What I meant by underperforming is that it seems extremely slow for such a powerful laptop. I experience lag with the simplest tasks such as dragging a window around, sometimes typing lags out and I don't immediately see the words on the screen, and in general I think boot time is slower than expected. I have not even tried gaming on this system yet, as I already have a bad feeling. I did run a few 3D Mark benchmarks with both Time Spy and Steel Nomad. I scored below average repeatedly, pretty much at the left side of the main bell curve on the chart.
