Speedy PC

This modpack is designed for maximum FPS.

In curseforge click the gear in the bottom left, click Minecraft, then copy and paste the following under Additional Arguments:

-Xms9G -Xmx9G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1

For general gameplay and not maximum FPS, go in video settings to set your max FPS to 60, cloud quality to fancy, particle quality to high, render distance to 21 (going above 21 can cause lag spikes).

In a world type /chunky radius 5000 and /chunky start. If you are on a server, chunky must be also installed server side for this to work.

If you still have lag issues, plug in your computer to make sure low power mode is disabled, and restart your computer. You may get more FPS when windowed.
