Can’t help ya I am afraid I have not played on PUBG for two weeks so I do not know if the patch improved things or not. I have not been following things to be updated.
I suggested trying the North American servers as these played “okay” before full release. I suspect the “lag” will still be there - as for region hop? don’t know what that means. This game has always allowed you to pit your skills against different time zone players.
