Asus has begun rolling out beta BIOS updates to deal with widespread stuttering and efficiency points on ROG laptops. The firm confirmed September 26 via X.com that it had recognized the basis explanation for the bug and can launch finalized firmware starting in early October. The first trial updates will likely be out there for choose configurations of the 2023 Strix Scar 15 (G533ZW) and 2023 Zephyrus M16 (GU604VI).
The BIOS updates arrive after weeks of person stories detailing constant system-wide points, audio crackling, and enter lag on ROG notebooks. Asus initially mentioned it was investigating the issue, however has now confirmed that engineers have “isolated the issue that causes stuttering and performance interruptions.” According to an announcement shared by ROG North America, the corporate has begun posting beta BIOS variations for the affected SKUs, which is able to seem on official assist pages “in the coming week.” Asus has acknowledged that putting in the beta is not going to void guarantee protection. Expand the tweet beneath to see Asus’s assertion.
Reports of the issue began to surface earlier in September, with ROG laptop owners describing repeatable system-wide stutters occurring every 30 to 60 seconds under idle or light load.
A detailed investigation published on GitHub by user Zephkek attributed the issue to BIOS-level ACPI interrupt storms and improper power cycling of the dGPU. Windows performance traces and LatencyMon logs revealed elevated DPC latency associated with ACPI.sys, with a single CPU core consistently experiencing high load. The bug appeared to affect multiple laptop generations from 2021 to 2024, including high-end models such as the Scar and Zephyrus.
The company has not yet provided technical details about the root cause, although it now states that it has implemented a fix in the trial BIOS builds. The beta BIOS for the Strix Scar 15 and Zephyrus M16 is not currently available on Asus’ support site at the time of writing, but affected users are advised to check periodically throughout the week. Asus states that it expects to start rolling out finalized firmware updates for other models in early October.
Users who choose to install the beta BIOS should back up their settings and review the relevant change logs. While Asus has guaranteed that warranty coverage remains intact, test firmware can still carry risk and may not be as stable as the final release.
