I bought Victoria 2 on Steam. When I select an unit (e.g. an army or a fleet) and the brigade list shows up at the left of the screen, the fps drops dramatically from 60 to 11. However, the game runs perfect when I do not select my army. So basically whenever I try to select and mobilize my troop to fight a war, the game begins to lag and it is unbearable. My laptop has an i7 6700hq CPU and 16GB RAM, with a gtx 1060 video card, which I believe have absolutely met the hardware requirement. I guess there is something wrong with the game file or with my laptop setting that I am not aware of. Has anyone ever encountered such weird problem and how did you fix it?
