In Arx I see the file config_default.ini and the editable entries are fairly self-explanatory, although I do wonder about a couple:

forcegdi=1 ...? Force on the gdi, but is that applicable to Win7/8?
softfog=1...? rendering characteristic of the fog?
clearnearcorrection=1 ...some kind of texture junction command?
forcenoeax=0; that's easy...;)
forcemetaltwopass=1 so does this force two passes, or two passes for a specific renderer?
forcezbias=1 does this force 24-bit z, 32-bit z, ?
newcontrol=1 OK new controls...but for what? What's the "old"?
forcetoggle=0 uh, toggle what?
fg=1 ...you got me...;)
forcesoftrender=0; does this mean software rendering, or something else?

Does Arx itself harbor or allow any other kind of commands or configuration files? What about Libertatis? I couldn't find any internal config files there at all. Can one exist for the Libertatis version? (like an autoexec.config or something along those lines.)

Thanks for any insight!

Odd, but I visited the original Arx forums @ Nordic games (?) yesterday and spent quite a bit of time there sifting through posts to see if anyone had asked to have those variables explained--to my utter shock I could not find a single post asking for, or volunteering to explain, those variables as listed above!

I would have thought there'd have been a developer post somewhere about that from Arkane--but couldn't find it! Seems most perplexing why someone has not already asked for the definition of those variables. If they did ask for it--I couldn't find the post either here (gog) or there (Nordic games.) Anybody know? I would think the LIbertatis developers surely ought to know...

nb: Arx Libertatis only loads config_default.ini (form the user or data dir) if there is no cfg.ini yet - subsequent runs will only load cfg.ini from the config dir. The locations of these directories are described on the wiki. Most of these setting keys no longer exist in Arx Libertatis, meaning they were either unused or the code paths they selected have been removed/merged.

The only one remaining is This seems to enable a one-handed casting/stealth mode where the stealth/magic mode keys don't need to be held down, but instead toggle the modes when pressed.

Arx Libertatis also has a few new config keys, but all the interesting ones should have GUI controls to change them. Arx Libertatis currently only has cfg.ini, but also reads cfg_default.ini on the first run to allow overriding the built-in defaults.

AL also recognized a few command-line options: --debug is relatively useless in release builds. I'm not sure if --help/--list-dirs will be of much use on Windows, as arx.exe is compiled as a GUI application.

Thanks very much! I really like Libertatis, btw! Great!...;)
