Sections with tables all use a unified rating system for feature support (with one notable exception). Which options are available depends on the current parameter involved, as many are limited to only support or allow those states that are relevant to the parameter in question.
There are seven states in total:
true: This feature can be configured natively (in-game or through the game's launcher or configuration/setup tool).
limited: This feature can be configured natively, but support is limited (e.g. anti-aliasing is only on/off rather than giving a choice of quality levels).
always on: This feature is always active and cannot be configured natively (e.g. forced anti-aliasing). This state is not available for settings this concept does not apply to.
false: This feature is not present and cannot be configured natively (e.g. the game does not use anti-aliasing and has no option for it).
hackable: This feature can be added or configured via modifications, console commands, etc. This state overrides any of the other states.
n/a ("Not Applicable"): This concept does not apply to this type of game.
unknown: Support for this feature has not been verified. This is the default rating for all fields.
