How to stop combat stutter in WoH 2 with Gloway DDR5?

Summoning units caused instant stutters. Setting virtual memory to half disk space made it worse. I used GamePP NVMe Queue Depth Config to raise depth to 2048. HWiNFO showed temps at 42-55℃. CrystalDiskMark confirmed 4K random read improved from 45-52MB/s to 68-75MB/s. Combat is finally fluid and responsive.
