Sections with tables all use a unified rating system for feature support (with one notable exception). There are seven 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 on/off rather than giving a choice of quality levels).
Always on: This feature is always active and cannot be configured natively.
False: This feature is not present and cannot be configured natively.
Hackable: This feature cannot be configured natively, but can be added or configured via modifications or console commands.
N/A ("Not Applicable"): This feature does not apply for this type of game.
Unknown: Support for this feature has not been verified. This is the default rating for all fields.
