Fading (defaults to OFF)
Removed excess vertical padding from livery selection dialog (also prevents double activation when closing the dialog)
PHYSICS
Further minor adjustments to tread friction fade with velocity for all compounds to LMDh / GTP, LMP2 (both gens), P1 (both gens)
Adjusted GT Open carcass bend stiffness
Cadillac DPi: Minor center of gravity height & diffuser adjustments; Corrected fuel tank size being 1L oversized; Moved default brake bias slightly rearwards
GT1: Revised Nissan GT1 aero efficiency
Oreca 07 (All models): Corrected front camber adjustment range asymmetry (no setup reset required)
Metalmoro AJR Nissan V6: Corrected missing TC & ABS aids in authentic mode
AI
Adjusted AI downforce bias, peak slip angles, mechanical grip & AI lateral movement rates for better high speed stability & less erractic AI movements in F-Vintage, F-Retro, F-Classic, F-HiTech, Group C& GT3 classes
Further adjustments to AI lateral movement rates for F-Retro Gen1, F-Classics, GT3s
Sigma P1 G5: Reduced AI DRS drag scalar to mitigate risks of AI veering off track following front DRS activation
Adjusted AI dynamic corridors for Bathurst 1983, Silverstone 1975, Taruma Chicane
AUDIO
Fixed wall reflections and missing engine samples for Sigma P1 and Ginetta G58
VEHICLES
