This feature adds the /surge animation command. If this command is executed, texture animation will be disabled. This will prevent things like water or lava from having animated textures, but it will also increase performance. Running the command again will disable the feature, allowing animations to work as they normally would. This command does not require OP, or cheats to be enabled.

Hide Players
This feature adds the /surge hideplayers command. When this command is executed, only your player will be shown. This feature also adds the /surge whitelist [add|remove] [username] command which allows you to disable this effect for specific players.

Redstone Toggle Fix
This feature fixes a memory leak in redstone torches. A memory leak is a type of bug, where a program claims some memroy (RAM) for a specific task, but does not release it when said task is complete. The leak fixed by this feature caused information about a world to stay loaded, even when that world was not being used.

Load Time Analysis
This feature will analyse the load time of every mod installed. Once the game has started a file will be created in .minecraft/surge/loadtimes which contains approximate load times of every mod. While this shouldn't be used as undeniable proof that a mod is slow or broken, it can be used to spot mods which are bogging down load times. This feature is disabled by default, as it will slightly slow down load times while analyzing the load times of other mods.

GPU Cloud Geometry
This feature significantly improves the performance of vanilla cloud rendering. Traditionally clouds have been very resource intensive, taking up a decent chunk of the total game render time. This feature greatly reduces that chunk of time, allowing you to play with clouds enabled, without losing performance. This feature also adds a /surge clouds command which allows you to toggle this special rendering off and on. Full credit to Zaggy1024 for this feature.
