I'm seeing massive FPS swings in combat in The First Descendant because my ADATA ValueRAM 4GB DDR4 2666 is maxed out. Should I use memory compression?

The fact that this game even boots on 4GB of RAM is a miracle; I actually got a rush of excitement seeing a steady 40 FPS. With a 12GB minimum requirement, the ADATA ValueRAM 4GB DDR4 2666 is forced into a constant cycle of page swapping every 20-40ms. I first tried dropping every single texture setting to the absolute minimum, but the game looked like a pixelated mess from the 90s—it was stable, but I couldn't stand looking at it. I then went into the registry to force-enable Windows memory compression and killed every unnecessary system service to squeeze out an extra 300MB of physical RAM. Using a frame time analyzer, the generation intervals stopped jumping between 15-60ms and settled into a relative 22-35ms range. Enabling compression did bump my CPU usage by 5%, pushing core temps from 68℃ to 74℃, but that's a fair trade to avoid crashing. RAM temps were 40-46℃ and VRMs were 55-61℃. Confirmed the resource scheduling shift via the in-game performance panel.
