Full Screen Experience issue on Rog Xbox Ally X

You should not be running anything at 120hz on a portable device. Your battery will make a flood look tame how fast it empties. I'm sure some games will but it's not a good idea

This is a Windows handheld, and it plays windows games, and only PlayAnywhere games would be playable from your Xbox library

at this time there is no indication that would happen

you could play them through cloud gaming, but these games cannot function natively on a PC which is what this is.

While Xbox shares many of the same technologies, it contains strong digital rights management, as well as a custom architecture that is not compatible with the PC

Thank you for following up, I am having the same issues on my ROG ALLY. I appreciate it so much

It still doesn't work. On my rog ally it doesn't update and it stay on updating with 0% progress

I had the syncing thing when I was playing Starfield on my Xbox and ROG Ally, weirdly it was always when going from my Ally to my Xbox, not the other way around.

I eventually worked out what the issue was, I was switching off the Ally as soon as I stopped playing. What's I should have done was leave the Ally on for half an hour or so while it uploaded the save file to the cloud..

Perhaps that's the issue with you, the game knows there is an updated file, but cant access it because it wasn't uploaded fully. Perhaps turn on your old PC and let the save file upload.
