iVRy says PlayStation VR2 compatibility with Windows requires a series of smaller hardware components; Because DisplayPort AUX channel in PlayStation 5 is used for a lot of visual information. The computer gets this information from another source and needs a custom driver.
For the initial setup, iVRy used a Linux PC as an intermediate device and used parts from the first generation PlayStation VR that are used for motion tracking. It might be possible to do this on a Linux machine equipped with AMD graphics without the need for additional hardware.
iVRy says a special adapter is needed to connect the PlayStation VR2 to a computer. It is unlikely that companies will be willing to produce such an adapter.
