Hello,

I bought the game yesterday on steam and whenever I start the game, "Input not supported" appears on the monitor.
I already tried this:

Right click the game in Steam, click 'Properties', click 'Set Launch Options' and then type: -w 1366 -h 768
(1366*768 is my resolution)

I hope somebody can help me,

Posher

Hey,

I got the same problem and found a tool to set the settings without game start.
