Dealing with WD SN850 stutters in Code: Jie urban areas
When zooming out over the city, I'd get these slight hitches in the movement that became way more obvious as the map scaled up. The 4K random reads on the WD SN850 were fluctuating between 15-25ms when handling thousands of small model files, causing the CPU to stall for tiny fractions of a second. I tried lowering the shadow quality, which gave me a measly 4 FPS boost but didn't fix the stuttering—a cautious attempt that failed to hit the root cause. I eventually updated the storage controller drivers and enabled the write cache merging strategy in Windows. RTSS monitoring showed frame intervals tightening from a jumpy 18-45ms to a steady 13-19ms, making camera pans feel buttery smooth. I did notice the PC took longer to shut down after the change, but reconfiguring the Fast Startup options solved it. Drive temps stayed between 42-50℃ with a response time of 0.03ms. Performance Monitor confirms the R/W curve is finally flat, holding that 0.03ms response.
