Using the SkyrimPrefs.ini File
You can also disable quest markers by using the SkyrimPrefs.ini file which is located in the Documents\My Games\Skyrim\ folder. As always, before making any changes to any .ini file, make a backup and save it in a safe place in case you screw something up and want to return to default settings.
You will be looking for the following section:
[GamePlay]
bShowFloatingQuestMarkers=1
bShowQuestMarkers=1
Just set one or both of these settings to 0 and save the file:
[GamePlay]
bShowFloatingQuestMarkers=0
bShowQuestMarkers=0
The next time you load up Skryim the floating quest markers and/or quest markers will be gone.
You only need to change the SkyrimPrefs.ini file once and it will remember the changes every time you play.
Note that when you use the SkyrimPrefs.ini file, you won't be able to activate the markers in-game using the Journal. You will have to exit, re-edit the file and re-start the game. This can be a good way to avoid temptation if you want to play without the markers but can't resist the urge to turn them on now and then while playing.
Et pour supprimer le voyage rapide :
Skyrim doesn't give you an option to disable fast travel in the Settings menu, but it is easily done with a simple console command.
To disable fast travel, open the console by pressing the tilde key '~' and type the following:
enablefasttravel 0
Hit enter and press the ~ key to exit the console. The fast travel setting will be saved along with your game.
If you change your mind and decide that you want fast travel back, just open up the console again and type:
enablefasttravel 1
Hit enter, ~, and save.
