When I start a walkthrough i get the following message:
"For the best walkthrough results, it is recommended that you refrain from using the computer while recording. The ESC key can be used to stop a recording early."
What does this mean?
A 3D Walkthrough is a series of picture files saved in a video format that can be played by other applications such as Windows Media Player or Quicktime. As the walkthrough progresses it has to render each frame of the walkthrough path.
This process uses a great deal of system resources. If you continue to work on the computer at the same time as the walkthrough is recording it will make the recording take longer to finish.
Since the recording process uses a large amount of computer resources and processing time, other programs on your computer may be slow until the recording is finished.
