 ASUS ROG Laptops (2021 to Day) Stutter because of Bad ACPI firmware Summary ASUS ships ROG laptops with firmware so BAD that it sleeps hundreds of milliseconds in interrupt handling code. It has drastic effects, stutters in day-to-day use while using dGPU. Mohamed Maatallah shares his deep dive in Github with analysis of ACPI firmware dump.   Quote You own a high-end ASUS ROG laptop perhaps a Strix, Scar, or Zephyrus. It's specifications are impressive: an RTX 30/40 series GPU, a top-tier Intel processor, and plenty of RAM. Yet, it stutters during basic tasks like watching a YouTube video, audio crackles and pops on Discord calls, the mouse cursor freezes for a split second, just long enough to be infuriating. You've likely tried all the conventional fixes: Updating every driver imaginable, multiple times. Performing a "clean" reinstallation of Windows. Disabling every conceivable power-saving option. Manually tweaking processor interrupt affinities. Following convoluted multi-step guides from Reddit threads. Even installing Linux, only to find the problem persists. If none of that worked, it's because the issue isn't with the operating system or a driver. The problem is far deeper, embedded in the machine's firmware, the BIOS.   This is really bad and ASUS needs to be hold accountable especially for people who fought with the warranty or thought it is normal to have this stutters.   Sources https://github.com/Zephkek/Asus-ROG-Aml-Deep-Dive
