Parameter	Effects
-best
-cleansaves	Deletes all save files upon starting the game.
-debug
-debugcomplete
-dualmouse
-flags
-fpslock	Locks the game's framerate to the monitor's refresh rate when running in a window. By default the game runs uncapped in windowed mode, and locks automatically in fullscreen.
-ftm	"Force texture management". The game's readme file claims this option "makes you [sic] videocard use all available texture memory". This option is used by the Voodoo2 option in the game's Video Card selector program (CLGen)
-fvf	"Force vertex fog". Forces a vertex-based distance fog in first-person views. By default LEGO Rock Raiders attempts to use table-based fog; however this does not work on some graphics cards (due to both lack of support in older cards and poor compatibility with Rock Raiders in newer ones). This option is used by the Savage3D option in the game's Video Card selector program (CLGen) No fog; the world cuts off suddenly at the draw distance Vertex fog forced using -fvf Table fog on a supported video card (emulated with dgVoodoo) Further reading on table fog (or pixel fog) and vertex fog: Rogers, Douglas (January 10, 2000).

-insistOnCD	Stops the game from launching unless a LEGO Rock Raiders CD is inserted into the first lettered disc drive in the computer (searches for CDROM:\Data\cd.key). Due to a bug, this parameter prevents the game from starting at all. A no CD error message
-nm	??? Incorrectly listed as -nom in the game's readme file.
-nosound	Disables all sound, including music, but excluding FMV sequence audio.
-programmer
-reduceanimation	Disables the rockfall animation that plays when changing screens in the main menu. (This animation is disabled by default in the German version.)
-reduceflics	Disables all FLIC animations, such as the random animations on the game's main menu and Chief's animation on the mission scoring screen.
-reduceimages
-reducepromeshes	Reduces the number of level of detail (LOD) meshes for objects and surfaces in first-person mode. For objects, this only affects parts listed with a ! prefix in the object's AE file. For instance, in the Rock Raider (Pilot) AE file, only parts in the HighPoly {} block uses the ! prefix (eg, !vlphead   hphead), so these will be disabled while parts listed in MediumPoly {} and FPPoly {} will not be. For wall and floor meshes, this functions the same as setting Wall Detail to Low in Advanced Options. A first-person view with -reducepromeshes disabled The same view with -reducepromeshes enabled The Rock Raider's HighPoly {} models are not loaded with -reducepromeshes enabled, while its MediumPoly {} models are The controlled Rock Raider's head, visible in "shoulder view", still uses the model defined in the AE file
-reducesamples
-showversion	Displays the game's version number (V.0.121) in the bottom-right corner of the screen while on the main menu, the load/save screen, the level select screens, and the pause/options menu.
-startlevel
-testercall	Identical functionality to -testlevels. Intended to sound like "testicle"; programmer and level designer Karl White, who added this parameter, said in 2010 that it "was never, ever, ever meant to see the light of day."
-testlevels	Unlocks all levels regardless of completion status. Games saved while this parameter is active will return to default unlock behaviour if loaded while it is disabled.
