Please explain your issue is in as much detail as possible.
when i start the game i get a window to login, after press play i new window opens, but sadly not in fullscreen mode, i have the bar at the top and cant change the resoulution or fullscreen. i used start parameters as -popupwindow or -windowed but nothing fixed this, the problem is that the window stays at 1080p and on the left things are coverd from my toolbar and on the buttom the window goes beyond the screen i cant even see this things.
