Is the WD SN850 1TB struggling with I/O requests in CP2077?
Driving through the neon streets of Night City, I kept getting these 0.2-second freezes that completely ruined the immersion. Even though the SN850 is fast, the I/O request queue was hitting 20-35ms of abnormal latency under the heavy load of Overdrive mode. I tried the generic 'Game Mode' in the drivers, but it was just a surface-level fix that didn't touch the I/O blocks. I installed the latest official WD NVMe driver, switched the Windows disk policy to High Performance, and killed the Indexing service. RivaTuner's frame time graph went from a jagged 15-45ms mess to a smooth 8-12ms line. I did notice my file search became slower after disabling indexing, so I had to add the game folder to the exclusion list. Temps are stable at 42-52℃. The I/O blocking is finally dead, though the drive runs a bit warmer under load.
