Default Optimizing REAPER for large number of tracks

Do this experiment:
Empty project, no scripts running. Create 2000 empty tracks.
Look at your RT CPU usage. Hardware fans start to work hard and GUI is slow too. Why? There is no audio or anything. Just empty tracks. Playback is stopped. GUI is slow to just select a track. Maybe CPU is being used to draw all 2000 tracks even when I can only display 20 at once on screen?
Try muting all tracks and set the preferences "Do not process muted tracks". No difference. So CPU is processing something else, not audio.
What is going on? How could this be optimized?
