The physics dispatch in Source 2 is one of those things that gets hand-waved a lot, so let me be concrete: the simulation runs on its own thread via the Havok hkpWorld, decoupled from the main game thread through a fixed-timestep accumulator (typically 60Hz sim regardless of render rate). The key optimization lever most people miss is the broadphase—S

The core difference really comes down to how the driver’s rear acoustic energy is handled. In a closed-back design, that rear wave gets trapped and reflects back through the driver membrane, which creates internal resonances and standing waves inside the sealed cavity—especially problematic in the low-midrange where you’ll often see a bass bump around 80-120Hz that isn’t actually in the recording. Open-back vents that energy, so the driver isn’t fighting its own

The core difference comes down to polling architecture and spectrum control, not just the frequency itself. A 2.4GHz proprietary link like Logitech Lightspeed, Razer HyperSpeed, or Corsair Slipstream runs a dedicated point-to-point connection through a USB dongle with custom firmware, letting you hit 1000Hz (1ms) polling—and now 4000Hz/8000Hz on flagships, which drops report intervals to 0.2
