Bonjour,
Petite astuce pour avoir une qualité graphique bien supérieure aux possibilités actuelles.
1. Télécharger Notepad++: http://notepad-plus-plus.org/fr/ et installez le.
2. Allez dans le dossier d'installation (ici de steam) par ce chemin d'accès: C:\Program Files (x86)\Valve\Steam\SteamApps\common\Alien Isolation\DATA
Vous y trouverez un fichier nommé "ENGINE_SETTINGS" en XML
3. Cliquez droit dessus et ouvrez le avec Notepad ++ fraichement installé, supprimez le contenu et remplacez le par ce qui suis:
<?xml version="1.0" encoding="us-ascii" standalone="yes"?>
<!-- Defines the hierarchical settings exposed by the engine -->
