Recording lag

[Bridge]

I seem to be getting some choppy video even though the FPS counter on Bandicam indicates the video is recording at a steady 60fps. I'm trying this out on Mirror's Edge as it's the only game I have installed at the moment. Here are my specs:

MB: Gigabyte H77-DS3H
CPU: Intel i5 quad core ~3.5GHz
RAM: 8gb
GPU: AMD Radeon HD 7800 -400MHz -1749mb
DX11
120gb SDD
OS: Windows 7 64bit
~20" LCD screen 1680x1050

I encounter no slowdowns while recording but the video tends to lag slightly (enough so that it's noticeable). With Fraps I get an unbearable framerate (10fps). The most common advice I found online to reduce lag was to record to another HD than the one the OS runs off of but since it's a solid state with a huge RW speed (500mb/s) I don't see how it matters. It should be more than enough to record game footage I imagine. What do you guys think? Is my computer just not cut out for recording or is there a way to significantly decrease recording lag? Here are some short samples:

Could anybody maybe recommend some other process-light recording programs that can record HD footage? I have Bandicam on the highest video settings and it's hardly what I would call HD.

Thanks in advance.

EDIT: Watch them in full screen; the lag is not noticeable in the embedded youtube player.
