I'm sure there's plenty of documentation but in addition to that ensure you do the following:
1. Defrag your hard disk(s). Make sure there's loads of free space, particularly on the disk where your Dazzle temp files will be created
2. Update your virus checker & then disconnect from the Internet
3. Disable screensavers, power saving, virus checkers, firewalls, P2P, ad-blockers, disk utilities, instant messaging etc. i.e. everything
So ensure that the only icons that appear in the bottom right-hand corner are, at most, for Power Source, Display, Safely Remove Hardware (for laptops), Volume, Disabled Virus Checker.
