PSVR 2 on the PC project has been implemented SteamVR to work, but there are important limitations

The PSVR 2 project as a PC VR HMD uses additional hardware to make the SteamVR output work properly.

PSVR 2 already technically works on PC without any third-party tools or drivers, but only in "cinematic mode" where it shows your monitor in front of you and only on certain Valid on NVIDIA 20-series graphics cards. On PC, this mode also lacks positional tracking.

iVRy was developed for the original PlayStation VROne of the third-party SteamVR driversThe developer, who has been experimenting since gaining access for PSVR 2 at the end of February this year.

The original PSVR was actually an HDMI display tracked by a stereo camera with light strips. In contrast, the PSVR 2 uses a single USB-C cable to transmit both video and tracking data, and iVRy has often openly pointed out that getting it to work as a PC VR headset will be more challenging.

In recent months, iVRy has publicly outlined the obstacles and potential problems associated with this,on their twitter pageAt times it was even suggested that the project might have reached a dead end, that the mission might be impossible. But recently they've been breaking ground trying to use a DisplayPort "sniffing" board to discover the exact video input format PSVR 2 expects to enter into VR mode, though with one important constraint.

Today, iVRy posted a screenshot that it claims shows SteamVR outputting to PSVR 2 on PC, at the headset's full 120Hz refresh rate.

The breakthrough here, however, is the use of additional hardware and custom software between the PSVR 2 and PC.

Sony has hard-coded the PSVR 2's VR image output parameters into the PlayStation 5, but the NVIDIA and AMD display drivers on PC don't have that information, and the headsets only provide them with Cinema Mode, according to iVRy. To solve this problem, iVRy programmed a Linux PC to set up a "middleman" that acts as a PSVR 2 in VR mode in the Windows PC's display driver and provides the necessary DisplayPort parameters for output.

This approach allows PSVR 2 to work on PC, but means end users will need similar hardware support.

Another limitation is that there is currently no onboard tracking – neither rotational nor positional. iVRy told us that the results of their research so far suggest that PSVR 2's tracking may be handled entirely by the HMD itself, so it may be possible to access it in the future. However, if iVRy doesn't have access to the PSVR 2's onboard tracking, users will have to use external methods like the SteamVR "Lighthouse" base station and Vive Tracker.

So, PSVR 2 can now technically work as a PC VR headset. But there's no tracking, and it requires specific custom hardware, and no company has announced an intention to mass-produce it yet.
