I had the exact same issue in the Technical Test and in the Alpha. BRolf02 hit it right on the head: the game runs off my integrated graphics rather than my Nvidia GPU (970M).
Pull up Nvidia control panel.
Click "Manage 3D Settings" on the left.
Click the Program Settings tab.
Click "Add"
If you've recently had the game open it should populate near the top of the list. Highlight For Honor and click "Add Selected Program"
Use the drop down of "Select Preferred Graphic Processor" and choose your GPU.
Close and enjoy the game!
