How do I fix NVMe queue depth backlog and input lag in Atomic Heart on YMTC Zhitai TiPlus7100 2TB?

I was stuck in the 1970s zone, watching my character lag while the TiPlus7100's write queue backed up. Task Manager showed 14.2-16.8GB memory usage, killing my flow. I tried clearing temp files, but it did nothing. I used GamePP Resource Scheduler to set the game process to Real-time priority and switched the power plan to High Performance. AIDA64 confirmed the memory controller stabilized, and GamePP Monitor showed frame generation intervals dropping from 8.3-12.1ms to 5.1-6.4ms. Disk temperature held at 58-63℃ per AIDA64, letting me save my progress without a hitch.
