**Title:** The Performance Issues of Minecraft Java Edition: A Historical Explanation
**Summary:**
* Minecraft Java Edition, despite being a top game, is notorious for its lag and performance issues.
* The problem escalated with the "Aquatic Update" (v1.13), which introduced more realistic physics but required significant code changes, known as "Flattening".
* "Flattening" made blocks independent, increasing the game's data size and leading to substantial lag due to the game code struggling to manage the expanded data.
* Subsequent updates (v1.14 and v1.15) attempted to mitigate the issues with partial success.
* However, more recent updates (e.g., "Caves Update") have reintroduced performance problems, especially on older computers.
* The author predicts that future updates, with new blocks and mods, will necessitate another massive code change, potentially leading to similar complications, but ultimately to be resolved by the developers.
Here are the key facts extracted from the text, without opinions, numbered and in short sentences:
**Minecraft General Facts**
1. Minecraft is the number one game with one of the most significant performance issues.
2. Minecraft Java Edition had better performance in older versions (e.g., version 1.12).
**Version 1.12 Facts**
3. Version 1.12 was known as the "Color Update".
4. This update added new blocks (e.g., concrete, tile blocks) and features (e.g., parrots).
5. Version 1.12 was the last update with good performance and high FPS.
**Version 1.13 (Aquatic Update) Facts**
6. The Aquatic Update (version 1.13) introduced significant performance problems.
7. This update allowed players to place blocks underwater with realistic physics.
8. Previously, blocks underwater had a visible air gap around them.
9. The update required adding light data for each block, exceeding the game's initial limit (4,096).
**"Flatter" (Block Storage System) Facts**
10. "Flatter" is a block storage system change introduced in version 1.13.
11. Flatter made each block independent, eliminating the need for "ID" and "data" combinations.
12. This change increased the game's storage requirements, leading to performance issues.
**Performance Issues and Solutions**
13. Version 1.13's changes caused lag, especially with block variations (e.g., stairs with >80 combinations).
14. Version 1.14 modified chunk loading to alleviate some performance issues.
15. Version 1.15 focused on stability, improving FPS and accommodating game code for better performance.
**Later Updates and Predictions**
16. The Caves Update increased Minecraft world sizes, making them twice as heavy.
17. This update forced Minecraft to update its graphics engine and Java (to Java 16).
18. Older computers may no longer support Minecraft due to these updates.
19. A future, significant code change ( potentially "Flying 2") is predicted, which may bring new complications.
