my gpu usage never goes above about 60% - 70% but I only get around 60 - 90 fps in game usually. the frames jump around a lot too, going between 60 to 110 and back constantly. my cpu usage never goes above around 10% - 20% and memory around 30%. I ran a benchmark on userbenchmark and pretty much every piece of hardware is significantly "below expectations". cpu and gpu temps stay around 50C.
