Factorio is attempting to start on your integrated graphic. (It is also attempting to use opengl rather than directX, but that shouldn't be a problem). Try to tell windows to run it your dedicated graphics. (You might also want to check for newer graphics drivers as well).

Your Intel graphics driver is quite dated, the latest version is here: https://downloadcenter.intel.com/downlo ... duct=97500

To make OpenGL use your Geforce GTX 780 Ti instead of Intel integrated GPU, you need to go to Windows' View display settings and set a screen that is connected to the Geforce as Primary.

To switch back to Direct3D instead of OpenGL, you need to edit force-opengl value in the config.ini. See: 9300

Thank you, Posila and Zavian!
Running nicely on the GTX card.
