How do I fix the storage scheduling on a Samsung 9100 PRO?

Whenever I hit those massive open-world maps, the loading bar just hangs at 75% for a few seconds, which totally kills the immersion. I realized the Samsung 9100 PRO's dynamic SLC cache fills up way too fast, causing write speeds to tank from 12,000MB/s to under 1,500MB/s, which spikes the I/O wait times. I tried bumping up the virtual memory in Windows, but on a PCIe 5.0 drive, that did absolutely nothing—it actually made the system feel sluggish, which was honestly baffling. I eventually dove into Device Manager and pushed the NVMe controller queue depth from 1024 up to 2048 and forced the write cache buffer flushing policy. Running CrystalDiskMark, my random 4K reads jumped from 45-58MB/s to 68-82MB/s, and the stutters completely vanished. Interestingly, right after the queue depth tweak, I noticed a weird recognition lag during idle, but switching the power plan to High Performance sorted it out. The drive stays around 48-55℃ now, and the heatsink feels warm to the touch. Confirmed everything is locked in via the motherboard utility; the performance parameters are finally saved.
