Does Lost Ark cause too much memory fragmentation on Corsair Vengeance LPX DDR4 3200MHz during raids?

Every time I entered an 8-man raid and the screen filled with effects, the game would just hang for 2 seconds. In a competitive setting, that's basically a death sentence. With 16GB of Corsair Vengeance LPX DDR4 3200MHz, my memory usage was hitting 92-96%, forcing the system into constant page swapping. I tried using those 'RAM cleaner' apps, but they just made the stuttering worse by forcing cache flushes at the wrong time. I ended up manually setting the virtual memory to 32GB and forced it onto a dedicated partition on my NVMe SSD, while killing three useless telemetry services. Resource Monitor showed the commit charge expanding from 18GB to 26-30GB, and the hard freezes stopped. I tried letting Windows manage the size at first, but the page file kept jumping between the C and D drives, causing massive I/O lag. Now RAM temps are 40-45℃ and CPU usage is a stable 65-72%. The input lag is gone, and it finally feels responsive.
