How do I fix SLC cache overflow and write speed fluctuations in Ratchet & Clank?

Loading new areas in Ratchet & Clank was chaotic. My YMTC Zhitai Ti600 500GB SLC cache kept overflowing, causing write speed to fluctuate wildly. I tried clearing background apps, but system services interfered. It was a waste of time. I used the GamePP Resource Scheduler to elevate the game process to real-time priority and enable forced write cache refresh. Benchmark tests showed write speed stabilized at 3500MB/s. Drive temperature held at 48-52°C. This verified the fix.
