I'm not sure if this an issue on my end, but I'm experiencing frame issues only in the entertainment district.
It does chug a little there, though it shouldn't be horrendous most of the time. Minimum requirements are a Ryzen 3 or equivalent. May optimize further eventually (both map and upgrading the frameworks used), but that's a ways in the future.
I'm not experiencing it anymore. So most likely just an issue on my end!
