In QGIS 3, What's the difference between "Do not filter (better performance)" and "Ignore invalid geometries"?

Both can be found at Settings > Options > Processing > General

Both are options to ignore invalid geometries during spatial analysis.

    Read it literally. "Do not filter" disables filtering, thus also invalid geometries are forwarded to processing. – user30184 Feb 3 '19 at 20:02
  • @user30184 thanks for the info. so what happens to invalid geometries if they are still forwarded to processing? could that lead to some errors? – csft306 Feb 4 '19 at 17:07
  • I would guess that it depends on what algorithm is the next on the row and how sensitive it is. – user30184 Feb 4 '19 at 18:59

"Ignore invalid geometries" is poorly worded -- this option should be "Skip features with invalid geometries". Selecting it causes those features to be skipped over, just like they don't exist.
