If you’re unaware, while PS VR2 officially supports PC VR through Sony’s official SteamVR driver, the headset currently lacks its standout features on PC, including eye tracking, HDR, headset rumble, and adaptive triggers.
Now, a team of programmers have released an open-source mod of Sony’s driver, called PlayStation VR2 Toolkit (PSVR2Toolkit), and it includes eye tracking, adaptive triggers for the Sense controllers, and 10-bit color depth support.
