fps drops massivly

hello

after the dawn of the hunt i get massiv fps drops when using to much spells.. it drops from 140 fps to 60 fps and under when mapping. i normally play on 4k all settings standard.

i run a rtx 4070 , ryzen 7 5800x3d , 32gb ram ddr4 3200 mhz , 4k monitor and 2 1tb nvme ssd.

before update there was no fps problem at all maybe in the camps when all the players are there.

i tried several settings with and without upscaling nothing changed. even with 50% reduced resolution i get drops and i dont see anything its like playing with hiroglyphs.

i clean installed older windows 11 and gpu drivers.. cpu is under 79° C , gpu doesnt go higher as 72° C

dunno what else to do
