-
FPS Stabilization:
- Ubinilium actively stabilizes your frames per second (FPS), ensuring smoother gameplay even in demanding situations.
- By optimizing rendering and chunk loading, it minimizes FPS fluctuations.
-
Distance-Based Rendering:
- Blocks beyond a certain distance (4 chunks) are intentionally rendered with lower detail.
- This approach balances visual quality with performance, as players are unlikely to notice distant blocks’ reduced fidelity.
-
Memory Caching:
- Ubinilium intelligently caches data in memory, reducing the strain on your system’s RAM.
- This optimization helps prevent memory-related performance bottlenecks.
-
Asynchronous Chunk Processing:
- The mod asynchronously processes chunks, allowing smoother world loading and unloading.
- This results in a more responsive experience, especially when exploring large areas.
-
Progressive Optimization:
- Ubinilium scales its optimizations based on the number of loaded chunks.
- The more chunks you have active, the greater the performance boost it provides.
