How to fix frame drops during combat in SCARLET NEXUS with Fanxiang S790E?

During superpower battles, triggering massive particle effects caused write response times to soar to 12-28ms per AIDA64, creating a jarring stutter. I first tried clearing system temporary files to free up space, but it provided zero performance gain. I used GamePP NVMe Queue Depth Configuration to increase write depth from 32 to 64 and disabled background indexing. CrystalDiskMark showed an 11% increase in random writes and GamePP benchmark confirmed response at 2.1-4.5ms. HWMonitor showed 48-62℃.
