I do not use an artwork, the lag is there, believe me, maybe you just got used to it. Test it with a high speed camera and an led. I use canon v1 in 1200fps and an arduino board which pushes keyboard events with just a 1ms latency. I can measure the lag with 1ms accuracy, so I know what I'm talking about.
