Laggy UI (Graphics Card and DirectX level fixes do not work)

Hello. I am trying to play War for the Overworld, but I keep getting a rather frustrating lag with the UI, both at the main menu and in game. I have tried disabling V-sync and SSAO, as well as forcing directx 9 and 11. I do not have access to an AMD or Nvidia control panel, as I am actually using an integrated graphics card (and still get a decent framerate in-game. It's just the UI that lags).
