12 arx is the main executable of Arx Libertatis, a cross-platform port of
13 the first-person role-playing game Arx Fatalis. You will need the data
14 from the original Arx Fatalis to run the game. See https://arx.vg/data
15 for where you can get it.

18 Here is a short summary of the options available in arx. Please refer
19 to the detailed documentation below for a complete description.
20 Generic options:
22 -h --help Show supported options
23 -g --debug LEVELS Set debug output levels
24 --benchmark[=TIMELIMIT] Log loading times and framerates
25 --debug-gl[=MODE] Enable OpenGL debug output
26 --override-gl OVERRIDES Override OpenGL extensions
27 Search path options:
29 -n --no-data-dir Don't automatically detect data directories
30 -d --data-dir DIR Where to find the data files (can be repeated)
31 -u --user-dir DIR Where to store user-specific files
32 -c --config-dir DIR Where to store config files
33 -l --list-dirs List the searched user and data directories
34 Startup options:
36 --loadlevel LEVELID Load a specific level
37 --loadsave SAVEFILE Load a specific savegame file
38 --loadslot SAVESLOT Load a specific savegame slot
39 --skiplogo Skip logos at startup
40
42 --benchmark[=TIMELIMIT]
43 Log time taken for startup, loading levels and shutdown, and the
44 minimum, maximum and average framerate.
45 If a TIMELIMIT argument is given, the game will exit after the
47 specified amout of time has been spent rendering normal frames.
48 This time does not include the startup or loading time. Valid
49 values are a number, optionally followed by a unit. Valid units
50 are "ms" (milliseconds), "s" (seconds), "m" (minutes) and "h"
51 (hours). The default unit is milliseconds.
52 This option can be combined with the --loadlevel, --loadsave or
54 --loadslot options to benchmark a specific scene.
55 -c, --config-dir=DIR
57 By default arx will store configuration files in directories
58 specified by the XDG Base Directory Specification. This option
59 overrides the directory where config files are loaded from and
60 saved to.
61 -d, --data-dir=DIR
63 Arx Libertatis will look for data files in directories specified
64 by the XDG Base Directory Specification and in the directory
65 containing the game executable. Besides the system-wide data di‐
66 rectory, data files are also loaded from the user directory,
67 which can be set by the --user-dir option.
68 This option adds additional directories to search for data files
70 before the detected system-wide directories, but after the user
71 directory. To override the detected data directories combine it
72 with the --no-data-dir option.
73 The --data-dir option can be repeated to add multiple data di‐
75 rectories, in which case they are searched in the order pro‐
76 vided.
77 See https://arx.vg/paths and the --list-dirs output for more de‐
79 tails.
80 Use arx-install-data(1) to extract and install the required data
82 files from the various different Arx Fatalis setup executables,
83 archives, CDROMs and existing installs.
84 -g, --debug=LEVELS
86 This option can be used to enable debug output for debug builds
87 of Arx Libertatis. For non-debug build, this option is not very
88 useful but recognized for convenience.
89 --debug-gl[=MODE]
91 Control OpenGL context type and debug output from the OpenGL
92 driver.
93 The following modes are possible:
95 "enabled" Enable additional error checks in the OpenGL driver
98 and log all reported errors. This is the mode used when
99 --debug-gl is specified with no MODE argument.
100 "ignored" Enable only the standard OpenGL error checks required
102 by the standard and ignore all errors.
103 "noerror" Tell the OpenGL driver to assume that there will be no
105 errors. Will fall back to "ignored" if not supported.
106 "default" Select one of the above modes depending on the build
108 type and enabled features. This is the default when --de‐
109 bug-gl is not used.
110 -h, --help
112 Show a list of the supported options.
113 -l, --list-dirs
115 Show the data, user and config search directories and how they
116 were determined. To adjust the search directories, use the
117 --no-data-dir, --data-dir, --user-dir and --config-dir options.
118 --loadlevel=LEVELID
120 Load a level immediately after startup, without displaying logos
121 or the main menu. LEVELID is the number of the level to be
122 loaded.
123 --loadsave=SAVEFILE
125 Load a save file immediately after startup, without displaying
126 logos or the main menu. SAVEFILE is the path of the save direc‐
127 tory or .sav file to be loaded.
128 --loadslot=SAVESLOT
130 Load a save file immediately after startup, without displaying
131 logos or the main menu. SAVESLOT is the index of the save slot
132 to be loaded.
133 -n, --no-data-dir
135 Disables looking for default data directories. Default user and
136 config directories and data directories provided using the
137 --data-dir option are still searched. This option can be used
138 for portable setups where user, config and data files are all in
139 the current directory:
140 arx --no-data-dir --user-dir=. --config-dir=.
142 --override-gl=OVERRIDES
144 Overrides the used OpenGL extensions and features. By default,
145 Arx Libertatis will use all extensions that the driver claims to
146 support except for some that are known to cause issues with cer‐
147 tain drivers. This options allows the user to disable additional
148 extensions or re-enable extensions that are by default disabled.
149 It will not make Arx Libertatis attempt to use extensions that
150 the driver does not claim to support.
151 The overrides passed to this option are parsed after, and thus
153 overrride, those in the extension_override setting in the
154 [video] section of cfg.ini which is in turn applied after the
155 built-in driver quirk overrides.
156 All disabled extensions - either by built-in rules or user-sup‐
158 plied overrides are logged.
159 The override string is made up of a series of override tokens
161 separated by whitespace. Supported overrides are:
162 "-GL_ext": Disable OpenGL extension GL_ext.
164 "+GL_ext": Re-enable OpenGL extension GL_ext if it was disabled
166 by a previous token (including built-in driver quirk
167 rules).
168 "GLx.y", "x.y", "GLxy" or "xy": Re-enable extensions part of
170 OpenGL version x.y and disabling all others
171 "GLx" or "x": Re-enable extensions part of OpenGL version x.0
173 and disabling all others
174 "+*" or "+": Re-enable all non-core OpenGL extensions
176 "-*" or "-" Re-enable extensions part of any known OpenGL ver‐
178 sion and disabling all others
179 Note that the version overrrides (i.e. all except "-GL_ext" and
181 "+GL_ext") fully override the set of allowed extensions and thus
182 make all previous tokens meaningless. In particular, --over‐
183 ride-gl="+" will disable both the built-in driver quirk over‐
184 rides and the extension_override setting while --over‐
185 ride-gl="1.5" will disable the use of all optional extensions.
186 --skiplogo
188 Don't display Logo images at startup. Currently this will not
189 skip the intro cutscene.
190 -u, --user-dir=DIR
192 By default arx will store user files (saves, etc.) in directo‐
193 ries specified by the XDG Base Directory Specification. This
194 option overrides the directory where user files are loaded from
195 and saved to.
196 Configuration files are not stored in the user directory, but in
198 a separate directory that can be set by the --user-dir option.
199 The user directory will also be used to load data, overwriting
201 resources from the system-wide data directories amd from direc‐
202 tories specified by the --data-dir option.
