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.

Q: Is this mod playable with a Potato pc?

A: most likely not, but maybe with a lower render distance then yes, but then that means you are limited to a few thousands blocks rather than millions like advertised,

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. Unless you Delete the mod "Malisiscore" but if you do, you wont be able to Generate Custom worlds, and be stuck to the default, as it is a gui config for this mod

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. yet again, Unless you Delete the mod "Malisiscore" but if you do, you wont be able to Generate Custom worlds, and be stuck to the default, as it is a gui config for this mod

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
