A Wired-First Strategy for PCVR

The Context

WiFi video streaming for PCVR becomes unreliable in warm ambient conditions, breaking development sessions in summer.

The Problem Statement

WiFi drops and latency spikes interrupt VR development iteration. There is no policy that makes wired USB-C or DisplayPort the default connection path for PCVR headsets in the V-Sekai studio setup.

Implementation

  1. Check whether the headset is connected via USB-C or DisplayPort.
  2. If wired, stream via the wired path.
  3. If no wired connection is detected, fall back to WiFi and log a warning.

The Downsides

Wired connections limit physical movement to cable length. Cables long enough to cover a full play area cost more than short ones. Motion trackers cannot use this strategy — no wired tracking option exists at the project’s budget.

The Road Not Taken

Dedicated 6 GHz WiFi hardware (WiFi 6E access point, per-headset channel reservation) eliminates most interference issues without cables. Rejected on cost: the hardware exceeds the studio budget for a problem that wired connection solves for free.
