Fixing Zhitai TiPro9000 read speed drops in Forza Horizon 5?
It was honestly ridiculous—this limited edition drive was giving me HDD-level load times while speeding through the map. I found that once the SLC cache on the Zhitai TiPro9000 filled up, the 4K random read speeds crashed from 7000MB/s to around 1200MB/s, causing texture pop-in delays of over 100ms. I wasted a few hours trying to increase the virtual memory page file, but that just pegged my disk I/O at 95% and made everything worse. I finally installed the latest NVMe drivers and disabled the 'Write Cache Buffer Flushing' policy in Device Manager. CrystalDiskMark showed 4K random reads jumping from 48-55MB/s to 65-72MB/s, and the map hitching completely vanished. I did notice a slight delay during cold boots after disabling the cache, but switching the power plan to 'High Performance' killed that issue. Drive temps stayed around 45-55℃. I exported the I/O error logs via Event Viewer to confirm the fix, and my fans stayed steady at 1400-1600RPM.
