According to reports from The Verge, the servers of the
xCloud cloud service got an upgrade for their hardware,
which now includes 8 Xbox One S devices for

not end here according to the report.
Microsoft plans in the future to move to the use of Xbox
Series X devices in those servers, which will provide a
noticeable improvement in performance, the report also
indicates that the tests for the service will start soon on
the personal computer and these tests will be done with a
resolution of 720p high definition with planning to start
testing with full accuracy 1080p soon.
