Titanfall lag spikes every few secound

Could you please try disabling Origin In Game to see if the issue still occurs after this? You can disable Origin In Game if you go to the Origin menu in the top left corner of the client, then Application Settings and Origin In game.

I can relate to this, game worked fine on Game Time but as soon as I bought it's been lagging like hell over the weekend with under 50ms ping. There  is no difference playing in my native server (Southeast Asia) or a server halfway across the world with x10 ping, I still see teleporting AI and players.

Really!!! you offer this as lag improvement!! Do you know anything about computers. an overlay effects very little if anything. lag comes from pings on the server, rerouting from one place to another, or traveling in great distance to reach main server. Titanfall lag can only be killed with an app called internet killer offered by MSI motherborads, custom building a pc that will not overheat the core, or upgrading to a viable graphics card like the EVGA geforce gtx970. without a high end computer your efforts to enjoy pc gaming will always be in vain... I speak from too much experience

Please leave dead and buried threads in the graveyard.  The average noob confuses transmission delays, as defined, with local system slowdowns, which is quite obviously what the OP complained about.
