Cull Clouds
This Fabric mod introduces a small optimization to the cloud rendering process by excluding from rendering those parts that are not visible to the player, which allows for a slight performance improvement.
It's important to note that the mod only works with the "Fancy" cloud setting.
Development Status
Mod development has been suspended since Cull Clouds functionality has been integrated into newer versions of Sodium. The author considers further updates unnecessary.
Additionally, the performance improvement from this mod is quite modest - in normal gaming situations, it usually provides only +1-2 frames per second.
Compatibility
The mod has limited compatibility with other cloud modifications:
Extended Clouds - completely incompatible with Cull Clouds
SuperFancyClouds - runs together, but Cull Clouds has no effect
Other conflicts are possible since to optimize vanilla clouds, Cull Clouds essentially rewrites their rendering system.
Performance
FPS comparison between standard version and version with Cull Clouds:
On regular worlds, the performance improvement is minimal - usually just 1-2 additional frames per second
