Guys help me out i have a doubt on the ad supported cloud gaming feature.

i agree, i suspect that will be a feature added later (network browse). still i doubt they will add x264/mkv support so we will still need to transcode.

Hello Jamiebate113,

Thank you for posting on the Xbox forums. We began our keyboard and mouse support with very few games that support these features. We are adding this feature to more games over time with the help of the developers. The developers help by approving the feature
on their game, and updating the game's settings to modify this feature. As of this moment, we do not have any indication that
Player's Unknown Battleground will utilize this feature. The best option will be to reach out to the support team of the developer for any more information. We hope this helps!

Switch Pro is not a supported controller. There is no information when or if more will be added

Offline play depends on the developer. With the cloud component MS talked about in the reveal, they can offload work into the cloud to make the games run better. Developers have the choice to use this feature or not. If they do, you will have to be online
to play. I doubt third-parties will use it, but X1 exclusive games will down the road. In the end, it really depends on the developer.

Hello and welcome to our community!

We’re excited to have you here and have great conversations! I'd be happy to be of assistance.

I understand that you'd like to migrate your achievements from one account to another. I know this might be unexpected, but unfortunately, this feature is not currently supported.

At the moment, there's no way to transfer achievements, game progress, gamerscore, or account data between Xbox accounts. These details are tied to the original account and are stored securely via cloud storage. As long as you're connected to the internet, your progress and achievements will sync automatically to the cloud for that account.

While this feature isn't available now, I hope Microsoft considers adding it in the future based on user feedback.

Hope this information helps. Let me know if you have further questions or need clarification.
