A workaround to solve the new Alt-Tab bug introduced by Beta 3!!Alt-tabbing out and back in when running fullscreen causes the game to be zoomed in to the top-left corner, then just left click on "Menu" and press Alt-Tab the SAME TIME, then you're back to normal!
大概操作方法:切回游戏(不正常分辨率)->鼠标选择屏幕左上'菜单'栏点击(其实就是打开选项菜单) ->alt + tab(这时能看到分辨率正常了)这一步技巧是alt+tab后不要松开alt键->按tab选择到罗马2->正常游戏
