Very bad perfomance

Im playing on a rx 6700 xt and i5 13k processor on 2k resolution with all the settings turned to lowest (i usually play 1920x1440 but i cant play marathon without black bars with that rez so i play 2304x1440) and i cant get more then 110 fps but its always around 80-90 i know 2k is demanding but in every other game i get constant 240 and can push to 400+ in most other games even in arc raiders i get 250-300 which i consider to look and feel more demanding then marathon by far there is no world where a game that looks like this runs this badly. I really hope it gets fixed on release because gamers are impatient and i really want this game to succeed
