    the Unity editor has normal performance in edit mode, but has high cpu usage in debug mode. I test my game play after build, it only cost 3% ~ 6% cpu，the cpu usage in debug mode is 35%~40%, the profile window shows that 90% of cpu performance has cost on Editor.Loop shown below.

    I used Odin for editor extension, DoTween for transition, TexturePackerImport for sprite package and nothing else.
    anyone has idea about this? thank you first

    Hi @t_ree,

    What you're experiencing is actually normal, the EditorLoop is everything that's happening in the editor, not just with your game. You will often notice that the time it takes is longer than your PlayerLoop.
    The PlayerLoop is roughly your game performance.

    Ideally you want to be profiling your application on the target device.
    You can read more about how to profile your application here: Unity - Manual: Profiling your application (unity3d.com)

    Thank you for reply, It's not a big problem but actually make my cpu fan noise big, maybe version 2019.4 is a better choice for now.
