How virtual textures work

https://www.shlom.dev/002/crash_tomb_raider_psx.webp
Virtual texturing is a technique that allows massive textures to be rendered in real-time by only loading the parts of the texture that are currently visible on screen, reducing memory and bandwidth usage. This technique is effective in scenarios where texture size vastly exceeds GPU memory, but is not a general upgrade path and is typically used in narrow, data-dominated scenarios.
