Asus is diligently examining performance issues affecting various ROG gaming laptops, with models launched between 2021 and 2024 reportedly experiencing 'disruption in performance'.
Asus is currently investigating reports of stuttering issues on its ROG (Republic of Gamers) gaming laptops, including the Strix, Scar, and Zephyrus lines. The problem, which has been affecting users since at least 2021 and continues into 2024, was first reported by GitHub user Mohamed 'Zephkek' Maatallah in August 2021.
Maatallah's initial report concerned a G15 Advantage Edition Asus laptop, but the issues have since been reported across multiple generations of ROG laptops. The problems reportedly affect performance and user experience, with stuttering while watching YouTube videos, audio crackling and pops on Discord, and random mouse cursor freezes being common complaints.
In some cases, a single CPU core is bottlenecked by interrupt requests, which can last for as long as 90 seconds, hamstringing performance and making time-sensitive tasks stutter. Additionally, Maatallah discovered strange power cycling of the dedicated GPU, turning it off and on again repeatedly every 15-30 seconds.
Maatallah used the latency monitoring tool LatencyMon to investigate the issue further and discovered looping interrupts as part of the problems. He also found that the issues include a misunderstanding of interrupt context, mishandling of interrupt requests, and GPU power cycling that doesn't check which GPU is currently in-use.
Asus is looking into this issue and is expected to release a firmware patch to fix the problems for the majority of users. The company is yet to provide a specific timeline for the release of the patch. In the meantime, users are advised to monitor the Asus support website for updates.
