WhoÃ¢â‚¬â„¢s played, what are the options for the video settings? Is it exactly the same as Half-life 2's? I want to be able to reduce the graphics down enough for a 32-64 MB video card is that possible? What kinds of things can be changed? Shadows? Textrues and by how much? Low, Ultra Low, Very Really Ultra low? Can the res be changed?
