Fixes & Updates in 1.3:
============================
- PunkBuster(TM) support has been added.
- EAX(R) ADVANCED HD(TM) support in the sound engine contributed by Creative
Labs(R). Doom 3 base game comes with room reverb data.
- To utilize EAX(R) ADVANCED HD(TM) in Doom 3, you must have 100% EAX 4.0
compatible sound card. Please refer to your sound card manufacturer for
details on whether or not your sound card supports EAX 4.0.
- Sound Blaster(R) Audigy(R) 2 users who wish to utilize the new EAX 4.0
feature in Doom 3 should download the latest Creative Beta Drivers for the
card released on April 5th, 2005. Not using these drivers may result in game
instability while using EAX 4.0.
- Server provides .pk4 file download URLs (http/ftp), client has internal
download.
- New class of .pk4 files: 'addon paks' are only referenced when the map is
loaded in.
- .pk4 downloads and addon paks come with a number of fixes to the 'pure
server mode' filesystem code.
- Fixed ragdoll bounciness.
- Fixed how Doom 3 detects LAN client vs. Internet clients.
- LZW compression of render demos.
- Fixed command line parameter passing.
- Added a QuakeIII-style graph of the connection quality for network clients
controlled with net_clientLagOMeter cvar
displays a graph of how much the client predicts ahead of the server
note that you can change the minimum predict ahead of a client by
setting net_clientPrediction

Changes relevant to mod developers (SDK):

- Added UploadImage to idRenderSystem interface. This lets the user blit
images to the renderer.
- Supports fs_game_base; this lets you base a mod off base game + d3xp +
your own content.
- Most of the download redirection is handled in the game code, and can be
extended.

Linux specific:

- ALSA device opened non-blocking to avoid hangs.
