Reduce Lag from Multiple Overlay Mods

Why Overlays Can Impact Performance

When multiple information mods use Overlay Lib to draw textures and colors onto blocks simultaneously, your game can slow down if rendering isn't optimized. Overlay Lib caches visual data in memory to prevent recalculating the same information every frame.

Optimization Steps

1. Limit active overlays: Only enable the overlay mods you actively need. Disable or uninstall overlays you don't use regularly

2. Check mod settings: Many overlay mods have options to reduce update frequency or render distance—lower these if you experience stuttering

3. Monitor memory usage: Overlay Lib stores cached data; if you're running many overlays, ensure your Java allocation is sufficient

4. Update mods: Newer versions often include performance improvements

Trust Overlay Lib's Caching

Overlay Lib automatically manages visual memory to keep your game responsive. You don't need to manually clear caches—the mod handles this efficiently. If lag persists after disabling overlays, the issue likely lies elsewhere in your modpack.
