    • OBS config info (canvas width and height, frame rate, encoder width and height, which GPU OBS is using, VOD Audio Track setting, OBS version)
    • CPU info (name, speed, core counts)
    • GPU info (model, memory, driver version, device ID, vendor ID)
    • Memory info (free, total)
    • OS info (name, version, arch, emulation)
      • Windows info (gaming feature status: Game Bar, Game DVR, Game Mode, Hardware-accelerated GPU Scheduling)
    • Multitrack Video settings (maximum streaming bandwidth, maximum video tracks)
• Added support for Enhanced RTMP/FLV multi-track audio and video [palana/kc5nra]
  • Replaces the old metadata-based "VOD Track"
