PFE is clearly a design tool addressed to novice users. It enables you to create 3D headlines in a very easy way, in fact, so easy that you could just change the default text, without tweaking any other settings, and you would already obtain quite attractive results.
Anyhow, you can change a few options (lights, shadows, zoom, lens flare, etc.) for a higher customization level. The program renders images only in JPG, allowing you to set the quality level.
In short, PFE is a pretty basic tool, but novice users will find it perfect to create titles, logos, headlines and other kinds of 3D texts.
