Sorry, I meant DE1. I looked in the floor plan editor, and removing this pin doesn't change the routing of the other signals that much. Actually, not much seems to change at all, it just doesn't route the VGA pin. I have no constraints set up for this simple project, and all the pins are on LVTTL. I guess I'll have to probe signals on different pins with the scope and see if something changes when I change pins.
