Why is loading saves so slow in Nioh 2 with the FireCuda 510?

Every time I died and reloaded, the wait felt like an eternity, which is brutal in a fast-paced game. I initially tried moving the game to a different partition, but the read speed barely budged. I finally accessed GamePP NVMe Queue Depth Configuration, increased the depth from 32 to 64, and optimized the write cache flush policy. CrystalDiskMark showed 4K random reads rose to 42-47 MB/s, and AIDA64 confirmed stable temps at 38-45℃. Now I'm back in the fight almost instantly.
