Hello and thank you for the response.
I can't measure the exact amount of frame drops, but they do happen commonly when i am strafing/turning around, run fast etc.
I have recently started the game, they happen everywhere as i can understand, even in the houses, or the church in the Wellington Wells. Not at the same degree though, i notice them mostly when i exit the first hatch in the large garden area in Wellington Wells, in which i have to get the train moving. Now I have the mission to enter stealthly to the Headboy camp.
As a general fact, frames are better in closed areas, but not always 30 fps, while in large areas the game is nearly unplayable. Even if I move my character slowly i notice them.
In 1080p mode (set in Xbox one X) on a 4k tv with HDR, frames improve a bit, but not at the constant 30 fps level.
However, the full immersion is in 4k mode guys it's an AMAZING game and congrats for the reception and creation of this masterpiece. The technical issues take it down and it's a shame.
If it could reach, not a perfect frame, but a pretty constant one near 30 fps, this would be something else!!
