30fps limit issue on fh5 with 2060 rtx super / 1920x1080p

Hi, I have a problem from day one, I use a 2060 super and a 1080p monitor. the game suits me perfectly with high graphics 60 fps and 50% gpu usage. Every now and then the game suddenly hits me and limits me to 30 fps … To fix it I just have to go to video options and change the resolution. Then I discard the changes and it works again at 60fps without restarting the game. How can I solve this problem?

after several days and trying hundreds of things I still can’t find a solution
