Tsuz: Thanks it works.
Though it causes more problems for me, like screen tearing, dodgy sound and sometimes the game can crash.
-window does not put the game in a window, it just makes the game look worse with screen tearing lol...... Nevermind.
I doubt the game was ment to be played outside its exclusive environment, which is what you are experiencing.
It does put the game in window mode (as opposed to exclusive fullscreen mode, which is
another beast). What it does however is scale the window to it's maximum size.
One last thing you could try out is adjusting the compatiblity setting, but I doubt it'll help much, sadly :<.
