ive done everything suggested here and on steam discussions from last month
i own 2080 super i9-9000k and the game installed on ssd , so on paper its supposed to run like butter
the only thing to try is running the game on my cpu graphics (igpu) gonna edit this later after testing
edit : so i tested it , the mouse flickring reduced after 2 hours it started to flicker just a for short moment and only in party menus
as far as world map lagging , ive had none and it ran smoothly but preformence in battle is poop since am playing the last days of the third age so i would say pick your poison until taleworld and nvidia fix this -_-
