If I understand correctly, to achieve something consistent, you need a powerful system, with a video card with a lot of memory, and these cost a lot, even a lot... Or from the subjects' own accounts (which may or may not be true, but we must give them the benefit of the doubt!), they struggle with power outages and their internet is probably pathetic, and the necessary computers are harder to procure. If you add to this a family and the need to ensure your daily living, things don't seem so rosy anymore, right?!
