Troubleshoot Visual Artifacts or Flickering

Check Shadow Settings

Flickering or banding artifacts often stem from shadow calculations. Open Shader Options and try adjusting shadow distance or shadow quality. Sometimes lowering these values eliminates visual glitches caused by shadow map precision issues.

Verify Compatibility Settings

Ensure your OptiFine version is current and compatible with your Minecraft version. Mismatched versions can cause rendering errors. Reinstall OptiFine if problems persist.

Disable Conflicting Features

If you're using other visual mods or resource packs, they may conflict with the shader. Try disabling them temporarily to isolate whether SapphireShaders is the source of artifacts.

Reset to Defaults

If troubleshooting doesn't work, reset all shader settings to default in the Shader Options menu. Then gradually re-enable features one at a time to identify which setting causes the problem. This systematic approach helps pinpoint the exact cause of visual issues.
