Filter to find ALL populated servers:

This is a filter you should save, then tweak later to your liking:

From the main menu Home Screen go to Multiplayer > Server Browser > Filter

• Game modes: set to blank (tweak later)
• Maps: set to blank (tweak later)
• Classes/Vehicles: all fields are likely set to ON even though it looks blank. Change all fields to blank - not off, not on, but BLANK.
• Weapons: same as above - manually change all to blank.
• Advanced: same, manually change all fields to blank. Tedious, yes. But do it.
• Rules: same, manually change all to blank.
• Slots: select NONE (this will show the full servers), 1-5, 6-10, and 10+. Do not select ALL unless you want to see empty servers.
• Regions: set to blank (tweak later)
• Name: go into this field and make sure it’s blank. Don’t just glance and it seems blank, but check to make sure there’s no spaces or what-have-you.

Now save this filter before you go any further. Name it whatever you'd like (mine is named “ALL POPULATED”).

This filter will show you everything. From this filter you can create others (and save them), tweak fields such as region for lower ping, select favorite game mode(s), or specific maps you want to play. [This filter will sometimes truncate the list at 100 since there can be that many populated servers.]

The most popular game modes are Conquest, Operations, TDM, and whatever happens to be in the weekly rotation. On Friday nights, weekends, and holidays, you can often times find the less frequented game modes/maps.

Good hunting!
