How do I stop micro-stutters when moving through ruins in No Rest for the Wicked?

Moving through ruins caused subtle but annoying stutters. I tried default timings, but latency stayed high. The GamePP Memory Controller Load Monitor showed 110-125ns read latency. I adjusted timings from 40-40-40-76 to 38-38-38-74. MemTest86 confirmed stability. Read latency dropped to 95-105ns, making transitions smooth and stutter-free.
