Distant Horizons Vulkan and Raw OpenGL Errors
Distant Horizons depends on the Minecraft rendering environment. Vulkan wrappers, shader loaders, GPU drivers, and loader versions can all change the failure mode, so identify the renderer before tuning LOD distance.
Common symptoms
- Minecraft reports a raw OpenGL error
- the game crashes when entering a world
- Vulkan Mod is installed
- the issue only appears with shaders or a specific GPU
Step-by-step fix
Remove Vulkan Mod for the test
The official compatibility list identifies Vulkan Mod as a known incompatibility direction. Test with the standard Minecraft OpenGL path first.
Update the GPU driver
Install a stable driver for your GPU and restart the computer before comparing results. Avoid changing the driver and every mod at the same time.
Test without shaders
Disable shader packs and test DH alone. If the crash disappears, add a documented DH-aware shader one at a time.
Check the first renderer error
Open the latest log or crash report and record the first OpenGL, Iris, Sodium, DH, or loader error rather than only the final exit code.
Keep one rendering stack
Do not combine OptiFine, Iris, duplicate Sodium ports, Vulkan wrappers, and other render replacements while diagnosing a crash.
Still stuck?
Record your Minecraft version, DH version, loader, shader pack, GPU, and crash log before asking the community. That information makes compatibility problems much easier to diagnose.
