Is a firmware update needed for WD SN850X 1TB lag in Unknown 9?
While jumping between different dimensions, the screen would just freeze for about 0.5 seconds, which totally ruins the rhythm of a stealth game. The WD SN850X 1TB driver was struggling with non-contiguous small file reads, with response times fluctuating between 1.2-3.5ms, causing the game engine to hang briefly. I tried disabling all background disk scanning software in Windows, but the frame time spikes didn't budge—it was barely noticeable, which proved the issue was deeper in the firmware. I used the official tool to flash the latest firmware and used a partition manager to re-verify the 4K alignment. CrystalDiskMark showed random 4K read latency dropped from 0.8ms to 0.4-0.6ms, and scene transitions became way smoother. I actually had a scare where the disk wasn't recognized immediately after the update, but a full power cycle fixed it. Temps are sitting at 42-52℃. I/O stress tests now confirm the response times are well within the target range.
