I upgraded to this yesterday (along with the new manager)... I made no changes to my config or new options and found that playing PUBG that after everytime I jump from the plane my keyboard inputs do not work for about 3-5 seconds.... I also noticed something similar when getting into a game lobby where my mouse input works, but the keyboard is delayed in working for a few seconds....
After polling some questions on these forums about these new options and their use with PUBG, the resounding response was they are not needed or have any affect with PUBG, so I'm going back to the old 501/528 as even if these new issues had nothing to do with this new 1019 there's no use for me to be on 1019.....
