you are not wrong but this is merely a demonstration of what they are looking to achieve, and honestly more an early look at the power difference between the Pro and PS5.
As long as we see a reduction in loading time from this gen (even if not on the scale shown in the video), that it an improvement I think we will all gladly welcome.
It's still kinda lame what they do. Holding back progress on purpose and then trying to wow people with old tech and mediocrity.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
