Description
COBALT

Cobalt is an experimental Minecraft mod designed to significantly enhance game performance through intelligent chunk rendering. By dynamically loading only the chunks in the player's direct line of sight and immediate surroundings, Cobalt aims to boost frame rates and reduce GPU load, particularly in complex worlds or when using high render distances.
Key Features:
- Selective chunk rendering based on player view
- Maintains a small buffer of always-rendered chunks around the player
- Temporarily retains recently viewed chunks for smooth transitions
- Invisible implementation for seamless gameplay experience
Performance Impact:
- Potential for substantial FPS increases, especially in demanding scenarios
- Reduced GPU workload and memory usage
- Possible slight increase in CPU utilization
Without mod:

250 FPS on average
With mod:

350 FPS on average
Client-Side Only:
Cobalt is exclusively a client-side mod. It is not required or used on the server at all. This means you can use Cobalt on any multiplayer server, whether it's a vanilla server or one running other mods, without needing to install anything server-side.
WARNING: Early Development Stage
Cobalt is currently in its early stages of development. Users may encounter bugs, unexpected behavior, or compatibility issues with other mods. Performance gains may vary significantly depending on system specifications and world complexity. Use at your own risk. If you're experiencing any issues with the mod please report them here.
Ideal for players looking to push their render distances further or those struggling with performance in complex builds. Cobalt offers a unique approach to Minecraft optimization, promising a smoother experience without compromising on view distance.
