What's new

1.4.9

  • Improved particle performance with Particle Core: more vanilla particles now tick off the main thread on 1.21.10+
  • Improved particle collision performance on 1.21.1+
  • Improved Flashback replay performance by not loading chunks for entities far from the player on 26.1+
  • Fixed a crash on the first frame with Vulkan on 1.21.11 and 26.1.x when using an unsupported Sodium version; Polydium now stays on OpenGL and logs a warning
  • Fixed the Vulkan/OpenGL choice being reset when switching between game versions that share one game directory (e.g. OneClient)
  • Fixed the game breaking every frame with Vulkan after a mod left a render pass open, including during Flashback exports
  • Fixed hitboxes and block outlines turning into huge triangles with Vulkan on 1.21.11 on AMD GPUs
  • Fixed "PreparedFrame already in use" errors every frame after a crash-recovery mod caught a render error on 26.2+
  • Fixed a crash with Iris shaders when glowing entities are visible to the shadow pass on 1.21.11 and 26.1.x
  • Vulkan is now unavailable on 1.21.11 with CatLean installed, as it only supports OpenGL
  • Fixed a crash when another mod queried Iris' config on the Vulkan backend
