I'm using NVIDIA GPU and vanilla resourcepack test shows reducing samples by fractional mip level obviously improves performance. With 16x16x16 trial spawner aligned to render chunk and player standing on...

This is mainly caused by when using anisotropic filtering, mipmap content will be undefined, like this nsight graphics capture:  However, undefined mipmap content also happens in OF 1.21.1, but...

I believe this is fixed in Optifine for 1.21.8. Mipmap contents are filled with correct result when builtin anisotropic filtering on, which means it may provide even better result than...
