-insecureWindows OnlyDisable Valve Anti-Cheat (VAC) system.
-lowmemoryAllLaunch options that reduces graphics and audio effects to save about 800 MB RAM, likely enabling 4GB RAM players to get past infinite-loading screens
-MapModID=#########AllDedicated servers can now optionally load custom maps via ModID diectly, rather than having to specify the map name directly, using this syntax (where the MapModID is the Steam Workshop FileID of your custom map, and the GameModIds are the Id’s of the stacked mods you wish to use, in order) Introduced in patch 193.0

-nofishlootAlldisable non-meat Fish Loot when using Fishing RodIntroduced in patch 245.9
-noninlinesaveloadAllFixed a savegame corruption case with large savegames: this is experimental, so try with this command, if you have any saves that don’t load. We’ll formally roll this loader change out in a subsequent patch after we’re 100% certain it has no side effects.
-nomanskyAllLots of detailed sky features are disabled, such as clouds and starry night sky. This decreases all of those but you can still have them. You still obtain the stars, the sun, and the moon. This just helps you remove the sparkling stars that make you sightless at night
-nomemorybias-Reduced client game memory usage by about 600 MB system and 600 MB GPU RAM! (all meshes now stream LOD's dynamically). This could potentially have a small runtime performance impact, so to use the old method (more RAM usage but no potential performance loss), launch with -nomemorybias
?NonPermanentDiseases=true-This will make Diseases not permanent (you will then lose them if you respawn).
?OnlyAutoDestroyCoreStructures=true-You can launch an autodestroy enabled server with this option to prevent any non-core/non-foundation structures from autodestroying (however they'll still get autodestroyed if a floor that they're on gets autodestroyed, of course).

?PreventUploadDinos=False-Prevent Cross-ARK Data Transfer Introduced in patch 246.0
-PreventHibernation-In both Single Player and Non-Dedicated Servers creatures in inactive zones are in hibernation instead of in stasis. Use this option to prevent hibernation at the cost of performance and memory usage. Introduced in patch 259.0
?PreventOfflinePvP=true-Use this to enable the offline raiding prevention option.
?PreventOfflinePvPInterval=900-That would be a 15 min wait before a tribe/players dinos/structures become invulnerable/inactive after they log off. (if Tribe, requires ALL Tribe members logged off!)
?PreventSpawnAnimations=false-Setting to true lets player characters (re)spawn without the wake up animation. Introduced in patch 261.0

?ShowFloatingDamageText=true-Use this to enable RPG-style popup text stat mode.
?ServerAdminPassword=passwort-If specified, players must provide this password (via the in-game console) to gain access to administrator commands on the server. Also used to log in via RCON.
-servergamelogAllEnable Server Admin Logs (including RCON support) use RCON command “getgamelog” to print 100 entries at a time also outputs to dated file in in “\Logs”, adjust max length of RCON buffer with commandline: “?RCONServerGameLogBuffer=600” Introduced in patch 224.0
-sm4Windows Only?-
-StasisKeepControllers-AI Controllers to once again be destroyed on Stasis, too much memory overhead to keeping them around on large maps. For servers with a lot of RAM, they can now optionally gain performance by running with this to keep the AI's in memory.
-StructureDestructionTag=DestroySwampSnowStructuresAllOne-Time Auto-Structure Demolish on Swamp and Snow Zones: To do this, which you can only execute once after updating to v216, run your server or game with this commandline
?TheMaxStructuresInRange=10500-new value for maximum allowed structures on a server. replaced NewMaxStructuresInRange Introduced in patch 252.1
?TribeLogDestroyedEnemyStructures=true-By default enemy structure destruction (for the victim tribe) is not displayed in the tribe Logs, set this to true to enable it. Introduced in patch 247.93
-USEALLAVAILABLECORESAllAll of your CPU cores will be used, if all of them are not being utilized after using this launch option, then try to disable it!

After the first & second times that you start the game & load will be still be slow, but the third time onwards will be fast. This may be deprecated, as of 188.2 as it was added, by default, for the PrimalData. It was also supposed to be added to all maps, but has never been clarified as to if this occurred.
?UseOptimizedHarvestingHealth=true-"optimized" server with high HarvestAmountMultiplier (but less rare items).
?bRawSockets?Direct UDP socket connections rather than Steam P2P, for significantly increased server network performance. Need to manually open ports 7777 & 7778 if you do so in order for your server to accept connections. Introduced in patch 213.0
-nonetthreading-option for bRawSockets servers to only utilize a single thread for networking (useful to improve performance for machines with more servers than cpu cores, on Linux in particular) Introduced in patch 271.15 seems to be deprecated with patch 271.17
-forcenetthreading-Defaulted dedicated server ?bRawSockets mode to not use threaded networking, seemed to generally be a net performance loss in our analysis. Use this to forcefully enable it.
-vdayAllActivate Valentine’s Day Event (2x Mateboost Range, 3x Mating Speed/Mating Recovery, 3x Baby/Egg Maturation Speed, 1/3rd Baby Food Consumption). Possibly deprecated; use -ActiveEvent=vday instead.

-exclusivejoinAllActivate a whitelist only mode on the server that only lets players join if added to the allow list. Not to be confused with "Admin Whitelisting" which uses "AllowedCheaterSteamIDs.txt" to allow players to cheat. This option uses "PlayersJoinNoCheckList.txt" to allow people to join but not give them cheats. If the file does not exist in your Linux/Win64 Binaries folder, create it and add the Steam64 IDs of the players you wish to be allowed to join your server. Path; "\ShooterGame\Binaries\Win64" "/ShooterGame/Binaries/Linux/". You will need to restart your server, if you add new lines to the file while it is running. You can however use "Cheat AllowPlayerToJoinNoCheck 12345678901234567" in game, to add a new player to the whitelist. This method will also save to the file, so you don't need to reboot the server.
-ActiveEvent=PCenables a specified event Only one can be specified and active at a time event name Description Easter Allows for the Easter Event to be activated Arkaeology Allows for the Arkaeology Event to be activated. ExtinctionChronicles Allows for the Extinction Chronicles Event to be activated.

?ServerCrosshair=false-Use this to disable the Crosshair on your Server Introduced in patch 245.0
