The game runs fine at first, then after 1-2 hours FPS drops and stutter appear. RAM usage grows to 6-10 GB even in quiet zones.
The client does not release memory used by loading screens, UI elements and addon data. Over time this reduces available memory and forces disk swapping.
Restarting the game is a temporary fix. The permanent solution is automatic memory cleanup — the fix tool does exactly this in the background.
