Notes:

1) With the use of VR hardware, the computer must support DirectX11 with an NVidia 960 class video card, or faster.
2) Generally speaking, many onboard video chips may not meet the hardware standards to operate the game. It is normally better to go with an PCI-E based video card as opposed to a built-in video chip.
3) The game is generally easier and more fun to play when a joystick is available.
4) Satellite connections to the game have latencies which make it difficult to do anything real time.
5) Video cards listed, are done so for the sake of performance comparisons and should not be taken literally.  Use the supplied make/model to compare to whatever you have in your computer for a performance basis.
