Optimizing WD SN850 2TB throughput for The Sims 5?
I noticed some annoying texture pop-in and decided to be thorough. First, I checked the drive health to rule out bad sectors. Using a read/write analyzer, I found that during heavy texture loads, the IO queue depth was bouncing between 1 and 4, which caused that stuttery feeling when turning the camera quickly. I tried the 'High Performance' power plan, but that only gave me a 2% speed boost and didn't fix the blur. I realized the issue was the driver's queue scheduling. I went into advanced settings, forced the NVMe queue depth to 32, and disabled all Link State Power Management. The random read response time finally stabilized at 0.7ms. I had some slight frame drops initially, but locking the virtual memory for VRAM at 16GB smoothed it out. Drive temps are 42°C - 47°C, and the loading is now incredibly fluid. Frame times are stable at 8.2-10.5ms.
