Changelog

New features, options and improvements

• Massive CPU consumption for physics thread fixed;
• Physics getting frozen fixed (but now, if physics workers aren’t responding in 3 seconds, CSP will crash);
• Few fixes for Rain FX and puddles generation misbehaving in some races, or outside of marked areas;
• Rear mirrors breaking on some cars when Smart Mirrors are paused fixed;
• Cars using original physics now use Embree for tyre-track contacts detection as well (still ignoring back faces, like original AC);
• Render Stats:
  • A tool to generate detailed performance report;
  • Some details about frames pacing;
  • Main performance plot adjusted;
  • Physics tooltip shows time taken by collisions detection;
• Underlying physics engine:
  • Back to OPCODE, now with a few optimizations;
  • Collisions with walls without thicknesss and other strange geometry should work better;
  • Car-track contacts getting more rigid with depth now do it better, preventing cars from phasing through walls or ground when pushed;
  • New physics experiment tweaking collisions between dynamic objects to stop Assetto Corsa from dying when a few cars are touching;
  • New physics experiments for faster collision checks (replaces old Kunos track subspaces — which, it seems like, few modders are using anyway — with something a bit more automated);
  • Multiple tyre contact points are faster;
  • A bunch of internal ODE optimizations;
  • New physics experiment adding collisions between wheels and cars (very experimental, disabled by default);
  • Track objects with multiple colliders per object, and intercollision enabled, should function better;
• Some of screen-space lighting effects (sparks, flames, cars) work if scale is different from 100%;
• Light from exhaust flames no longer disappears when AC is paused;
• Frames timing implementation (Sleep/Timer/…) adjusted to smooth things out, high resolution timer for rendering now spins a bit to even out the frames better;
• Welcome message showing up empty in some configurations fixed;
• CSP INI parser no longer treats // as a comment if before there is either http: or https:;
• P2P 1v1 mode: fixed track existance check;
• physics.RigidBody: a bunch of fixes for crashes, awakening and more;
• Cosmic suspension failing to pass validation fixed;
