F1 25 freezes at 99% during track loads with my Zhitai TiPro9000 4TB; is this an SLC cache overflow issue?

During the track prep phase, the loading bar would just hang at 99% for several seconds, which is incredibly annoying in a game about extreme speed. HWInfo revealed that once the Zhitai TiPro9000 4TB SLC cache filled up, write speeds plummeted from 7000MB/s to 1200MB/s, causing a massive resource bottleneck. I tried disabling disk indexing, but that just lowered CPU usage without affecting load times—software tweaks are useless against physical cache limits. I installed the latest NVMe drivers and changed the write cache policy to 'Force Flush' in Device Manager, while also tweaking the defrag schedule. Real-time monitoring showed random reads jumping from 60-75MB/s to 85-98MB/s, and the loading hangs vanished. I did hit some brief response delays during huge file writes after the change, but switching to 'High Performance' power mode fixed it. SSD temps stayed at 45℃ - 55℃ with fans at 1200 - 1400 RPM. Frame times are now steady at 5.1ms - 6.4ms.
