I don't know my version or loader
This modpack focuses on improving performance to the maximum, using only the best optimization mods and no unnecessary mods that affect performance, to give you the best FPS in the new versions. It's also perfect for playing on servers. (Performance may vary depending on your PC. In my case the FPS is tripled compared to vanilla.)
If you want to have the best performance, i recommend you to pre-generate the world with Chunky. For example, if you want to generate the chunks with a radius of 1000 blocks from the spawn, you should set the following commands: chunky world <world> to set the current world. chunky spawn to set the center in the spawn. chunky radius 1000 to define the total radius to 1000 chunky start to start the task.
Main optimization mods
➤ Sodium: This is the most important mod that is responsible for greatly optimizing the game.
