just got my new system76 machine and it has really weird gpu clock behavior under load, running furmark (native) for testing and getting decent framerate for a few seconds, then the gpu core clock throttles briefly before ramping back up? it's causing really weird frame pacing where it'll be <10ms for about 2s, then 300ms+ for a few frames, then back to full speed. temperatures look fine, and nvidia-smi confirms the core clock goes down as low as 26MHz when this happens. tried updating to the 565 series drivers and the same behavior :(
