2020.3.13f1 Release Notes


  • Asset Import: Improved mobile ASTC texture compression performance (about 3.5 times faster now).

  • Editor: Opening scenes with ASTC compressed textures (e.g. while in mobile platform) is faster now; the ASTC decompression is about 7 times faster than before.

  • iOS: Ignore plugins with wrong CPU type when creating xcode project, e.g. when building for run on device, libraries having CPU type "x64" (i.e. simulator libraries) will be ignored

  • Scripting: Update com.unity.ide.visualstudio to version '2.0.9'.

  • Shaders: Improved logging when compiling shader variants. (1338590)
