Why have i the screen full light when i play Penumbra's sequel?
I have no dark. As full gamma but it isn't at full... Penumbra without dark isn't Penumbra . How can i fix it?.
Go through options from the main menu and see what the shader detail is. If it is Very Low lighting will be off and everything will be too bright. Try setting it to at least Low.
P.S. (Incase I'm wrong it might be under Options > Advanced).
