How to reduce memory latency in No Rest for the Wicked?

Exploring the depths of the dungeon, I noticed slight tearing when turning quickly; this latency is fatal for action. I tried increasing the page file size, but it actually dropped my FPS from 72 to 58, making me very hesitant. I used the GamePP Memory Controller Load Monitor to tighten timings to 32-34-34-72 and raise voltage to 1.35V. AIDA64 confirmed latency dropped to 68-72ns, and HWInfo showed memory temps at 45-51℃ with VRM at 60-65℃.
