    Hello friends !

    I was trying to increase the performance of my game. When I profiled the game I found a call named " EarlyUpdate.ClearLines" that causes 11 ms lag and destroys the performance. What is it? Of course I googled it and couldn't find anything useful so don't remind me "Just Google it ". Thank you for your support

    Good question! Looking into the code it does clean up of Debug.DrawLine operations.
    More likely there are quite a few operations which need to be iterated. Sorry it is not clear in the Profiler.

    Thanks a lot! My performance is great now. But I really wonder why this call is in player loop ? I think it will be more clear if unity calls it in the editor loop. And do debug calls affect release builds? ( because it's in player loop ?)

    Debug.DrawLine is only doing work in the Editor, it does nothing in both release and development players.

    Good point! As I understand it is called from Player Loop as it has a logic which is attached to the timestamp and should be executed in sync with a Player Loop. Perhaps we could mark it as EditorOnly sample to simplify understanding
