You have to restart the game once for the field of view to be right (‘world is warped’). vorpX adjusts the field of view automatically to fit your headset on first launch, but a restart is required to apply this change.
Hint: If you want to learn more about FOV and how vorpX handles it for different games, check the ‘Essential Hints’ guide in the vorpX help. Useful infos that save a ton of unnecessary trial and error.
As far image quality is concerned, you probably want to use a higher resolution than the default one. In case of Outlast you can pick a quality preset on the DirectVr page of the vorpX menu for that.
Hint: To get the most out of this feature, it’s highly recommended to check the ‘Custom Resolutions’ sections in the vorpX help.
