      • 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)
