Archived the modpack, I'm working on a way better one now

DETAILS
-Minimum RAM: 2
-Loading Screen time: around 5 minutes
-Ram usage: 700mb-1700mb
-FPS: around 20 and 60

-Total 90 mods (with OptiFine it will be 91)
Generally small mods, do not scare!
-Big mods; Biomes O' Plenty, Immersive Engineering and its add-ons, Railcraft, Quark, Geolosys, Roguelike Dungeons
-Main Mods; Immersive Engineering and Railcraft

Attention
-Use pregenerated chunk world once for a world and do not copy it, otherwise it will copy it and delete other one. You have to use pregenerated chunks on only 1 world
-Immersive Intelligence is a bit buggy and glitch, keep that in mind

Hello, I made this modpack for myself actually. I just saw that I can use it on my 2gb ram pc with almost no troubles. I wanted to share it for anyone who has low-end PC and wants to play a tech mod with hard stuff in it :D

This pack hugely insipired from Sbeev's Industrial Revolution and Real Tech Modpack. Thanks to Bforlemon and Danny for allowing me to make this pack

Brief of such things
This pack is sure hard for early and mid gameplay but that's why you start with iron knife, a canteen with clear water, sleeping bag and field manual! Still you have to find some flint and make yourself flint tools to start with. Probably hardest one is finding hematite or limonite for iron source but hopefully there is recurrent complex mod which add ground iron ores, use them for sure.

There are dungeons and ruins all over the place too but wait! Your health only regens when you sleep (2 hearths) You have to get some advancements first. Also beware from blood moons (%1 chance) it will spawn tons of zombies and those zombies can find you from your movements, blood stains or even from your sounds. You might need to live under a rock for several days maybe...

Seasons, your heat, water and low food is a struggle in this pack too. Pam's harvestcraft gardens don't drop tons of food now and they don't give you much saturations (hunger overhaul). Nether is now actual hell and you need water. You need nutritions otherwise you will get food poison and some more stuff

There isn't much transportation stuff like jetpacks or cars, flying vehicles. You have to use horse carts or trains for long travels

For end game, you dont have any quest books, you can create a factory or you can feel the gameplay of hard adventures
You can kill all the really hard to destroy bosses from dungeons mod (wiki) protect your base area with barbed wires and gun turrets, have automated system, struggle with pollution, explode in caves due gas explosions and more thing you might do...

-You can select "release (low settings)" version fom files for completly changing minecraft settings for 1.12.2 for better fps

-Open you mods folder and find betterfps executable jar file. Open it and test algorithms. Do it for several times and find which one has the lowest ms, there is a button under the "test again" button for selecting the new algorithm.

-Now, I hope it is all set to run the game. Open it and select the biome style you want. If you don't want to see new type of biomes in your game use normal. Don't press to play yet! There is a button for pregenerating chunk, which is awesome for you to reduce a good amount of stuttering in game while it was creating new chunks.

Select the radius you want, I did it 100 and it took me soo long. You can do it 50 or 75. Don't forget to change terrain gen to full gen at those settings too.

Start the pregenerating but you will see there is a bar for RAM usage at top right and also a button named GC. You will have to use it once it comes too close to the edge of RAM bar.

Once the generation complete press "add post" for last. Don't forget to watch your RAM bar.

-Finally! After a long time it finished... Join your world and play it. You might be carefull entering nether or end if you didn't pregenerate those. I also recommend opening cheats on before creating the world if anything bad happens and also you should close every other tab except minecraft for better performance. You can change minecraft's priotry from task manager...

Have Fun..
