Valve Defuses NVidia Half-Life 2 Issues

suineg writes "Gabe Newell, Valve's main man, has commented on Half-Life 2 and anti-aliasing problems with DX9 cards over at HalfLife2.net: '[The current problems] ...will look like a bright or dark line on the edge of a polygon. This is not a new problem. Artifacts may show up more frequently in Half-Life 2 simply because we've eliminated lots of other artifacts, and because we have a lot of variation in scene lighting due to our art direction.'" As far as solutions go, Newell has some: "ATI has supported... [the centroid work-around] form of anti-aliasing for the 9000 series... [as for] NVIDIA's [hardware], that doesn't support centroid sampling... you trade off some pixel shader bandwidth to clamp the texture coordinates."
