Low CPU/GPU usage when rendering, but it's different this time

There are a fair amount of posts about this similar problem, but literally none of them have a solid answer or just say "it's your hardware." The thing is that my hardware's been rendering fine with high usage for the last few months up until within the past week, where since then, it's been hovering at around 10% CPU/GPU usage while rendering a 1080p60fps h.264 file with either hardware or software encoding (tested both, same results), so I have no reason not to believe that it's a software thing, but that never seems to be brought up in these threads. 

I've tested rendering with multiple projects, from effects-heavy sequences, to just raw footage, and switching between software/hardware encoding, and I've only ever gotten low usage % on all of these, all ranging from 8%-13% on both CPU or GPU.

I'm using Premiere Pro 14.5 and I have a Ryzen 3700x, RTX 2060 Super, and 32gb DDR4.

I've updated my drivers already, I've restarted Premiere as well as my PC multiple times, and I've even attempted rendering in Media Encoder, which gives me the exact same issue of low CPU usage. I've even set both of their priorities to High and affinities to All Processors in the Task Manager, neither of which have really affected the usage %.
