I'm getting these annoying micro-stutters when switching regions in Horizon Online. Why is this?

While zooming across the massive online map, I hit these weird, stepped delays during scene loads. Even though the TiPro9000 1TB crushes sequential speeds, it struggled with 4K small files, with response times jumping wildly between 42ms - 68ms, causing the streaming assets to choke. I first tried slamming the Windows power plan to Ultimate Performance, but that was a bust—it didn't fix the lag and just bumped my idle SSD temps up by 4℃. I felt like I was chasing ghosts. Then, I used a partition tool to verify the 4K alignment and forced a TRIM command to clear out the junk. Checking with CrystalDiskMark, my random reads climbed from 38MB/s to 52-61MB/s, and the transitions finally smoothed out. I actually messed up the registry I/O priority on my first attempt, which slowed my boot time by 5 seconds until I rolled it back to default. Now, drive temps sit steady at 45-52℃ and the read/write curves are flat. After updating the firmware via the manufacturer's tool, my frame times finally locked in at 5.1-6.4ms.
