You may experience low FPS (frames per second) in your lovely game Minecraft. It is because the game is not fully optimized as it is written in Java. Minecraft also have some stuttering issues in big cities on high-end computers with plenty of cores and RAM. What we can do? The only solution is tweaking. If you are experienced user, then you will have no problems, but many users will. So we developed automatic installer named Minecraft Tweaker, which will allow you to install modifications, optimize your configs and more. For older computers we recommend lowering render distance and Fast option in Quality settings.
