How do I stop Kioxia EXCERIA PLUS G3 2TB frame drops in Once Human melee?

I dropped from 240 to 120 FPS in a Once Human melee, losing my aim. I lowered textures to High, but the visual loss was painful. I used GamePP Power Plan Switcher to move from Balanced to High Performance. RTSS showed frame time stabilized from 4-15ms to 3-4ms. Read bandwidth hit 85-92%. This power setting is the best way to set your frame stability.
