How do I reduce key response latency in Metaphor: ReFantazio gunfights?

I was losing 1v1 gunfights in Metaphor: ReFantazio because my inputs felt mushy. NVMe queue depth was over 95% per GamePP, causing high latency. I tried increasing virtual memory, but it was a waste of time. I used GamePP NVMe Queue Depth Configuration to increase my Western Digital WD Black SN770 2TB queue depth from 1024 to 2048. Now, input latency is under 8ms per GamePP Stress Test, and drive temp is stable at 42-45℃ via GamePP Sensors. This setup is crucial for winning close matches.
