Could you please provide us some details about your hardware details or console?
Open your Origin client, head over to your "My Games" library, click with the right mouse button on your Titanfall icon and choose "Repair Install".
Please check if there is an update for your video-card driver available. If you run a Beta version of your driver, revert to an older or release version. You should update your Direct X and install the the latest version of Microsoft .NET framework.
Please keep us updated.
