    • 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);

    • 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;

  • GrassFX:
    • Active ExtraFX pass option now properly supports fake car shadows reprojection;

  • 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);
  • Semi-transparent shadows from smoke, flames, semi-transparent objects and such improved with Bayer dithering.
