AVSIM Hardware Forums Moderator Paul Johnson has put together the AVSIM Software and Hardware Guide for both the DX9 and DX10 versions of FSX. It incorporates the latest and best techniques and the tried and true standbys into detailed instructions on what to do and how to do it. Paul will periodically update the guide as needed on a regular basis as new information, equipment and methods evolve. We hope that you will benefit from the accumulated wealth of knowledge presented here.
