FarPlaneTwo Is a mod that allows for LOD rendering, 

Q: what is LOD.

A: It's so something far away renders with lower quality than it would close up.

WARNING, I DID NOT MAKE FARPLANETWO, This is just a way to play FarPlaneTwo again Since it hasn't been updated.

Known Bugs:

1. Breaking blocks may cause the game to crash. This happens consistently, so avoid breaking blocks unless you know a workaround.

2. Throwing items using the usual drop key (Q) can also cause a crash. You can avoid this by manually dragging and dropping items out of your inventory.

3. The only KNOWN way to fix this is removing the mod "malisiscore" but this mod is needed for custom world gen, so i just recommend being more careful around hitting mobs and other stuff,

There are two render modes, 

[1] Voxel, This render mode for LOD is more high quality in generating chunks, but takes longer to load

[2] Heightmap, This render mode is better, But it has lower quality render maps, takes less time to load
