To use FlyInside you'll need a flight simulator, a virtual reality headset, and a virtual reality capable computer.
Virtual Reality Headset
FlyInside requires that both your primary monitor and your HMD be connected to the same graphics card. This is because FlyInside shares data between your simulator, monitor, and HMD. Your HMD must be connected to the card's HDMI port. If your graphics hard has only one HDMI port, and your monitor also uses HDMI, you will need to use an adapter to connect the monitor to an alternate port. An HDMI to DVI adapter may be necessary.
FlyInside does not support SLI. SLI may result in crashes, flickering, or failure to function. Please disable SLI before using FlyInside.
