Optimizing WD Black SN850 2TB for the new Tomb Raider
While sprinting through tombs, the ground textures would suddenly vanish and my character would just drop into the void. It's a total immersion killer, especially at 4K. The random reads on my WD Black SN850 2TB were fluctuating between 65-72MB/s, but some specific sectors had massive latency spikes, meaning model data wasn't hitting the VRAM in time. I tried lowering the texture quality, but the game looked cheap and I was still falling through the map—a frustrating realization that this was a low-level storage failure. I used the official utility to flash the latest firmware and switched my Windows power plan to High Performance to stop the drive from entering low-power states. CrystalDiskMark now shows a perfectly smooth read curve, and the world loads seamlessly. I did have a weird 3-second detection delay on the first boot after the update, but a quick reseat of the M.2 drive fixed it. Temps are stable at 42-48℃. Switched to performance mode and the clipping is gone.
