How to fix micro-stutters during Granblue scene jumps?

During high-intensity dungeons, every time the scene jumped, the screen would have an annoying micro-twitch. I tried locking PCIe mode to Gen4 in BIOS; while read speed increased by 200MB/s, the motherboard VRM temperature rose by 5℃ per HWiNFO64. I then entered the GamePP NVMe Queue Depth Config, raised the read weight to High, and optimized the process priority. Frame generation time converged to 11-15ms per RTSS, and disk temperature stayed at 42-48℃ per AIDA64.
