NVIDIA Virtual Reality Capture and Replay (VCR) is a tool that allows developers and users to accurately capture and replay VR sessions. It records time-stamped HMD and controller inputs during an immersive VR session, enabling precise reproduction of the session without an HMD attached. This tool is particularly useful for performance testing, scene troubleshooting, and quality assurance.

Features

• Capture: Record VR HMD and controller inputs, configure capture frequency, and split tracking data into segments.
• Analyze/Edit: Use the VCR API to read and write recorded sessions, clean up data, or re-time HMD motion paths.
• Replay: Modify display resolution and refresh rate, adjust hardware properties via JSON files, enable or disable VSync, and replay tracking data segments in any order.

Benefits

• Accurate Playback: Accurately record and playback VR user inputs for performance testing and quality control.
• Efficiency: Save development time by avoiding the need to jump in and out of the HMD.
• Multi-Role Recordings: Sequentially capture multiple roles in the same VR scene using a single HMD and replay them simultaneously to simulate collaboration.
