I have had an issue start today, and have changed nothing in any settings, in game or on my PC.
When i run the game in windowed mode, the screen is really dark (Ive always run the game in windowed and never had any issues) but when i run it in Full screen native resolution the brightness is fine! Taking screen shots always shows the screen as dark, as well as fraps.
I have a AMD HD6950 graphics card.
Any help would be appreciated, as well as any help why my fraps is so dark :p
