Full (Aspect ratio support)
From WSGFWiki
Definition
A game with "Full" aspect ratio support is one where it can display correct aspect ratios for 16:10 monitors and 16:9 monitors. That is, the horizontal component of the FOV can be 1.6 (16/10) times greater than the vertical component for 16:10 monitors, or it can be 1.77 (16/9) times greater than the vertical component for 16:9 monitors.
Examples
Half-Life 2 automatically uses the correct aspect ratio based on your resolution.
Doom III has a game variable, r_aspectratio, that must be manually set. A value of 2 means 16:10, and a value of 1 means 16:9.
