Mine Colonies + is a mod pack based around the mine colonies mod. The mod itself is very fun and engaging so please show the creator's support. This has mods I personally love using and make the game a bit better! It also includes every mod you need to run Mine Colonies. Also, Jade 1.20+ is experiencing issues running with Optifine so after Optifine fixes that downloading it can increase your game performance also adding shaders to the game!
Mine Colonies is a Forge mod meaning there aren't too many mods I can add to this for performance, but it did run smoothly on my potato PC so it shouldn't be unplayable!
