-\fBVideoPriority\fP set to 1 gives the same priority both to video and to
-other pixels.  Higher values give more priority to video.  For example, the
-value 5 specifies that the rate of sending video will be five times higher

+.B DeferUpdate
+x0vncserver uses a "deferred update" mechanism which enhances performance in
+many cases. After any change to the framebuffer, x0vncserver waits for this
+number of milliseconds (default 1) before sending an update to any waiting
+clients. This means that more changes tend to get coalesced together in a
+single update. Setting it to 0 results in the same behaviour as earlier
+versions of x0vncserver, where the first change to the framebuffer causes an
+immediate update to any waiting clients.
