In multi-sampling, there's a sample count (which is the number of samples taken) and a sample quality. The question is, is a higher quality integer better or worse?

Thanks.

The "quality" setting lets you select from various MSAA modes that are specific to the hardware. They don't necessarily correspond to "higher quality". The most common example would probably be Nvidia's CSAA modes, which are selected via the quality setting. D3D10.1 also added standard MSAA sample patterns, which you access by specifying D3D10_STANDARD_MULTISAMPLE_PATTERN or D3D10_CENTER_MULTISAMPLE_PATTERN as the quality level.

...So they're not actually quality, they're patterns.

Wonderful.

Thanks.

Well, they are 'quality' just not in a 'bigger number = better' way - the number is a way of selecting a hardware specific quality setting for the filtering.
