Ratchet and Clank Future: Tools of Destruction [BCES00052]

I'm not sure what's going on here, but my CPU is basically doing nothing, and my GPU is not doing much either.
GPU usage is only around 41% (running 1280x720), but my CPU (Ryzen 2700X) is only having 1 maybe 2 threads used.
I'm assuming this is a limitation of the emulator at this point?
In scenes where the FPS is higher, like looking down and getting 40-50 fps, I see more thread usage. Total CPU usage still hovering around 18-20%
