=head1 pclient - Crossfire+ and Crossfire game client

Pclient is a Crossfire+ and Crossfire game client.

=head2 Features

=over 4

=item Fullscreen Map

PClient can uses a fullscreen map, which greatly enhances how much of the
game world you can see.

=item Persistent Map Cache (Crossfire+ only)

PClient can persistently cache all map data it received from the
server. This not only allows it to display an overview map, but also
ensures that once-explored areas will be available the next time you want
to explore more.

=item Hardware acceleration

Unlike most Crossfire clients, PClient take advantage of OpenGL hardware
acceleration. Most modern graphics cards have difficulties with 2D
acceleration, while 3D graphics is accelerated well.

=item No arbitrary limits

Unlike other Crossfire clients, pclient does not suffer from arbitrary
limits (like a fixed amount of face numbers). There are still limits, but
they are not arbitrarily low :)

=back

=head1 FAQ

=item The client is very sluggish and slow, what can I do about this?

Most likely, you don't have accelerated OpenGL support. Try to find a
newer driver, or a driver from your hardware vendor, that features OpenGL
support.

If this is not an option, the following Setup options reduce the load and
will likely make the client playable with sofwtare rendering (it will
still be slow, though):

=over 4

=item B<Video Mode> should be set as low as possible (e.g. 640x480)

=item Enable B<Fast & Ugly> mode

=item Disable B<Fog of War>
