How odd. I recorded it again to see, and it came out lagless. However, part 2 of the split video was corrupted (fucking Fraps). So I recorded again. This time, both parts came out intact, but video 1 had the familiar lag. Part 2 though? Completely fine. o_O With some clever editting I think I can make this into one coherent video.
Now the question hangs "do I want to go through the headache of trying to record the rest of my IaMP lunatic 1cc?"
