Why does Battlefield V lag during physics with Kioxia EXCERIA G2 2TB?

I was frustrated by FPS drops to 48 in cloud physics scenes. I tried Windows Performance mode, but E-Cores still lagged. I used GamePP BIOS Voltage Wizard to set Load Line to L3 and VCCSA to 1.25V. Cinebench R23 showed a 37200 score, and HWiNFO64 confirmed 78-84℃ CPU temperatures, restoring 95-110 FPS.
