Xbox 360 Backwards Compatibility Performance Improved On Xbox One Thanks To Upgraded Emulator
Microsoft's Major Nelson (Larry Hryb) stated in a Twitter post
"Tested on Banjo Nuts and Bolts, Dirt Showdown, and Fable 2. Banjo and Fable are now MUCH smoother in the areas that bogged them down before," an Xbox One user stated on Reddit. "Getting around parts of Showdown Town in Banjo was almost unplayable before, but now runs much better. Same with Fable 2. It's still not perfect, and there is the odd hitch here and there that wasn't there before, but I'll take this over the old performance any day."
One of the takeaways from this is that Microsoft is committed to improving its Xbox 360 emulator on the Xbox One. That's good new for anyone with an extensive library of supported titles, or a just a handful of titles, ones that happen to run crummy on the Xbox One.
At present, Microsoft supports over 120 Xbox 360 titles on the Xbox One, a full list of which is available online (PDF). More are being added, and as long as you own the title, you can play them for free on the Xbox One (no Xbox Live Gold subscription required).
