This mod requires the Compact Machines mod, but it hasn't been published into modrinth, so I cannot register it as a dependency.

FPSCompress

A NeoForge 1.21.11 Minecraft mod that enables factory compression through intelligent rate caching. Run your factories without chunk loading overhead by caching production rates and simulating them mathematically.

What Does It Do?

FPSCompress allows you to build factories inside Compact Machines rooms and run them virtually without keeping those chunks loaded. The mod measures your factory's actual production rates during a calibration period, then uses fractional math to simulate production while the factory dimension stays unloaded.

The Result: Massive server performance gains for factory-heavy builds.

Core Concept: PreFabs

PreFabs (Prefabricated Factories) are upgraded Compact Machine blocks that act as cross-dimensional conduits between the Overworld and your factory dimension.

How It Works

1. Build your factory inside a Compact Machines room
2. Place Importer/Exporter blocks inside the CM room (input/output gates)
3. Upgrade the CM block with a TPS Upgrade item → becomes a PreFab
4. Configure PreFab faces to link to specific Importers/Exporters
5. Connect chests/hoppers to PreFab faces in the Overworld
6. Start Simulation mode to measure production rates (CM chunks loaded)
7. Enter Cached mode to run factory virtually (CM chunks unloaded)

The Three-Block System

• PreFab Block (Overworld) - Routes resources, controls state machine, no internal storage
• Importer Block (CM dimension) - Input gate where resources enter factory
• Exporter Block (CM dimension) - Output gate where resources exit factory

State Machine

BUILDING → Player configures faces, places Importers/Exporters SIMULATING → PreFab measures actual production rates (CM chunks LOADED) CACHED → PreFab simulates production mathematically (CM chunks UNLOADED ← Performance!) HALTED → Input starved or output blocked (CM stays unloaded, player fixes Overworld side)

Example Setup

Overworld: [Coal Chest] → [PreFab NORTH face: PULL ITEMS → Importer #1] CM Dimension (while SIMULATING): [Importer #1] → [Furnace] → [Exporter #1] (PreFab measures: 0.213 iron ingots/tick) Overworld: [PreFab SOUTH face: PUSH ITEMS ← Exporter #1] → [Iron Chest] During CACHED mode: - CM dimension chunks unload - PreFab accumulates fractional production (0.213/tick) - Every ~5 ticks, PreFab pushes 1 iron ingot to output chest - No chunk loading = Better server TPS!

Current Status

⚠️ This mod is in active development.

Core systems implemented:

• ✅ Face configuration system with GUI
