ROG Strix G16 (2024) – Sudden GPU Power Drops Every Few Seconds in All Games

Laptop: ROG Strix G16 (2024) – G614JZR
Specs: i9-14900HX | RTX 4080 Laptop GPU | 330W ASUS adapter | Win11 Pro 22H2
Drivers: NVIDIA 552.44 (clean-installed with DDU) | Armoury Crate 5.9.4

Issue:
In every game I play (Cyberpunk 2077, Apex Legends, etc.), the GPU power suddenly drops from ~130W to ~25W for about 1–2 seconds, causing FPS to drop from ~150 FPS to ~5 FPS. Then it recovers. This happens every 5–10 seconds.

HWiNFO shows “PerfCap Reason = Pwr / VRel” exactly during each drop. Temps stay under 82°C.
I’ve already tried:
– Clean driver installs (multiple versions)
– Resetting Armoury Crate settings
– Disabling all undervolting
– Running without Armoury Crate or background tools Still no fix.

Welcome to the forums, newcomer!

Check to see if your laptop is pending any BIOS udpates.

Win11 Pro 22H2
The latest version of Windows 11 is 24H2, you have updates pending on your OS.

Drivers: NVIDIA 552.44
The latest version is 576.52; https://www.nvidia.com/en-us/drivers/details/245674/
I'd use DDU to remove all GPU drivers(intel, AMD and Nvidia) in Safe Mode, then manually install the latest driver version sourced from Nvidia's support site in an elevated command, i.e, Right click installer>Run as Administrator.

Thank you very much for the tips! I went through each one:

• BIOS – confirmed I’m already on the latest release for the G614JZR.
• Windows – updated to 24H2.
• GPU drivers – used DDU in Safe Mode, then installed 576.52 as Administrator (no Intel/AMD drivers left behind).

Sadly, the power-drop/FPS-dip issue is still there.

After several weeks of log-sharing and remote sessions, ASUS support now suspects a Windows-level glitch and recommends a completely clean reinstall. I haven’t reformatted yet because of work deadlines, but I plan to do it when things calm down and will report back with the results.

Appreciate the help!
