Fix Lag by Switching to the Performance Version

Deferred rendering is still being optimized, and the full Fantasy Vanilla pack is aimed at high-end devices. If your frame rate drops, your device heats up, or the game stutters, the pack's Performance version is designed for you.

What the Performance version changes

According to the pack's notes, it changes two things because they cost the most resources:

• Water: the water effects are changed to be lighter.
• Plant movement: the swaying of leaves and plants is changed.

The rest of the look, such as coloring, lighting, and skies, is intended to stay close to the full version.

How to swap versions

1. Go to Settings → Global Resources (or the world's Resource Packs screen).

2. Deactivate the full Fantasy Vanilla pack.

3. Activate the Performance version and put it at the top of the list.

4. Make sure only one version is active at a time. Stacking both wastes resources and can cause conflicts.

Extra tips for smoother play

• Lower your render distance in Video settings. Fewer chunks means fewer shadows and clouds to draw.
• Avoid huge oceans and dense jungles while testing. Water and foliage are the heaviest scenes.
• Close background apps before launching the game.

If the full version only lags in certain biomes, you can keep both installed and swap depending on where you're building.
