Remember that video that came out that showed off Source's badass-ness with High Dynamic Range Lighting? Where the metal and rooftop and ant-lion were all shiney and reflective? I've noticed this isn't in the game, or at least when I play it and I have a card that supports it (Radeon 9800 Pro). Any ideas on how to turn this feature on? or did they just remove it from these things? Any ideas? Thanks!
