Low FPS in raid on monster PC?

Hey, so i have a 4070ti, i9 13900k, 32gb DDR5 RAM. All my temps are great, PC is only a few months old, but whenever im raiding im always stuck at around 35 fps. I never go above 50. Is this normal? Ill be at 250fps before the fight starts, but once spells are being casted and swirls appear etc, my fps is at around 30-40. All low settings btw

UPDATE: Not sure if people still have this problem, but its becoming more of a known issue. Its an issue with 13th gen cpus. Seems like turbo mode and other overclocking things cause it. I put my p cores to a max of 53x or 54x and the issue completely stops. (yes underclocking it sucks).
