Hellblade II is stuttering during heavy physics scenes on my Kioxia Exceria Plus G4 1TB. Should I be messing with Load-Line Calibration?

Every time there's a massive particle effect or something breaks in the environment, the game just hitches. It's a basic scheduling issue that's honestly pathetic for a modern title. The G4's PCIe 5.0 bursts were causing the motherboard's VRM to dip by 0.07V, which made my CPU clock dance erratically between 3.5GHz and 4.2GHz. I tried enabling the 'Ultimate Performance' mode in Windows, but my CPU hit 94℃ and started thermal throttling—totally the wrong move. I went into the BIOS, set Load-Line Calibration to Mode 3, and manually set Vcore to 1.26V. In Cinebench R23, my multi-core score jumped by 500 points and the frequency line became a flat plane. Mode 3 actually caused a boot failure on the first try, so I had to offset the voltage by 0.01V to get it stable. CPU is now 76-82℃, SSD is 55-62℃. I backed up the profile in BIOS, and it's been perfect since.
