Parsec leverages the latest technology to deliver the lowest latency streaming experience available.

At Parsec we’re obsessed with latency. A weak implementation, even a single oversight at any stage of the video processing pipeline, can add latency that takes a cloud gaming experience from awesome to unplayable. Here are some of the components we’ve focussed heavily on:

Capturing

  • Low latency desktop capture with zero-copy GPU pipeline to encoder

Encoding

  • All hardware-specific encoding libraries implemented directly on Windows (AMD, Intel, and NVIDIA) with library specific optimizations

Networking

  • Low latency proprietary UDP protocol
  • Ultra-responsive dynamic bitrate adjustment
  • DTLS 1.2 with AES128 or AES256 cipher
  • Secure per-connection tokens signed and authenticated with Parsec
  • NAT traversal using UDP hole punching for peer-to-peer use cases

Decoding

  • All hardware-specific decoding libraries implemented directly on Windows (AMD, Intel, and NVIDIA) with library specific optimizations
  • Hardware decoding on macOS
  • Hardware decoding on Raspberry Pi via OpenMaxIL

Rendering

  • Zero-copy OpenGL rendering pipeline from decoder
  • Low level frame timing and synchronization optimizations
