Hi people. Just bought the game, had the same problem.
So here is how I fixed it: - Either disable anything like a capture software or steam overlay. - Or go to Origin, right-click Titanfall, properties and check "disable Origin ingame".
You can have Origin ingame enable or your capture software/steam overlay/whatever, but not both.
It has already been said that it does not fix it, that fixes the whole game freezing, because of pc performance and bad optimization of origin overlay, not the issue people is talking about.
The game does not freeze, there is some kind of lag spike where you see the other players and minions frozen, but you can keep moving. It's a connectivity problem, that appeared with the last patch.
EDIT:
Guys where are you from? cause I was experiencing the problem using the EU west and north data servers. Just changed to US server and apparently there is no problem. So I can play now while they fix this, but its not a solution, I have 150 ping on US servers.
