Generally, "high performance" is what causes the glitch. In this mode, nVidia optimizes their driver for maximum fps at the cost of image quality. There are a total of four modes: "High Performance"; "Performance"; "Quality"; and "High Quality". Despite these modes, some quality and performance features, such as anisotropy and antialiasing, operate independantly.
Worse, the optimizations are numerous, not well-documented, and are selectively implemented: The drivers have built-in presets for myriad (published) games so that optimizations can be engaged, or are prevented from engaging, when necessary. This is of course no help to a game such as Dwarf Fortress; Where no preset exists, the "performance/quality mode" is used as a fallback.
Where there exists no preset for the game or app you're running, the "mode" dictates what optimizations are engaged: All in "High Performance," none in "High Quality," and differing amounts in between. And from what I can tell, the parts in between are continually tweaked from one driver revision to the next.
