I'm not sure if this is the right section, so sorry in advance if it isn't.
On default (i.e. the very first time I played TMI) the game starts-off at graphical setting 4. The whole thing lags; even the mouse takes a good few 10 seconds to move from point a to b. What's so interesting is that as soon as I turn the graphics down to 3, it runs very, very smoothly. It's kind of ridiculous. I was wondering what graphical setting #4 activated that would basically choke my PC like that.
