Tuning QLC SSD Read Latency
During real-time ray tracing, the screen would suddenly freeze for 0.4 seconds, which is a disaster for a technical demo. I tried increasing virtual memory to 32GB in Windows, but this only made the system response sluggish—a wrong-direction optimization that made me furious. I used the GamePP NVMe Queue Depth Configuration to fine-tune the read queue depth to 1024. AIDA64 latency tests showed random read latency converged to 85-92ns, down from 110-130ns, while temperatures remained stable at 40-46℃ per HWInfo64.
