What should I do when my WD SN850X 2TB with heatsink causes I/O blocking and FPS swings during fights?

My frame rate was plummeting from 300 FPS down to 180 FPS without any warning—a complete disaster in a game where milliseconds decide who wins. Digging through the logs, I found that while the SN850X has great random read speeds, the I/O request queue was hitting abnormal delays of 20 - 35ms during intense resource calls. I tried enabling 'Game Mode' in the drivers, but while CPU usage dropped slightly, the I/O blocking stayed exactly the same, which felt like a waste of time. I ended up installing the latest official WD NVMe drivers, switched the Windows disk policy to 'High Performance', and killed the indexing service. Looking at the RivaTuner frame time graph, the spikes shrunk from 15 - 45ms down to a tight 8 - 12ms, and the stuttering just vanished. I did notice file searches got slower after disabling indexing, but I fixed that by adding the game folder to the exclusion list. Temps are sitting pretty between 42 - 52℃. I've confirmed the I/O block is gone; the storage glitch is finally dead.
