Here's the short answer, right up front: no. The long, more explanatory answer is more complex of course.
Last week at E3 2014, GameTrailers host and well-known video game dude Geoff Keighley tweeted this:
After @xboxp3 interview I've been asking devs about impact of new Xbox sdk on perf. Bungie says it will get Destiny to 1080p/30fps on XB1.- Geoff Keighley (@geoffkeighley) June 10, 2014
The "Xboxp3" Twitter handle he referenced belongs to Phil Spencer, the head of Xbox at Microsoft (we interviewed him last week as well, right here), and the "new Xbox SDK" he referenced is part of the June update that the Xbox One received. In said update, developers received a new software development kit that -- according to a statement Microsoft released at the time -- "allows access to up to 10 per cent additional GPU performance." So that solves it, right? Not quite.
