Joeharkay The "advanced launch options" box is where you put command line arguments.
After yesterday's update, your game should be using DirectX 11 by default, since the issue with dual-GPU laptops was patched. Please double-check that that's what you're seeing though.
Since you're still getting crashes, please try playing with your computer offline. You can sign into the EA App and put it in offline mode, then disable wifi and/or disconnect the ethernet cable before pressing Play. If that doesn't help, please post a new dxdiag.
