Exact same issue.
In fact as soon as you have a monitor > 60 Hz you will have this issue...
I just changed from an old 1920 60 Hz to a QHD 165 Hz and the game is totally unplayable...
Real FPS are 60, rendered FPS are 12 (you can see that with nvidia if you have one when you activate performance overlay)...
I linked my new topic about that :

I have had this problem now for 2 months. I've tried to fix it through youtube videos however I thought my problem was different as my frames are not dropping it just is stuttering really bad to a point where it is unplayable. It happens when I start the game. I an run other games on high graphics. I have a ryzen 7 RTX 6700. 32 RAM I shouldnt be having this issue. I know someone with an i9 and 3070 and they have the same problem. It is frustrating
