Original editor has always 0 cpu usage, only when you change block or move mouse or rotate the scene it gets a bit higher and after that its 0 again.
I would gues that they might be rendering the whole scene into some chached texture and then finally rendering that texture to the screen.
By doing so they need to recreate the sceene only when there has been some change done to the map or when you change your viewport. This could save lots of computational time.
