No, nothing correlates to Platform and connection quality.
My PC does sustain a lower ping but I guess maybe the Lag Comp is a little more aggressive on Xbox as I see it start off on 5 and it can sometimes look like it’s syncing alongside others.
But, it’s still down to the connection.
And I fully understand your frustrations, all you can do is try.
A lot of these games are in groups of 2 or 3.
This is just some examples before I got my Diamond this season.
Notice how I either equal Diamond 4/5 players and far exceed anyone else below?
That’s what it takes.
