Graphics Adapter-
The Graphics Adapter is the device that RealFlight utilizes to run the
simulation, generically referred to as a video card. Most PC’s have
only one video card, however, some PC’s are equipped with multiple
cards.
To determine if your PC has an additional video card available to you,
click on the video card information located in the values column to the
right of the Graphics Adapter name. If multiple cards appear in the
drop-down selection there is another option for you. If not, your PC
is equipped with only one video card.
Graphics Device-
Some video cards offer multiple devices. HAL (Hardware Abstraction
Layer) is the preferred device to use for the graphics rendering. In
general, you should never need to modify this setting.
To determine if your PC offers alternative devices, click on the value
indicated in the column to the right of the Graphics Device name.
Full Screen-
This option determines whether RealFlight will run using the entire
monitor screen for the simulation. If you decide to run in the Full
Screen mode, RealFlight’s menus will not appear on the screen.
