Nah, for me it was about the storms part, that sounds cool. I don't have a Pro but I'm sure Rockstar will have taken well advantage of the hardware, just like they did with One X for RDR2.
I'm really hoping and expecting that this game world is going to be amazing, it has to. Maybe a rather odd example but I recently played Goat Simulator 3 with my nephew and I was surprised how detailed actually that game world is.
Considering the game, I didn't expect that. Plenty of stores you can enter and have detailed interiors, festivals and markets, I saw people having a picknick and just general NPCs doing specific things in certain areas.
When I see this I can only imagine what Rockstar has managed to put in this game to have a lively and realistic world with the insane budget this has.
