“Switching from OpenGL to Vulkan will have an impact on the mods that currently use OpenGL for rendering, and we anticipate that updating from OpenGL to Vulkan will take modders more effort than the updates you undertake for each of our releases,” explains Mojang. “To start with, we recommend our modding community look at moving away from OpenGL usage.”
Question: how much does your typical content mod decide what’s going to be rendered? Is this something typically handled by Fabric/Quilt/[Neo]Forge?
Because I can quite guess OptiFine and the likes will need a lot of elbow grease, but I’m not sure about the rest.




AFAIK all modpacks are made for specific versions of Minecraft, so the current modpacks are completely unaffected. And even for future modpacks, the modpack creator doesn’t need to care too much about this, since it’ll affect the mods directly. (A modpack is, like the name says, just a pack of mods stitched together and glued with some configs.)
Plus popular modpacks are often for extremely old MC versions; for example a lot of people still run modpacks made for 1.16.5 (4yo), 1.12.2 (8yo), or even 1.7.10 (12yo).
