Ok folks, no one else would have told you this lot so I'm the man, loll, here is a list of legal adjustments (Unless your on a "Pure" server) you can make to your user and 2004 ini files to optimise your gaming ease and experiance, besides I'm sick of stopping playing so I can tell you lot how to do it loll.

USER.INI

[XGame.xPawn]
bPlayOwnFootsteps=False
bUnlit=True

[UnrealGame.UnrealPawn]
bPlayOwnFootsteps=False

[JumpAnywhere.JumpAnywherePawn]
bPlayOwnFootsteps=False

[utcompv16.UTComp_xPawn]
bPlayOwnFootsteps=False <---lots of entries, you might have more of them)

[Engine.Pawn]
bNoCoronas=False

[GUI2K4.UT2k4MainPage]
TotalUnlockedCharacters=Malcolm;ClanLord;Xan

[Engine.Player]
ConfiguredInternetSpeed=15000 <...........(To increase frame rate)
ConfiguredLanSpeed=20000

Aliases[36]=(Command="fov 85",Alias="Norm")...........(Use the spare aliases you have, not necessarily these numbers)
Aliases[37]=(Command="fov 110",Alias="Mid")
Aliases[38]=(Command="fov 120",Alias="Wide")

Keybinds

?=PAUSESOUNDS........................(Will turn off music)
?=netspeed 15000........................(switch frame rate, Must be pressed to activate on every match)
?=UNPAUSESOUNDS......................(Will turn music back on)
?=mutate tossrelic...................(Throws the relic so get another one instead)
?=Norm...............................(Changes Field of view as set by aliases above)
?=Mid
?=Wide
(MiddleMouse?)?=SwitchWeapon 10 | SwitchToBestWeapon...(Used for trans, transe is weapon 10, then return to best weapon)

UT2004.INI

[Engine.GameEngine]
CacheSizeMegs=512

[Engine.Engine]
DetectedVideoMemory=512 <----Dependent on Graphics card

[UnrealGame.DeathMatch]
bColoredDMSkins=True
bAllowPlayerLights=True

[UnrealGame.DMMutator]
bBrightSkins=True

[IpDrv.TcpNetDriver]
MaxClientRate=15000 <-------Increase FPS as above
MaxInternetClientRate=15000

[Engine.LevelInfo]
MaxClientFrameRate=150.000000 <-----Increase FPS as above

[ALAudio.ALAudioSubsystem]........(Sounds from further away on map so you can hear where they are!)
Rolloff=0.400000

Please note you can set a switch so one button does two things "?=PAUSESOUNDS | netspeed 15000" is for, stopping the music and changing your fps at the same time

The netspeed stuff is to increase your frames per second, by default it is 90, but can be changed with the above numbers to 150, actually on my rig I can get 600 by setting 60000, but there is no point above 150, how much more smooth can you notice a difference on? Remember you have to press the button on every game!

The ALAudio is for hearing sounds at a distance, the lower the number the further away you can hear.

The Aliases are just quick ways to change your field of view on the fly, the bigger the number the more "Fish eye" the FOV

Also if you've not got a cache (Map) extracter,

[Editor.EditorEngine]
CacheSizeMegs=64

[Core.System]
PurgeCacheDays=999 or "0" will never delete cache (Better to get a "Cache" extracter though, you can play maps offline then, also see the picture of a map on map vote if uncached)
