Slow scrubbing response and slow playback response

hi guys im running a toon boom harmony 17, and when im animating more than 1 Character with deformers on every drawing module, scrubbing and play back on my timeline is responding slowly, Im wondering if my rig is under powered? my power supply is just a small power supply inside my pc, does that have anything to do with the performance of my GPU? Thanks!

here is the link on my rig,
