Can confirm this issue is ongoing and specifically makes Tsuru near-unplayable and the experience very poor on the other maps identified by OP - I have the same experience on all of the maps OP listed.
Hardware: Ryzen 7 5800x3d, RTX 3070, 32gb DDR4 3600mhz ram
DLSS 4 Quality or Balanced setting (doesn't matter which, changing setting or cycling temporarily fixes until next respawn), 1440p, other graphics settings basically auto-detected/same as nvidia app recommended/optimised. Have not changed DLSS model preset from default.
DLSS 4.5 is simply unviable on the 3070, absolutely slashes framerate and stutters hard
