  • Option to set lower quality setting for left and right sides in triple screen mode;
  • Optional debug mode: hold Space to quickly switch to simple linear upscaling to compare;
• Smoke fully reworked (apart from tyres heating and spawning logic):
  • New improved shading;
  • Improved smoke-cars collisions;
  • Better support for open-wheelers;
  • Tyre smoke spawns below car with extreme drifting angles;
  • Dust and splashes spawns around car, not just from wheels;
  • Dust flies off dusty wheels;
  • A bit of dust appears for some F1 cars with wooden skidpads when those touch the ground (and can be configured on per-collider basis, similar to sparks);
  • Clouds of dust spawn on collisions;
  • Smaller particles for bits of dirt and smaller splashes spawn in contact points;
  • Long-lasting smoke and dust (lasts for several minutes);
  • When on grass, instead of dust clouds, more subtle soil particles are used (color is set in track config);
  • New look for smoke from exhaust, heated brakes and damaged engine;
  • Smoke won’t show up inside a cockpit;
  • Colored smoke and dust lose saturation with expansion, with new config parameters to adjust the rate;
  • Smoke culling improved for further optimization and smoother transitions;
  • New options to adjust density and on-screen size, to balance between visuals and performance;
  • Extra effect with smoke covering whole screen, to get effect of camera stuck in smoke much cheaper;
• Pieces particles update:
  • Adjusted types chances, size and shading;
  • Collision detection now uses car heightmaps instead of depth buffer for more accurate results;
• Size of sparks particles fixed, sparks no longer spawn with head-on collisions;
• TyresFX:
  • Grass and dirt on tyres reworked, textures and rendering both;
  • Soil color is taken into account;
• GrassFX:
  • Active ExtraFX pass option now properly supports fake car shadows reprojection;
  • Grass deformation updated, now takes into account grass height;
  • If you’re using original AC motion blur, it would affect grass as well now;
• New rendering modes: 360°, fisheye, split screen (new Content Manager supports custom modes for AC video settings);
• Specify joypad index for joypads input mode;
• Support for VAO patches v5 with spatial AO samples for dynamic objects;
• New sky mesh with more evenly distributed triangles for better reflections and mirrors;
• Option to hide console;
• Option to create portals to other servers online for freeroam servers;
• Scene tweaks from new photo mode app remain active in replay with app hidden;
• If VR failed to initialize, there’ll be a warning on loading screen (especially helpful if you accidentally chose wrong render mode);

• Chat shortcuts reworked: new UI system, now don’t trigger change in turbo, different approach for alternative set of messages;
• Option to unbind digit buttons from changing turbo level;
• Triple screen tweaks: option to always show driver name tags (with original system);
• Semi-transparent shadows from smoke, flames, semi-transparent objects and such improved with Bayer dithering;
• Button for manual control of speed limiter (with default session settings it would still be automatically engaged in pits, but it could be overriden in some cases);
• Walking out module: settings, improved transition, few fixes, selected car is the controlled one, tool for positioning cars a bit more easily;
• Freer camera: use pedals to smoothly control camera speed.

• Colorful shadowing: overall look improved, new parameters;
• Masking pass shading improved, doesn’t look as messy with darker textures, new parameters;
• Custom car physics:
  • Create hidden car setup items linked to some AC physics controller (for example, to create a suspension with ride height adapting to car speed);
  • Link clutch damage to exceedingly high torque;
• Custom track physics:
  • Soft walls fixed, with new MAX_DEPTH option to limit softness for collisions that are too deep (docs are coming);
  • Cars spawned aligned to track surface (optional, controlled by track’s physics config surfaces.ini, enabled by default with custom track physics);

• If you’re using wing animations to show and hide extra bits, now you can configure it so hidden geometry would actually be hidden, saving draw calls:
  • Car lights now can be bound to wing states, referencing wing ID and using LUT for brightness multiplier;
  • For simple cases with two states where hidden bit is either scaled down or moved far away, CSP should be able to guess things automatically;
  • Tool to quickly generate such animations with corresponding config is available on CSP wiki;
• When copying coordinates from Objects Inspector, hold Shift for extra-precision mode;

  • Script could be in a separate file (SCRIPT=script.lua, same as LUTs);
  • Access mirror texture to create displays with rear view camera and overlays;
  • Define new cameras (similar to rear view mirror) with optional post-processing and access them in script, for this like parking camera activating with reverse gear;
  • React to clicks on other meshes (optionally limiting area to certain UV coordinates), so they could act like buttons;
  • Change car state: switch headlights, high beams and extra toggles;
  • Control some of car inputs: alter ABS, TC, brake bias or turbo wastegate (could be used to create a dashboard similar to one of BMWs with extra car settings);
