While this pack can be used for single-player, it is pre-configured and has been tested specifically for use on the official Cobblemon Ultra server.
🐢 Having Performance Issues or Lag?
While Cobblemon Ultra includes heavy optimization mods like Sodium, Lithium, and FerriteCore, advanced features like Distant Horizons (which allows for massive render distances) can heavily tax lower-spec laptops and older hardware.
If you are experiencing low FPS, stuttering, or game lag, we have a custom low-spec configuration ready for you that disables heavy visual features. Please reach out directly to @Kaividian on our official Discord server for assistance.
