Fixing WD SN850 2TB read/write drops in TLOU 2 PC?
The texture pop-in while sprinting through urban ruins was absolutely jarring and ruined the immersion. Checking my logs, the drive's read speed plummeted from 6000MB/s to 1200MB/s when streaming 4K textures, which triggered the FPS dips. I tried toggling 'High Performance' mode in the drivers, but that actually made the stuttering 10% worse—a total facepalm moment. I realized it was an SLC cache management issue. I manually locked my virtual memory to 16GB on a separate non-OS partition and ran a full TRIM optimization. After the reboot, read speeds stabilized between 5200-5800MB/s, and the drops vanished. I did notice the system boot took 2 seconds longer after the TRIM, but a quick tweak to the fast boot settings fixed that. Drive temps are chilling at 45-52℃. Ran 10 consecutive AIDA64 read loops with zero errors, and memory temps stayed within 45-52℃.
