Will Remote Play's performance improve over time?

Hello. The game is in game preview, which is like a beta. It means the game is constantly under improvement and is not a full release, so it most certainly will be receiving these updates to improve performance over time. So there is hope yet do not worry,
it will get better.

I cant perform a software update if i can no longer turn the comtroller on after a failure in their part. Both remotes worked perfectly fine until i tried their improved update and now both do nothing. All i can do is stare at the screen and play make believe.

You can stream your Xbox to the Xbox app on the computer using remote play. Please make sure to re-register remote play before leaving on any trip, as the keys expire over time

I don't think it will give you a performance improvement over an internal drive, if that's what you're asking.

Closing other apps while you're playing will improve performance.
