Solving memory issues for Manli RTX 5080
In this massive open world, the frame rate was bouncing unpredictably between 80-110 FPS, which made me really worried about my VRAM overhead. The Manli Snow Fox GeForce RTX 5080 OC's 16GB GDDR7 was hitting 15.2-15.8GB when running 4K ultra textures, forcing the system to swap to slow virtual memory. I first tried increasing the page file to 64GB, which stopped the crashes but actually lowered my 1% lows by 5 FPS. It was a frustrating trade-off. I eventually dropped the texture filtering quality from 'Ultra' to 'High' and set the Power Management Mode to 'Prefer Maximum Performance' in the NVIDIA panel. GPU-Z showed VRAM usage drop to 12.4-13.1GB, and the stuttering vanished. I tried using DLSS Frame Gen at first, but it caused some weird ghosting until I dialed the sharpening back to 50%. Core temps are now between 64-71°C. After several stress tests, the VRAM scheduling is finally optimized. Hardware parameters verified, and frame times are stable at 5.1-6.4ms.
