For what is worth, I spent a few hours playing around with settings and I found out that If I keep everything at ultra or high settings but put CAR REFLECTIONS to Ultra Low, Mirrors to the lowest quality (also Ultra Low I think) and CROWDS to Low or lower, framerate and GPU utilization go way higher and I gain a TON on smoothness (I play at 144hz).
My setup is very similar to lots of people here (as I stated on a previous post), 5800x3D + 7900xtx.
I think some settings might be "broken" as I don't see a single core on my CPU getting to 100% (which might normally be the case for cpu-bound scenarios, which this looks like is not)
It work!, but now crash, i have a R7 5800x (oc to 4.95Ghz), rx6700xt (oc too), i will try whitout the oc, this game never crash to me, but i aways have the issue with low fps.
