Sub-Millisecond Game Streaming: A New Codec Emerges
2025-07-29
A developer has created PyroWave, an ultra-low-latency game streaming video codec, building upon their master's thesis. Rejecting traditional motion prediction and entropy coding, it uses Discrete Wavelet Transform (DWT) and block-based encoding to achieve sub-millisecond latency (encoding under 100µs, decoding under 1ms). While the bitrate is high (100+ Mbit/s), it excels in local network environments and boasts excellent error resilience. Benchmarks against NVENC show PyroWave achieving superior visual quality in some scenarios, highlighting its potential for low-latency game streaming.
