Fixing cache overflow on Zhitai TiPro9000 in Deathloop
It's honestly ridiculous—this limited edition drive's SLC cache fills up during Deathloop's fragmented loading, and the write speed just craters to below 1GB/s, causing huge hitches. I tried disabling every single background update in Windows, but the loading speed didn't budge and the stutters actually got worse. Total waste of time. I realized the driver was mishandling 4K random reads, so I updated to the latest vendor driver and forced the write cache to 'Enabled'. Using a monitor, I saw random read latency drop from 1.5-3.2ms to a tight 0.8-1.2ms, and frame times went from 22.1-31.4ms down to 16.2-19.8ms. I originally thought it was overheating and slapped a massive heatsink on it, only to find it was idling at 42℃. The cache still fluctuates under extreme writes, but the general loading speed is way better now. Logged everything in the performance analyzer, and the fan is humming along at 1400-1600RPM.
