You might have noticed that the Xbox One-to-PC streaming currently on offer via Windows 10...doesn't always look as good as you might have hoped. Turns out there's sometimes a reason for that. And, as luck would have it, a workaround as well.
Users are finding that in many circumstances, even when their internet+wifi speed should be fast enough, their streaming quality is being locked at "high", with the more desirable "very high" setting greyed out and inaccessible.
Reddit user OomaThurman is one of the people to have found a workaround, though, which is spelled out in greater detail in this NeoGAF thread. All it takes is the editing of an Xbox App file in Notepad. With the app closed, do this:
Step 1: Open File Explorer, and copy/paste this location:
Step 2: Scroll down and open the folder that starts with "Microsoft.XboxApp..."
Step 3: Open the folder LocalState
Step 4: Right click the file called "userconsoledata" and choose Open With.. (select Notepad)
Step 5: Change this:
into this: <IsInternalPreview>true</IsInternalPreview>
Step 6: Now open the Xbox App, begin streaming- and in the top right of the stream window, click the ((o)) button to select Very High.
And hey, whaddya know! If your bandwidth can support it, your streaming quality will be noticeably improved. Check out the slider comparison below.
