Bloated OEM Audio Software Suites & High DPC Execution in RTKVHD64.sys

Motherboard manufacturers package Realtek drivers with heavy audio effects (Nahimic, Sonic Studio, DTS) that run continuous background tasks and spike DPC latency above 1000us.

In LatencyMon, RTKVHD64.sys frequently appears as the single worst culprit for execution latency. These spikes cause audio crackling, delayed gunshots, and frametime hitches. We strip out Nahimic and Waves audio bloat, switch to high-performance clean Realtek or Microsoft Generic High Definition Audio drivers, and configure MSI-X interrupt affinities.
