New features, options and improvements​

  • VR update:

    • Single Pass Stereo, cutting number of draw calls by two;
    • Variable Rate Shading (aka foveated rendering) for NVIDIA 16…-, 20…- and 30…-gen GPUs;
    • Optional single YEBIS pass;
    • Support for corner masking optimization (stops shading in areas covered by lens to speed things up);
    • ASW 2.0 support for Oculus;
    • Also, for Oculus: CSP now updates AC manifest, updates assets to show details about the race, closes AC if its VR element is closed;
    • Better OpenComposite (previously known as OpenOVR) support, for both OpenCompositeACC and regular OpenComposite version (fixing crash with ipdOffset);
    • Crashes in VR now shut down AC first and show errors in a separate process, to make sure VR environment would switch back to desktop;
    • X-ray rendering for HUD to stop things looking weird if there is some geometry in front of HUD;
    • Controllers integration: interact with HUD, adjust rear view mirrors, use touchscreens, press car buttons and more (if car has those set);
    • Experimental option to get driver hands to follow VR controllers;
    • Optional extra dithering, might help with overly compressed image with Oculus Air Link;
    • FPS counter for custom VR mirroring;

  • Custom GamepadFX script updated:

    • Improved implementation;
    • Separate drifting and racing modes which can be switched while driving;

  • WeatherFX:

    • Various improvements for cloud covers;
    • Accurate moon eclipses (need to be enabled by WeatherFX scripts to ensure compatibility);
    • New API for implementation scripts to create custom effects;

  • Default WeatherFX script:

    • Distant thunder effects;
    • Rain haze;
    • Rain audio;
    • Auroras (try February of 2022 on a track further than 60° of latitude, such as Ahvenisto Race Circuit);
    • Fixes for fog, fog covering tops of tall buildings;
    • Size of planets, sun and the moon fixed;

  • Extra server options:

    • An experimental option to pause collisions for a bit if remote car would suddenly jump;
    • Explicitly defined timezone and coordinates to ensure lighting would match with custom tracks with no such properties defined;
    • Syncing of wheel angles now includes caster;
    • Custom cars motion fixed, now shouldn’t cause issues with remote cars acting slightly differently when colliding;
    • An extra option for custom cars motion: smooth motion for slower cars helping with cars shaking on larger tracks (can be activated with CUSTOM_MOTION = 1, SMOOTH);
    • Options to reset car if it got stuck in a collision or falling through ground, with optional penalty;
    • New core options: force custom cars physics, force custom track physics, hide pit crews to speed up loading (support in CM is coming soon);
    • Commands to show a message and override ban message, available as new direct TCP commands or compatible chat commands;
    • Issue with some of EXTRA_RULES values allowing to access setup menu without going to pits fixed (set new CSP build ID as a minimum required version);
    • New rule requiring to finish the lap before going through pit penalty (so people couldn’t reverse back through pits instead);
    • Set some CSP modules to be required for a server;
    • If server requires any CSP module using that option, or requires WeatherFX or RainFX using older methods, live settings reload will be disabled;
    • Option to hide default map app;

  • Features for custom server implementations:

    • Custom packet format: support for types less than a byte (CUSTOM_UPDATE_V2);
    • Batch update fix fixed (new ID is BATCH_FIX_V2);
    • Servers changing tracks often can specify FREQUENT_TRACK_CHANGES feature which will force CSP to update track ID to actual one before connecting;

  • Python:

    • Better errors handling;
    • Optional caching to speed up loading;
    • A compatibility fix: can help if installing an older app breaks a newer app (forces apps to use newest sim_info library);

  • New built-in apps (written in Lua):

    • Controller tweaks: adjust FFB, gamepad or keyboard control options during the race with changes applying live;
    • Mirrors configurator: adjust Real Mirrors with convenient sliders;
    • Setup Exchange: publish car setups, load and apply setups made by other people in pits (pits integration is disabled by default, can be enabled in app settings);

  • Remote cars no longer have their steering wheel angle limited by 127°;

  • CSP soundbank with sounds for wipers is included now;

  • Water shader: few fixes, new depth-aware mode for smooth blending, caustics (for both refraction and reflection);

  • New water drain shader for water in water drains filling with rain;

  • New rainbow stickers material for cars;

  • New ChromaFlair car paint;

  • New Planetarium filter (also, cartoon filter updated);

  • DDS textures now can have LZ4 compression applied to them to reduce file sizes;

  • A new experimental feature for creating custom external AI implementations;

  • New experimental chunks optimization mode increasing FPS on large tracks;

  • Basic chunks optimization now uses adaptive chunk size, increasing performance for tracks with smaller objects grouped in a separate KN5s;

  • Optional clearing of system shaders cache when CSP version changes (enabled by default, solves issue with loading getting stuck with some hardware);

  • Option to stop AC from creating setup folders for every installed track (also saves time during loading);

  • Option to pause rendering if AC is in background;

  • Option to use memory mapping for loading textures and VAO patches (might increase loading speed);

  • Option to use Time-To-Speech for chat messages online.

  • Accurate PBR materials for tracks with optional displacement (currently in experimental stage).

Lua​

  • Custom car physics script:
    • Access car state (ac.StateCar as car, it doesn’t update at physics rate, but for some things it should work all right);
    • Change CD_GAIN and CL_GAIN for wings;
    • Access and alter body damage and tyres inflation (set to 0 to blow them);
    • Access more of wheels state;

  • Lua apps now can create new UI elements for car setup, save and load setups, access setup items and change them;
  • When creating extra canvases, it’s now possible to specify format, including HDR formats;
  • Textures are now reference counted and unload automatically (you’d still need to use ui.unloadTexture() to unload textures used in UI);
  • Functions to render quads and quads with custom shader, function for optimized fullscreen pass for extra canvases;
  • Sim value currentServerTime stays synced with session change;
  • Access lap splits in sim state;

  • Scene API: new functions for basic set operations on scene references, async loading for new models;
  • Text inputs are no longer limited by 256 symbols;
  • Web requests no longer throw errors if URL is malformed, instead they return errors via callbacks;
  • New parameter for web requests to load headers only, without the payload (not all servers respect HEAD method);
