The snap (to grid) feature is actually always on. However the "grid" has no visual clue besides the regular bar/beat line divisions. Take care that all editing of clips in the main tracks view and all events in the MIDI clip editor do snap to the current snap-to-beat setting, that innocent drop-down list that stays in the tool-bar or accessed through the View/Snap menu. The default resolution is usually set to "Beat/4" which means one fourth of a quarter note (16th). I guess if you select "Beat/2" you'll get the 8th you asked as well. The snapping is thus disabled by choosing "None". That will get you down to pixel resolution.
