Reinstalled HL2 last night. Played through Lost Coast with HDR (most settings on full and still 60fps on the stress test). Bought Episode One last night, so will try it tonight.
Not too tempted by the FakeFactory stuff - my PC just doesn't sound mega enough to work with them. I wish there was a medium res update (i.e. somewhere between default and super high). And no towels or silly vest tops.
Does anyone know if the basic HL2 storyline has been updated to HDR? I think it looks quite nice. A bit overdone in places, but these effects often are to begin with. And some of the things they plan to add to the Source engine (I read on Wikipedia) sound amazing. Source and Crysis will be head to head into DX10 days
