I want to report a bug: I’m using Editorversion 20022.3.6f1. I create an empyt 2D project, and import a asset like this: https://assetstore.unity.com/packag...mer-controller-with-animated-character-245475 or this https://assetstore.unity.com/packages/templates/systems/corgi-engine-2d-2-5d-platformer-26617 After importing I save and test the demo scene (playing the level in the editor), the framerate is stable at 120-140fps Then I close the project and Unity3d. After loading the project again, I test again the demo scene and then the framerate drops from 140fps to 60-70fps every 5-6 second. Both assets have the same fps-drop, on a 2D scene and at a 3D scene too. I don’t know why, is this a bug from the editor? I’m new on the unity engine I have no experiene with older version of unity. I used the profiler and the lag comes from the Editor-loop.
