I would like to display my time played, global or per game. Is it possible? If not, can You ...

On the Xbox One you can see how much time you've spent on a specific game compared with someone else on your friend's list. However, that feature is not available for the Xbox 360.

It is a good idea though. You should post it in the Feedback Forums to see if it can be added.

Hey there - if OneCast works anything like the Windows 10 Streaming app, then this wouldn't be possible. The Xbox can only stream one person playing at a time - essentially, OneCast/Streaming just takes the images the Xbox would normally display and shows
them elsewhere, it's not done on a per-account basis.

[quote user="VLT034 Violynne"]Want to bet 1080i looks worse than 720p? It does![/quote]Depends on what sort of game you are playing.

720p is better for displaying quicker scenes due to being able to display frames per second better. 1080i however would be better for slower paced games where you are likely to linger for a greater time on an image

When I enquired about this with official support earlier today because I also was wondering if this feature existed like on the 360, to my surprise I was told that currently there is no global setting you can change to switch controller vibration completely
off on the xbox one. It seems as though it is being done on a per game basis meaning you have to hope that devs decided to add it as an option in their games settings so you can actually have it off.

Hopefully it will be added back in as a global setting in a future update so you don't have to set it for every game you play.

Ok... so the maximum frame rate of the game is 60 frames per second. That's 60Hz. With 120Hz the display will render you the same frame twice per second. How does it make the picture any better? Response time of the display would be a more critical number
to look at.
