Why do I experience micro-stuttering during scene transitions in Tomb Raider (New) with ADATA XPG D300 RAM?

The screen experienced micro-stuttering while crossing ruins, and I felt uneasy about the lag. I tried using default timings, but the latency remained high, and the stuttering persisted. I adjusted the memory timings to 28-28-28-68 using the GamePP Memory Controller Load Monitor. Latency converged to 95-105ns per GamePP, and scene transitions became smooth, confirmed by MemTest86.
