PotionLevelFix officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.20.1, 1.20. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with PotionLevelFix – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if PotionLevelFix consumes the most tick time.
