     inline (vector) graphics, such as LaTeX-picture, PSTricks or pgf/TikZ
     generated pictures, or just from typeset text.
 
+    The `animate' package relies on Optional Content Groups (OCG), also known as
+    PDF layers, which is a feature provided by the PDF-1.5 specification. Each
+    frame of an animation is associated with an OCG that is hidden or made
+    visible in a dynamic fashion by means of Adobe Reader's built-in JavaScript
+    engine.
+
     It supports the usual PDF making workflows, i. e.  pdfLaTeX and LaTeX ->
     dvips -> ps2pdf (Ghostscript).
 
     The resulting PDF can be viewed in current Adobe Readers on all supported
     platforms.
 
-    The first release of `animate' was based on the work by Jan Holecek and Petr
-    Sojka:
-
-           http://www.fi.muni.cz/~xholecek/tex/pdfanim.xhtml
-
-    Meanwhile, the package was rewritten to use Optional Content Groups (OCG),
-    aka PDF-Layers. OCG-based animations are fully supported by Adobe Reader 8,
-    but have some performance issues. Playback is usually slower in Reader 8
-    than in previous versions, which is probably a bug.
-
-    The old, non-OCG approach is still available if the package file
-    `animate-noocg.sty' is used instead of `animate.sty'. However, options
-    `autoplay', `autopause' and `autoresume' are not functional in Reader 8.
-    Moreover, the animation position and the play/pause buttons are not properly
-    reset on page change. This is due to usage restrictions that Adobe imposed
-    on some important JavaScript methods in Reader 8.
-
     Note, this file only gives a summary of usage and available package and
     command options. Please refer to the documentation `animate.pdf' in the
     `doc/' directory for details and examples.

 \section{Bugs}\label{sect:bugs}
 \begin{itemize}
+  \item The maximum frame rate that can actually be achieved largely depends on the complexity of the graphics and on the available hardware. Starting with version 8, Adobe Reader appears to be somewhat slower. However, you might want to experiment with the graphical hardware acceleration feature that was introduced in Reader 8. Go to menu `Edit' $\rightarrow$ `Preferences' $\rightarrow$ `Page Display' $\rightarrow$ `Rendering' to see whether hardware acceleration is available. A 2D GPU acceleration check box will be visible if a supported video card has been detected.
+
+  \item The Adobe Reader setting `Use page cache' (menu `Edit' $\rightarrow$ `Preferences' $\rightarrow$ `Startup') should be \emph{dis}abled for versions 6 \& 7, while remaining \emph{en}abled beginning with version 8 (menu `Edit' $\rightarrow$ `Preferences' $\rightarrow$ `Page Display' $\rightarrow$ `Rendering').
+
+  \item The \verb+dvips+ option `\verb+-Ppdf+' should be avoided entirely or followed by something like `\verb+-X 2400 -Y 2400+' on the command line in order to set a sensible DVI resolution. In times of Type-1 fonts, this does \emph{not} degrade the output quality! The configuration file `config.pdf' loaded by option `\verb+-Ppdf+' specifies an excessively high DVI resolution that will be passed on to the final PDF. Eventually, Adobe Reader gets confused and will not display the frames within the animation widget.
+
+  \item Animations do not work if the PDF has been produced with Ghostscript versions older than 8.31. This applies to all versions of ESP Ghostscript that comes with many Linux distributions.
+
   \item The command {\tt\string\multido} and its relatives from package `multido' do not work if the loop body contains {\tt\string\newframe}. Use {\tt\string\whiledo} from package `if\/then' instead. (There is no need to load `if\/then' explicitly; it has already been loaded by `animate'.) A counter must be declared to keep track of the number of iterations. Further variables that take fixed point decimals to be used within the loop body can be defined and incremented by means of the commands \verb+\FPset+ and \verb+\FPeval+ from package `{\tt fp}'.
