Gamers Nexus writes, "First person shooters are on the edge of coolness," said Tamasi at the conference, "and reality is a really, really hard thing to get right. We know what it looks like." It's been said before, but given the context of the discussion, he is absolutely correct. We are able to -- as both gamers and "real" people -- criticize things like smoke and shading technology because of our exposure to real-world environments where, of course, shadows and smoke originated. When playing cartoony games like Torchlight, however, it is much easier to overlook cell-shaded practices and any visual artifacts that could be passed off as "fitting of the theme." The inherent difficulty in reproducing actual environments within a 3D world has only spurred nVidia on to meet the challenge, urged Tamasi, "rapid iterations are the key to creativity.""
