So since 25.3.1 driver we can't disable SAM through driver, but that thing ruining performance in this ONE particular game (in my experience).
Happening on 2 different systems (7500f+6600xt and 5800x+6700xt), and have seen multiple reports from users.
So AMD, please, either return toggle in AMD software or fix that issue already.
To back up my words i provide these links with exact same reports from players, people suggest disabling SAM on driver for workaround.

From now on, i'll update this thread monthly (with new drivers update), to check if this issue fixed or atleast they added back toggle for SAM.
forgot to mention also high VRAM usage with SAM ON.
issue persist on 25.3.2 driver, toggle to turn off SAM in driver didn't returned.
plus example of some location in game with low gpu utilization
apparently, this problem is present only in 6000 series? can't find any evidence that 5000 or 7000 have these problems.
screenshot with example how game works in same location with REBAR (aka SAM) OFF.
25.4.1 update:
Toggle for SAM didn't returned
Performance in this game with SAM on not fixed.
