So I was curious, if the PS3's RAM is like 256mn I think, and the PS4 has an 8GB RAM. So as we can see GTA V as of now looks great and we saw a tease of a trailer by good old R* but with this much RAM how much can they change? As we've seen there's nice grass, better draw distance, a good texture increase, denser population, however I was wondering if they could actually add more big or little things to the game because now the hardware can handle it, it wouldn't make sense for them not too add more little effects that makes GTA V the gem it is. Things I had in mind was the wind blowing dust around in the desert, cars being broken down on the side of the road, more random stuff everywhere.
Also I was wondering if it was possible to add PhysX to the game, I believe the PS4 can handle it so could the put it into the game this late?
