The differences are bigger than I thought they would be but more importantly, the absence of load times is so, so welcome and is going to make everything feel next gen, just from being able to start a game instantly. That is so, so welcome!
But being able to go from one environment to a completely different environment is also a huge boon that truly is something we couldn’t do before and that’s going to really change things up.
One of the coolest things for this is perhaps that you won’t need load-times for going in and out of buildings anymore etc without a huge sacrifice in either detail or speed.
That said, well placed use of ray tracing and jaggies being a thing of the past, if we get nice shadows too that really amounts to a very nice and convincing CGI look as well!
