About this Mod

Prefer OpenGL

This project includes loader-specific entrypoints for:

Fabric
Quilt (in development)
Forge
NeoForge (in development)

All variants call the same shared logic to force an OpenGL renderer preference by editing options.txt.

Shared behavior

On client startup, each loader entrypoint ensures one of these keys is set to OpenGL:

graphicsApiPreference:prefer_opengl
graphicsApi:prefer_opengl (legacy fallback)

If neither exists, it appends graphicsApiPreference:prefer_opengl.

Important note!

This mod fixes crash on Amethyst Launcher (and other mobile java launchers) which does have vulkan but doesn't have some librarys. So, Minecraft switchs to Vulkan API and crashes. More ever what this mod does is it forces OpenGL as the renderer API. And if you're device supports Vulkan API please don't use this mod first try if Vulkan works or not.

Frequently Asked Questions

Prefer OpenGL server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.2-pre-1). You can switch loaders with one click in the panel.

Is Prefer OpenGL compatible with fabric and forge?

Prefer OpenGL officially supports fabric, forge for Minecraft 26.2-pre-1, 26.2-snapshot-8, 26.2-snapshot-7. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Prefer OpenGL – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Prefer OpenGL consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
