If your FPS drops in Minecraft due to the small amount of RAM, then try to download the FoamFix mod. It optimizes the allocation and release of RAM, which can significantly speed up the game. The authors of the mod also recommend the additional use of Better FPS, which further improves performance. In addition, FoamFix is available for both Fabric and Rift.
How to install FoamFix mod
- Make sure you have installed Minecraft Forge.
- Download the mod for your version of the game.
- Put it in the ‘mods’ folder, which is located in the game folder.
