Better FPS Render Distance is a mod which adds a few performance improvements to increase fps.
This is the forge version of Better Render distances, for the Fabric version click here: Fabric

Render distance:

By default minecraft renders everything in a square radius(cylinder in 1.18), this is changed to a 3d circular radius which can be stretched horizontally and vertically via config or video option(video options button is not available with optifine). The higher the stretch the less caves below you will be rendered, esp distant ones. Provides about 10-35% less chunk sections to be rendered and thus gives a neat fps boost.

Requires Cupboard dependency to be installed in newer versions

Set horizontal render distance scaling
Set vertical render distance scaling
Choose if the adjust distance should also affect the range at which entities render
Debug mode to display effects

If you want to use this with Distant Horizons, set the vertical stretch to 100% and horizontal to 0%
Only required on clientside. Can be put on serverside but does nothing there.
