After I posted the topic over here. I thought of asking the EA Help.
This is what they told me to do:
Thank you for contacting Electronic Arts.
I appreciate your interest in Mass Effect 3. I understand that you are facing problem regarding frame rate dropping while playing the game.
I understand how irritating this could be. Do not worry I will definitely assist you. This is an online connectivity problem.
To get this resolved, I am providing you some troubleshooting steps. I request you to please perform the given steps accordingly.
PC Online Connectivity steps:
Disable firewall and antivirus:
I request you to temporarily disable any firewalls you have running on your system: - • Software firewalls can simply be turned off, usually by right clicking on the icons near your clock and selecting "Close" or "Exit". • Hardware firewalls should be bypassed by going from the computer directly to your modem, skipping any router you may have.
Please try power-cycling your modem. For this, switch off your modem and leave it un-powered for about 2 minutes then re-start the modem, this should power cycle your modem.
