Is Manli RTX 5080 16GB stuttering in MGS Delta at 4K?

How is 16GB of VRAM already full? This Manli RTX 5080 OC turned into a slideshow in the jungle scenes, which is just ridiculous. First, the map loading bar would just hang at 99% while the PC thought about life; then, one turn and the FPS tanked to 15. I tried dropping settings to Medium, but the game looked like a blurry mess from 20 years ago. I finally fired up the GamePP Memory Controller Load Monitor and triggered a forced VRAM address remap, while cranking the virtual memory from 16GB to 64GB. Surprisingly, the 1% lows jumped from 22 FPS to 58 FPS at 4K. The GPU fans sounded like a jet engine taking off, but at least the stuttering stopped.
