Greenberg is a fucking joke. Good lord.
In his defense, Greenberg is the one guy managing to pull a worthwhile frame rate out of the system at a native 1080p.
Admittedly,90 percent of Forza 5 is static, baked in environments though, so it's not as impressive as they would like people to believe.
But meanwhile, Double Helix can't even get a downloadable fighting game to run on the thing at 1080.
