Gaming

There can be improvements that we cant even imagine yet, but I think RT is the next Big thing and it might take some years before theres something as big. But who knows

There are many areas that can be improved upon to make games more realistic, just probably not graphical. NPCs using smarter AI, better physics, a more dynamic environment (better destruction, better NPC interaction with objects), and who knows what else that I can't think of now. There's still a lot of progress to be made, I just don't know if we'll have enough horsepower to run all of that, we're already reaching physical limitations on chips.
