STAT ACTOR - STAT CACHE - STAT CLIP - STAT FILTER
Shows various statistics.
STAT FPS - STAT GAME
Show frame time in milliseconds
STAT GLOBAL - STAT HARDWARE - STAT ILLUM -STAT LIGHT - STAT MESH
Shows useful performance timings in milliseconds
STAT NET - STAT POLYC - STAT POLYV
STAT REJECT - STAT OCCLUSION
STAT SOFT - STAT SPAN - STAT ZONE
Show network performance statistics including ping, packet loss, bytes/second. DEBUG CRASH Test crashing the game by appError.

DEBUG EATMEM Test allocating memory until it fills up.
DEBUG GPF Test a general protection fault.

DEBUG RECURSE Test crash by infinite recursion.

DUMPCACHE Display the contents of the memory cache GCache.

DUMPNATIVES Display a list of unused native function ids.

EDITACTOR CLASS=classname During game play, edits the properties of the nearest actor belonging to that class. Cool for debugging.

GET (classname) (variable) Gets the default value for a variable in a class

MARK Mark all objects that are in memory (for garbage collection debugging in conjunction with MARKCHECK).

MARKCHECK Display a list of all unmarked objects that are in memory (for garbage collection debugging in conjunction with MARK).

MEM List memory usage; only works when Unreal is compiled with the memory-tracking option (it's usually not).

MEMSTAT Show Windows overall memory statistics.

OBJ CLASSES Prints a list of all loaded classes.

OBJ DEPENDENCIES PACKAGE=pkgname EXCLUDE1=otherpackage EXCLUDE2=otherpackage... Show package dependencies

OBJ GARBAGE Collect and purge garbage ("garbage" means objects which are no longer in use).

OBJ HASH Show object hashing statistics.

OBJ LINKERS Show a list of active linkers (each linker is responsible for loading objects from a package file).

OBJ LIST CLASS=objectclass INSIDE=insideclass List all objects belonging to the class and residing inside the specified object. If the class isn't specified, lists ALL objects. If the inside object isn't specified, shows all objects. Gives a summary of memory usage. This is very useful during game play for figuring out how much memory is being used. In UnrealEd, this statistic isn't useful because a huge amount of extra stuff is loaded which might not be used by your map.

OBJ REFS CLASS=objectclass NAME=objectname Show a list of objects which reference the object you specify. When trimming memory usage, this is useful for figuring out why some object is being loaded.

REPORT Copies a report of the current gameplay situation to the clipboard. You can then paste the resulting text into an email program, Notepad, etc. Extremely useful for beta testers, because it dumps the player's X,Y,Z location, the difficulty level, etc.

RMODE Set the rendering mode. 0-9

SET (class) (variable) (value) Sets the specified property of the specified class with the specified value

SHOWACTORS Shows actors during gameplay.

SOCKETS In network play, shows a list of network sockets (UNetConnection's) in use.

URL urlname In network play, parses a URL and displays its components.
