My Zotac RTX 2060 Super hits a VRAM wall in the new map, dropping to 30 FPS. How do I fix this lag?

That suffocating feeling when your frames tank right in the middle of a boss fight is the worst, especially in the dense environments of the Shadow Realm. The 8GB on my Zotac RTX 2060 Super is just not enough for 4K sampling; GPU-Z showed VRAM usage pinned at 95-99%, forcing the system into a virtual memory swap that crashed my FPS from 60 down to a choppy 30. I tried bumping my system page file to 32GB, but that did absolutely nothing for the smoothness—it just made the stutters feel more random and frustrating. I finally dropped the texture quality from Ultra to High and used DDU to wipe about 4.2GB of bloated old shader cache. In GPU-Z, the VRAM usage dropped to a stable 7.2-7.8GB, and the frame rate stabilized between 52-58 FPS. I noticed some distant assets looked a bit muddy after the drop, so I kicked in NVIDIA Image Scaling (NIS) to bring back the sharpness. Core temps stayed at 72-78℃ with fans at 1800 RPM. VRAM temp held at 58-63℃, and the game is finally playable again.
