Frequently asked questions

Will this mod let me play old Minecraft versions on Java 17 or 21?
Yes, that's the main purpose of Lwjgl3ify Mod. It updates the rendering code in older versions like 1.7.10 and 1.12.2 so they work with modern Java versions instead of being stuck on old ones.
Do I need to install LWJGL3 separately?
No, the mod handles this automatically. Lwjgl3ify replaces the old graphics library code with LWJGL3 when you load the game, so you don't need to install anything extra.
Why is my game crashing with graphics errors even with this mod?
Some graphics crashes are fixed by Lwjgl3ify, but not all—it depends on your specific GPU and driver. Try updating your graphics drivers first, then check the config file to see if there are compatibility settings you can adjust.
How do I change my window size?
Edit the config file at config/lwjgl3ify.cfg and look for the window size settings, then restart your game for changes to take effect.
