Description
Discord 
You are XC-443, an ancient human which has been cryogenically preserved by entities unknown to you.
The previous 442 cryo-preservation test subjects all died shortly after being thawed.
Your body is still frozen, but your mind is fully awake.
The unknown entity, which goes by Atlas, wants you to perform a series of simulated tests before they dare to fully revive you.
You'll go along for now, even if you feel something is not right.
What is Cryogenic Simulation?
Cryogenic Simulation is a progression pack with a focus on automation.
The Patchouli guidebook will guide you through the journey.
There is no Nether or The End. The entire progression is meticulously handcrafted to be a unique experience.
The estimated time to complete the pack is 75-125 hours. Depending on how much you focus on progression, and how experienced you are with modded.
The pack progresses relatively quickly to having access to AE2 and automation tools, and that point it slows down a little bit so you have to start focus on said automations.
Design philosophies
- Since the focus is on automation. There is limited combat requirements to complete the pack. The majority is contained in a single pack stage called the "Combat Simulation".
The first dimension only have monsters in the caves, aboveground you are free to build your base in peace. You also retain all your items on death. - Worldgeneration is precise and clean. Walking around a plains biome in the first dimension will feel like a vanilla plains biome. And you wont come back from a exploration trip with 30 different ores or fauna.
- AE2 has a low barrier of entry since its the core of automation. In likeness of games like Shapez 2 or Modulus, where the automation costs nothing or very little.
- The pack avoids poison pill recipes and focuses on interesting mod interactions instead.
Performance
The pack only has 142 mods, and has most of the best-practice performance mods from the 1.12.2 era added in the pack.
Recommended ram: You can probably get away with 4GB of RAM. But ideally on 1.12.2 you should try to go for 6-8GB allocated.
Java Flags
Use aikars flags. JVM Tuning: Optimized G1GC for Minecraft - Aikar's Thoughts
On 1.12.2 (java 8) flags still matter a lot to prevent major lagspikes from garbage collection.
-Xms8G -Xmx8G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=https://mcflags.emc.gs -Daikars.new.flags=true
