I am running a Lenovo Yoga 1 Intel i7. I really like this game on touch screen, but the "Large UI" option does not seem to be working. Everything is the same size as when it is set to small? I have restarted the game as told to, the settings now say it is in Large UI mode but all options, menues, and fonts are still the same size.
Also is there a possibility of getting an in game keyboard pop up for touch screen mode? Right now I cannot play the game as a tablet, I have to keep my laptop filled around like a laptop. I really like how in Civ5, they have specialized commands specifically for people like me 
Let me know if I am doing something wrong, otherwise, I hope this helps.
