Las Vegas, NV
I'm about 12hrs in so far. I'm pretty much killing everything in sight, but doing it with stealth. I guess you can play through the whole game without killing a single person if you wanted.
This game absolutely runs amazing.
It's weird, my GPU is running at only 40-50% usage and a nice cool 50c with the fans barely making a peep.
I don't know if the game is just that well optimized or what.
