Cyberpunk 2077 - GPU and CPU usage drops low every few minutes

Every 3-5 minutes or so, my framerate in Cyberpunk drops to below 10 fps for a few seconds. Here's a clip of what that looks like: https://streamable.com/rlp70n

The game otherwise runs smoothly with 60+fps. I initially was playing on High settings but turned some of it down to Medium, but nothing changed. Tweaking different modes of DLSS also did not change anything, although I haven't tried turning DLSS off completely yet.

It looks like my CPU and GPU utilization drastically drops for some reason when the lag spikes happen, then rapidly return to normal. Here's what my CPU and GPU usage look like while that's happening: https://imgur.com/a/JdFTkCg

Here's the benchmark statistics: https://steamuserimages-a.akamaihd.net/ugc/50200269957242691/C8510C9CE6B5C31E36B3F9F08D8F6DD651F01414/

My hardware: 2021 Asus Zephyrus G14 GA401, RTX 3060 Laptop GPU, Ryzen 9 5900HS CPU

Things I've tried: closing all background apps/tasks, restarting my computer, reinstalling NVIDIA drivers, verifying integrity of game files, lowering graphics settings, checking I'm plugged in, checking I'm using the discrete GPU

Any help is appreciated, thank you!
