Two questions

[impp]

So I witness a speed hacker what do I do? I am certain is was hacking as he chased me down, I hid behind a tree and camoed he instantly speed off and kept accelerating to a speed much faster than a horse. He was out of sight in about two seconds and I was running after him.

Presumably video is required so how to do I go about getting my system set up to do this without using up all system resources? (I have a couple of screen shots but they don't really convey the speed so much).

Thanks
