I play normal tables at stars, and hud is not shoving results regularly. I have to minimize table window and bring it back up to show up to date stats. It is alw on 1 table only. Didn't notice it lagging on other tables (I play 3-4 tables)
I have the latest official version of HM2, and when I updated to the newest beta updated it was the same.
EDIT; and it is alw the table opened last.
