Why does Lost Ark crash on Manli Snow Fox RTX 5070 OC in cities?
Every time I entered a crowded main city, I was on edge because a crash was practically guaranteed. The VRAM usage on my Manli Snow Fox RTX 5070 OC 12GB would instantly spike to 11.5 - 12.1 GB, hitting the hardware ceiling. I tried cranking my system virtual memory up to 64 GB to act as a buffer, but while the crashes slowed down, my loading times increased by 30%, which just made me more anxious. I eventually dropped the texture quality from Ultra to High and enabled VRAM management optimization in the control panel, setting the cache priority to Performance. Monitoring via GPU-Z, the VRAM usage stayed locked between 9.2 - 10.5 GB, and my frame rate smoothed out to 110 - 125 FPS. I did notice some blurry textures after the first drop, but a fresh shader cache reinstall fixed that right up. The core temp stays between 65 - 71℃ with fans at 1500 RPM. After a 4-hour stress test, it's finally stable, though I still worry about future updates breaking this.
