Needs more ubers.
CD Projekt's RPG The Witcher 2 is set to launch in a matter of days, but already those who pre-ordered the game on Steam can now take a peek at the game's readme. Doing so reveals a very long list of graphics options, one of which in particular stands out: "Uber sampling."
As you'd expect, it's a high end option: "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)." The developer says this is intended only for those with both the best possible CPU and GPU available now (X4 980 / i7 980X and 6990 / 590).
Aside from that, count on options for textures, shadows, lighting, LOD, bloom, anti-aliasing, blur, depth of field, "vignette" (a strictly aesthetic effect), rain, SSAO, motion blur, animation, decals, and vertical sync. Keep in mind, this is just the short version.
A few of the above options are noted to be quite demanding as well, though not much compared to uber sampling. In any case, it's great to know although the system requirements are relatively modest, the studio is including bonuses for those with even better gear than what's listed.
