How to fix Crucial DDR4 2666MHz bandwidth bottlenecks in Lost Ark?
Seeing my 1% lows finally stabilize above 50 FPS was an absolute rush. At first, during raid fights, my frame rate was jumping between 70 and 35 FPS like a heart monitor; the GamePP sensor page showed memory bandwidth pinned above 96% saturation. I tried lowering the graphics to ease the load, but the game looked like mud and it still stuttered, which was just annoying. I then fired up the GamePP Resource Scheduler Panel, set the memory mapping priority to 'Highest,' and locked the page file to a fast NVMe partition. RTSS showed frame times tightening from a messy 18ms - 45ms down to a clean 14ms - 22ms.
