I had an ATI 9200 gfx card, the effect did NOT show with it (yes, I looked, and looked and looked.. not a pixel was changing.. my first though was that maybe it was a feature not yet implemented.. and I have a very trained eye having done comp gfx for 20 some years). During my re-remake I stopped in the middle (second thought.. maybe my card just wasn't showing me something I needed to see) and upgraded to a card with shader 3 and the effect did show. It is very subtle, but that skin effect, and the face skin details.. the buttons that go up and down, both required the upgraded card to be visible at all.
