*Important – Chunk Generation : When creating a new world, it is strongly recommended to pre-generate chunks to ensure better in-game performance. To do this, use the following commands:
/chunky center to set the center of the generation (usually your current position).
/chunky radius to define the radius of chunks to be generated.
/chunky start to begin the chunk generation process.
Pre-generating chunks significantly reduces lag caused by real-time world generation while exploring.*
Additionally, for optimal performance, it is recommended to set the vanilla Minecraft render distance to below 10 chunks. Higher render distances with voxy can negatively impact performance, even with the optimizations included in OptiHammer
OptiHammer is a carefully designed vanilla-refreshed Minecraft modpack that enhances the core gameplay without losing the original identity of the game. The goal of OptiHammer is simple: keep Minecraft feeling like Minecraft, while polishing and expanding the experience with thoughtful, lightweight additions.
This modpack focuses on performance, visual clarity, and subtle quality-of-life improvements. World generation remains familiar, progression stays balanced, and survival mechanics follow the vanilla logic players already know and enjoy. Instead of overwhelming systems or complex tech trees, OptiHammer introduces small features that feel natural and intuitive, as if they could have been part of the base game from the start.
Exploration is smoother, building is more comfortable, and the overall game feels more responsive thanks to optimization-focused mods. Visual enhancements respect the original art style, avoiding drastic changes while making the world feel more alive and refined. Gameplay additions are carefully selected to avoid breaking balance or immersion.
