 **It is highly recommended to have all optimizations enabled, as they greatly reduce network load, and all optimizations
 are configurable on a per-Active Model basis.**
 
+### Bundle Everything
+
+Should all packets send by Model Engine be bundled and sent in one go.  
+This optimization utilize the new Bundle packet introduced in 1.19.4. **In theory**, this will massively reduce overhead
+caused by sending packets separately.
+
+### Bundle Size
+
+Maximum amount of packets allowed in a bundle.  
+Since packets wrapped in a bundle are forced to be processed in the same tick, too many packets in a bundle may cause
+the client to lag.  
+Minecraft by default only allow up to 4096 packets in a single bundle. 
+
 ### Cull Interval
 
 The culling interval of an Active Model. Smaller value means more frequent detection but more calculations.
