How to fix loading freezes in Mageseeker with Samsung 9100 PRO?

I expected instant loading with PCIe 5.0, but the loading bar would frequently freeze at 90% when entering Summoner's Rift, which was a total pain. I tried updating the motherboard chipset drivers, but the loading time actually increased by 2s per CrystalDiskMark, which was incredibly frustrating. I used GamePP NVMe Queue Depth Configuration to increase the depth from 32 to 128 and enabled forced write cache flush. Loading time dropped from 12s to 4s per CrystalDiskMark, and temps stayed 48-52℃ per HWiNFO64.
