The Witcher 2 developer CDProjekt’s game will have graphics that are literally ‘uber’, as a new graphic option is listed in the game called ‘UberSampling’.
Despite being in DX9, the game will feature extraordinary graphics. As for the option called ‘UberSampling’, according to CDP, “The whole scene is rendered multiple times to give best possible texture and object details and antialiasing (better than antialias and anisotropy even on highest settings).”
In other words, you won’t need to set antialiasing or anisotropy because UberSampling will do it for you, only much better. Be warned, however, only high-end machines will be able to run the highest features.
