[Epilepsy Warning]: If you become a Matter Overdrive Android (e.g. eat red pill), and you take any damage, the glitch effect may trigger epilepsy. Do not become one if susceptible

Read Before Installing

1. As of August 4, 2026, Matter Overdrive Refitted’s Curseforge page states “[n]ote that this fork is assisted by AI!”

1. This modpack will use it since it’s made by the CleanroomMC team, and the intention seems to be to bugfix and optimize the mod and not steal it

2. However, if I find that this mod is using AI inappropriately, it will be replaced with Matter Overdrive: Community Edition or any other up to date version of Matter Overdrive that doesn’t use AI

2. Updating Cleanroom or Mods by yourself (not from official modpack updates) may cause issues. Before updating anything:

   1. You can exit out of Cleanroom Relauncher to do this 

   2. FTB backups is also installed to backup your worlds  

1. Backup (create a copy of) your modpack and/or world(s)

2. Enable Pack Companion and Crash Assistant before launching to confirm there are no issues

3. If needed, revert to a previous version of Cleanroom and/or Cleanroom Relauncher

3. When the Cleanroom Relauncher window appears, click “Relaunch now”. It will install Cleanroom

   1. Backup (create a copy of) your modpack and/or world(s) before updating

   2. You can exit out of Cleanroom Relauncher to do this 

   3. If needed, revert to a previous version of Cleanroom and/or Cleanroom Relauncher

1. If this is your first time installing Cleanroom, give it a minute to install after clicking “Relaunch now”

2. Cleanroom is safe and improves Minecraft’s performance (e.g. uses Java 25 instead of Java 8, which makes the game buttery smooth)

3. Cleanroom is generally stable, but sometimes updating causes bugs. Here are some tips if you run into this issue

4. Do not use /time set in-game

1. It breaks Millenaire

5. Shaders are incompatible and will not be supported until there is a good mod for them

1. No Iris Shaders/Oculus Port to 1.12.2

2. OptiFine causes way too many bugs and I’m not allowed to include it anyways

6. Keep Pack Companion off (unless you're manually updating mods) 

1. It does not improve nor diminish gameplay nor performance

2. I’ve kept in disabled for when I need to update mods or add new ones. It helps with verifying updated/added mods don’t cause issues

7. I won’t be actively bug fixing this modpack

1. I don’t have a lot of free time, so don’t expect regular bug fixes

2. I have tried my best to remove bugs I noticed during development

Potential Issues

1. Updating Cleanroom or Mods by yourself (not from official modpack updates) may cause issues. Before updating anything:

   1. You can exit out of Cleanroom Relauncher to do this 

   2. FTB backups is also installed to backup your worlds  

1. Backup (create a copy of) your modpack and/or world(s)

2. Enable Pack Companion and Crash Assistant before launching to confirm there are no issues

3. If needed, revert to a previous version of Cleanroom and/or Cleanroom Relauncher

2. Do not use /time set in-game

1. It breaks Millenaire

3. Celeritas: Use -dev files, not -dev-dev files

1. Game will crash

4. VintageFix’s mixin.bugfix.tab_complete_ddos is disabled by default

1. Crashes game when opening chat as of Cleanroom 0.6.10-alpha

5. Start-up Borderless/Fullscreen may not be maximized properly

1. Hit F11 twice to fix

6. Keep Modernity Connected Glass as the topmost resource pack 

1. It won’t work if not 

7. To equip/unequip saddles/horse armour consistently, hold shift on an empty inventory slot before clicking on saddles/horse armour

Story

For centuries, the Empire reigned supreme as the dominant nation state in the world. But recently, that began to change. Their historic rivals like the Noggs, Norska, and Sarkonids have been slowly catching up, the Walker Kingdom defeated and forced the Imperials to withdraw from the snowy regions, and the mysterious Walking Metal continue to spy on the Imperials, despite no one knowing who they are, where they came from, and what their goals are. 

Domestically, the situation isn’t much better. Pirates and Barbarians are active more than ever, tensions between the Imperials and the local Tribes continue to brew, the growing Cultist Movement gains momentum, and echoes of secession can be heard all across the Empire, though never in plain sight, but certainly not in secret either.

The Imperials knew something needed to change. To quell Reveran secessionism, they created the Province of Revero with you as its Magistrate. Your job is to build up the Province and make it a modern power that will be used as a model to modernize the rest of the Empire. For this, you’ll need to learn key areas, such as city planning, combat, magic, this new radical idea of “industrialization”, and even foreign arts like the Cultists’ magic or the Walking Metal’s technology.

Given Revero’s autonomy, it’s up to you to decide what the Province’s future will look like. Does Revero remain part of the Empire or declare independence? The choice is yours.

5. Storage: SSD (haven’t test HDD)

Recommended Specs Settings

   1. I believe it shouldn’t lag your game, but it’s hard for me to tell since my i5-9300H kept thermal throttling during testing (see limitations section)

2. Modpack RAM: 6 GB (6144 MB)

How I determined recommended specs

Test conditions

1. Cleanroom version (replaces Forge version): 0.6.10-alpha

1. 1. 1. Although tested in this version, keep Cleanroom up to date unless you run into a gamebreaking issue

2. World

   1. Seed: 72636176830994657

   2. Coordinates: 368 91 631

      1. Note: AW2 structures do not spawn consistently on different worlds with the same seed at the same coordinates 

   3. Test Structure: The Earls Castle (AW2 castle with lots of imperial soldiers + small town of NPCs outside)

3. Game Conditions

   1. Cheats: ON

   2. Difficulty: Hard

   3. Gamemode: Survival

   4. Weather: Clear (see limitations for why I didn’t test under thunder)

   5. In-game Time: Daytime (for consistent results, though nighttime would be harder on specs)

4. Commands

   1. /gamerule keepInventory true

   2. /gamerule doFiretick true

   3. /spawnpoint (can come back to test starting position if needed)

   4. /effect PressDestroyer minecraft:resistance 100000 255 (don’t die during tests)

   5. /effect PressDestroyer minecraft:saturation 100000 255 (don’t die during tests)

   6. /difficulty hard

   7. /gamemode survival

   8. /time set day 

   9. /flarec sampler start 

5. Computer Conditions

   1. Brave Browser open during testing (4 New Tabs + 1 Google Doc Tab)

   2. In empty Discord server call (w/ voice activity, no push to talk) during testing

   3. MSI afterburner (for fps statistics) open during testing

   4. Prism Launcher open during testing

      1. Homescreen was open

      2. This Modpack’s console window/minecraft log was open

FPS-Frametime Test: Is the game running smooth?

1. Set the game to the recommended specs settings and test conditions above except for following exceptions

1. Modpack RAM: Minimum memory usage (-Xms) and Maximum memory usage (-Xmx) were both set to 6 GB (6144 MB). However, as of Aug 31, 2026, I’m not sure if this really improves performance 

2. Screen Mode: Windowed (not everyone uses Borderless/Fullscreen) 

3. VSync: OFF (not everyone uses VSync)

2. Run around inside the AW2 castle for 5 mins under one of these conditions. Repeat test until all conditions have been tested

1. Neutral AW2 NPCs

2. Hostile AW2 NPCs attacking me

3. Re-run test or determine if changes needed to be made

TPS-MSPT Test: Is the world running well?

1. Run /flarec sampler start under these conditions

1. Hostile AW2 NPCs + 2 Hostile Ice and Fire: RotN Edition Fire Dragons attacking me

2. Re-run test or determine if changes needed to be made

Limitations

1. Haven’t tested this in multiplayer (e.g. LAN UPNP, which turned out to not work for me personally. Others may see it work)

2. AW2 structures do not spawn consistently on different worlds with the same seed at the same coordinates. This makes repeatable testing harder for myself and other independent parties

3. Don’t have a variety of hardware to test, so it has only been tested on

1. Intel i5-9300H

2. NVIDIA GTX 1650 mobile

4. Testing results could’ve been hindered by my i5-9300H downclocking when it thermal throttled. Due to this:

1. FPS-Frametime and TPS-MSPT tests were split into 2 separate tests since /flarec sampler start caused throttling

2. Didn’t test /weather thunder since it consistently caused throttling 

3. Did test realtime dynamic lighting at night, but it was hard to tell if specs could handle it due to throttling
