He might be using cutting edge PC versus your old rig, if anything.

I have a mid PC now, I just bought an Alienware Lappy to my GF, and then we see the differences, where i'm slower than her on her side, and I see myself in front of her on my Monitor.

She played on airbook MAC before, and even when sprinting, I showed her that she was walking slwoer than me on my Monitor. (please do not attempt Titan)

Could be lag, latency, your GTG Monitor response time, etc..

Or he crossbred a Chocobo that won many cups for his speed?
