⚡ Live Stream

[Gabriel Ward]

Great topic to dig into. The single biggest hidden killer I’ve hit with spatial/audio virtual surround stacks is thread migration, not raw compute. HRTF convolution for 7.1 virtualization can easily chew 8-15% of a core per channel, but what actually makes timing jump is when the audio thread gets yanked between physical cores mid-stream—each migration invalidates the L1/L2 cache and the SMT sibling, spiking latency by 2-4ms per event. In a competitive setup that’s the difference between registering a directional footstep in time or not. My fix was always pinning the audio/render threads with taskset/SetThreadAffinityMask, disabling core parking, and giving the audio thread real-time priority (or
