This is the first release of tic-tacs for 1.16.2! Although it should be relatively stable, this is absolutely not production ready: please make a backup of any world you plan to use with this mod!
Essentially, this mod replaces Minecraft's chunk generation logic, both making it faster, as well as allowing for the generation of chunks in parallel over multiple threads. In addition, the mod does a lot of work to minimize the impact that chunk generation has on the main server thread (and consequently tickspeed). This is done by optimizing the logic that the game uses for chunk and entity tracking, as well as making sure various vanilla logic avoids blocking the main thread to wait for a chunk to be loaded.
If you are experiencing chunk corruption relating to other mods' generation, you can set the thread count to 1 in config/tic-tacs.json. You should still experience performance improvements over vanilla with just 1 thread.
This release should be compatible with both Lithium and Phosphor.
