Strange problem in 007 first light

[cym104]

radon 9070 xt, rtx 3080 laptop, i9-11980hk, adrenaline 26.7.1, gefoce game ready 610.88, windows 11 25h2 26220.9022, 2k 144hz monitor with adaptive-sync.

if i run the game clean with nothing in the background, i get severe micro stutters, and the 1% low fps is in single digit. average fps at ~75, spike fps at ~270.

but as soon as i start to monitor the game using presentmon GUI, the game goes to a very smooth state: the 1% low fps increase to ~125, and the average fps goes to a rock solid 144.
and as soon as i stop monitoring the game in presentmon GUI, the problem comes back.

i tried other monitoring tools like RTSS/afterburner and presentmon CLI, none have the same effect.
this problem only happens on the 9070xt, not on the 3080 laptop. no problem with any other games.

from presentmon CLI, i can see that:
