Please note the word "If" meaning that, under the situation you might be calling bump mapping geometry effects (which they are)... then all well and true. I did not SAY geometry=bump mapping. As for the second statement I made, If "geometry" = "more complex objects" then no, shaders wont help, and = not so great for CAD, then YES, I withdraw that statement. It is wrong for Unified Shaders architecture DirectX10 Shader Model 4.0. It is only true for previous generation GPU.
