I'll always take game play over graphics. The AC, guns, damage model, aircraft variety all trump scenery. But that just my opinion.
But those pics do look really REALLY good. I like the clouds, the scratches, the raindrops, the vapor trails. I can imagine my frame rate at reduced to frames per minute rather than frames per second with stuff like that. lol So, after the install, I'd fly a sortie or two with all that stuff turned on. "Ohh Ahh", for a minute. Then turn it all off, and go back to fighting cons.
<S> To all you guys with the machines that can keep up with today's graphics.
