only having the one machine but the same software, I am curious do textures and materials appear differently on different machines? Off hand I would say yes as would not each of our machines bee made of different key components

that affect program clock cycles and time taken to produce textures or materials.
In that sense someone with a dual or quad core system and dual graphics card, woudl they not have equivalent qualitative textures with less rendering times and better with equivalent or more rendering times?
the reason I say this is because some materials were made for me and inmy scene they came up differently and in the end i chose to create the material I needed. At first I naturally assume because of my limited experience that it was my lack of knoledge about the application but on making my own material I realised that there may have been an error in my assumption.
Eg shaders that are used by 3ds max people at pixar on their boxes would respond differently to my humble little machine hahaha

what do you think?
