They should either keep an OpenGL version, or force GPU companies (mainly Intel, with their iGPUs) to add full Vulkan support.

I might actually do that, especially since I have dealt with configuring some knockback settings!

Edit: I currently have a development branch (for WIP guides). But, after it is done, you can contribute to the project — it would help a lot, especially considering that this is currently a one-man project!

I know how late I am to the party, but here are some ways that Minecraft should be revolutionized:

• Officialize mods, and make versions into mods (certain bug fixes should exist, but for “useful” bugs, make a toggle). Beta 1.7.3 could be the base/core.
• Overhaul the rendering engine. An unofficial Discord server owned by Minecraft developers called “Vibrant Vanguard” says that they’re already doing this, and they’re also actively talking to optimization mod developers.
• Recode in Kotlin. Kotlin is a JVM bytecode language, so it’s still compatible with Java, and has multiple benefits. This would also make the developers clean up code, making Minecraft more performant.
