Changelog

New features, options and improvements

• Double precision physics engine to improve physics and FFB on large tracks;
• New Origin Shift feature in Graphics Adjustments, fixing visual shaking on large tracks;
• New generic configs affecting all cars and tracks;
• Major rewrite of advanced culling to improve its performance;
• DXGI tweaks got a few more options (unrelated to flip model):
  • Use GPU based on selected screen in AC video settings;
  • True borderless mode;
  • Triple buffering and custom maximum frame latency;
• Option for SIMD-accelerated visibility culling for tracks;
• Option to disable audio if AC is minimized or in background;
• Smart mirror: option to override mirrors rendering distance;
• Radar app: settings for colors, updated look;
• Loading smoothness and informativeness greatly improved, thanks to new built-in loading profiler;
• Loading should be faster now, with option to speed it up further with caching (enabled by default);
• VAO darkness fixed with dynamically adjustable gamma;
• Reworked crash messages, now with additional checks and tips;
• Crash reports include CSP settings preset;
• Sound speed takes temperature and other stuff into account;
• GUI: optional warning for throttle and brake pedals overlap;
• Custom colors online now saved across sessions;
• Option for adaptive near clip plane to improve the look with camera far away from cars and track;
• Custom VR mirroring: new modes showing right eye only and showing both eyes without distortion;
• Teleporting destinations list is more compact, supports grouping and can filter points;
• Post-processing refraction improved;
• Broken glass shader reworked once more;
• AI-related crashes on tracks without properly recorded AI splines should be fixed (they would just stand there);
• Online: admins now can assign penalties manually (needs a server requiring 1476 CSP build or newer);
• Car height map is used now to determine if free camera is inside a car;
• Other cars lighting up your car from behind now produce extra light from rear view mirror;
• New shader for heads of drivers (only non-skinned version at the moment) for more dynamic look;
• Doors animation and pit crew person with sign pauses with AC;
• Fake ambient shadows for tracks set via config, to add some darkening under those stationary cars;
• Small tweaks: option to adjust distance between eyes for VR just in case;
• Few small optimizations.

Fixes

• Fireworks audio and visual fixed, now reflecting in cubemaps;
• Arcade brake light traces: improved look, blending and behavior, optional position and size;
• Crash with mouse steering on certain tracks with very short AI spline fixed;
• Mirrors breaking and cockit switching to LR version with F6 cameras when other cars are close fixed;
• TyresFX no longer breaks after session restart;
• Inverted reflections (for example, causing black blobs on some tyres at night) fixed;

• Deactivation of sun shadows occasionally malfunctioning is fixed;
• Accumulation screenshots:
  • Cockpit details fixed, other smaller fixes;

• Few smaller fixes.

Configs

• TyresFX: specify tyres pattern for certain tyre types in config;
• Extended physics for cars:
  • Option to use real mass online to improve collisions for heavy cars;
  • Options to redefine collision parameters;
• Extended physics for tracks:
  • Option to use real mass for cars online;
  • Options to redefine collision parameters for different surfaces;
  • Option to use rigid collision between surface and car mesh colliders, to try and prevent cars falling through in some extreme cases;
• Extended raytracing for advanced tyre collision detection uses fewer samples to speed things up;
• INIpp: includes now can be optional, with expressions for file names, new functions to access and modify stuff that’s already been parsed;
• New inputs for read() for car and track configs;
• New parameter SHOW_IN_REFLECTIONS for track lights (please use it carefully, by default only lights with range above 10 meters is included to speed things up);
• New filter keywords: insideWheel, insideSuspension for nodes, driverPiece, isTextureDefault:<texture name> for materials;
• Car lights: tint for high and low beams;
• Car lights and custom emissives: separate lag up/down, custom heating color and other parameters;
• Setting set observeDigital 1 shouldn’t crash AC now;
• Car debug app now shows aero fan forces;
• Optional higher tessellation rate for flags, with tessellation applied to shadows as well;
• New semi-transparent shadows mode: NORMALS, taking into account surface to attenuate sun light for grazing angles, great for bent glass;
• CSP renders car window meshes late to ensure correct visuals: filter for such meshes now can be changed to include custom banners and such;
• Objects Inspector app:
  • Select skinned meshes;
  • Surface normal in click point is shown now as well;
  • Extra tool to simplify creation of fake ambient shadows for tracks (click button … when nothing is selected);
• Photoelastic PBR glass now supports multi-emissives as well.

Lua & Python

• Python function ac.ext_loadIniFileAsJson() fixed, ac.ext_parseIniFileToJson() renamed to ac.ext_parseIniAsJson() (old name also works for compatibility);
• New Python and Lua functions to get track’s coordinates, timezone and to check if WeatherFX is active or not;
• New Lua functions: ac.getSoundSpeedMs() to get accurate sound speed, ac.getAudioVolume('key') to get audio volume level;
• New WeatherFX Lua function: ac.setVAOExponent(gamma) to set gamma for vertex AO;
• Lua audio events got a new pitch parameter;
• Lua Debug App updated: copyable stored and debug values, clickable files in error messages (opening file at correct line for supported editors);
• Standart Lua libraries now shipped in bytecode form to optimize loading.
