way better result i'm used to.
make me wonder if a driver update is the reason because my finding back in 2016 early 2017 where confirmed by other user and yours are not even close to it.
i wonder why noone else is noticing such a giant permanence increase and reportet it.
that's only about 1.5-2x.
BTW. i was using SM back in the days.
i saw stuff like 150 ms with my 480 back in the days (ngu was used on chroma doubling too).
