Also on a more general question. Once I import a game setting, it should already optimize the game according to that specific profile or do I have to set that profile through selecting the game in Optimize Game Settings.
If that’s the case how can I use a user’s Alien:Isolation profile?
There isn’t an Optimizer entry for Alien Isolation, sorry.
Game profiles and the Optimizer are two different things. While profiles store the settings that vorpX uses while running, the Optimizer changes the actual .ini/registry etc. setting of a game. If there is an Optimizer entry for a game, you need to apply that additionally to importing/loading a profile.
