>does it rely on any scares at all?
There's no scripted jump scares. In fact there's barely any scripted anything. All the enemies make quite quiet sounds until they start engaging so you'll strain your ears to hear them approach and always be looking over your shoulder.
Performance is okay but large open world games often have trouble when you're in a good lookout and looking at lots of things. Recent huge decrease in load times.
