typicalbeth_sims Your dxdiag lists a couple of BlueScreens and some other errors related to the graphics driver. I'm not sure they're related to this particular issue since it's happened to other players without any such errors. Let me know if you'd like to troubleshoot these though.
For the in-game graphics error, please test in fullscreen and windowed modes, in DirectX 9 mode, with post processing disabled, and with your secondary monitor disconnected. It would be helpful to test these separately and together, especially DX9 mode. You'd need to change the Nvidia Control Panel settings for TS4_DX9_x64 as well, since that's the executable that runs DX9 mode.
