Why does frame drop and audio lag appear during multiplayer combat?

Multiplayer combat suffered from 0.5s audio latency and frame rate dropping to 75 FPS. OBS monitoring revealed CPU usage spiking to 85% due to Logitech G HUB background sync conflicts. I used GamePP Peripheral Driver Conflict Detector to set service startup to Manual. Verification via OBS showed frame generation interval stabilized at 7-10ms, and frame rate recovered to 115-120 FPS, ensuring competitive responsiveness.
