it used to show my opponent few hands of hole cards played when i move mouse over hud box. its no longer there and i have not make any changes to hud. is there some setting changes i need to click to have that option again ?
Do you mean the previous hole card played in your HUD? After the latest update you will need to add the player profile icon on your HUD, drag the graph to the player icon and add net won stat to graph then save. After doing that you will see the hole card and graph the same as before.
