Are those the original textures? Because if so, Rockstar North deserves an extra round of applause for how good their work held up with the resolution bump. If not, they can get some applause for going to the trouble of adding a 4K texture pack, lol
all original textures, yes. All Microsoft (yes, this is done by the Xbox backwards compatibility team, not rockstar) has done is increase the resolution and apply 16x anisotropic filtering (dont ask me what that means lol, I'm not really a tech guy).
And I think you mean Rockstar San Diego, not North. Anyways, I agree, this holds up quite well.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
