BadOptimizations

What it is

BadOptimizations is a free Minecraft mod focused on client-side frame-rate performance. It uses a multi-loader approach and lists support for Minecraft versions 1.21.6, 1.21.7, and 26.2. The mod is intended for the game client, so it does not provide dedicated server support. Sodium is not required, allowing the mod to be considered without that dependency. Its client scope means the listed performance focus applies to the player-side installation rather than server operation. The project is available through its Modrinth website. Players should match the installation to one of the stated Minecraft releases and to their chosen supported loader. The free plan has no listed price. BadOptimizations is therefore aimed at players looking for a client-focused frame-rate mod that can work across supported loader environments, while server administrators should note that dedicated server support is not provided.
