After playing the game for 50 hours, I can definitely say the downgrade is there, but it's so fucking slight that we shouldn't give a shit. This demo definitely has a lot more effects, better physics and those fog effects are gorgeous, but should we really be so angry about this, going to the point of saying that GTA IV looks better? Because that's fucking stupid, and I'm being totally honest here when I say that if you think this looks worse than GTA IV then you're a fucking moron, plain and simple. Also, the explosion effects don't seem downgraded, more so just different. Explosions in the final game are astounding, same as in the demo, I don't think one looks better than the other, just different. The game still looks amazing on max settings on PC guys, and graphics don't make the game, they just add to it.
