It heavily depends on the airport. E.g. TXL is horrible (depending on the terminal) and even an hour before at peak times isn't enough. Time of the day (e.g. mornings are usually peak times) matter as well. Luggage drop-off is usually until 45min before departure, same as in the US. Would love to see some data that quantifies that and recommends when to be at the airport depending on which terminal/gate, status (e.g. priority or TSA Pre), checked in or not, luggage drop-off or not, etc.).
