Atomic (Wayland)
Minimal Mods. MAXIMUM Performance. NATIVE Wayland.
THIS IS THE WAYLAND BUILD!
-
If you're on X11 just use the main build and if you don't know, just open your terminal and execute the command "echo $XDG_SESSION_TYPE" and if it returns X11 please download the main build.
How to setup Atomic
- Download Atomic (the modpack)
- Download Prism Launcher
- Import the .mrpack into Prism
- Click "Edit" and go to "Settings" on the Atomic instance.
- Click "Tweaks" tab, and enable Native Libraries - Use system installation of GLFW
- You have to use your Wayland native system GLFW build otherwise Minecraft will crash
- If it's not filled make sure you have a Wayland native GLFW build
- Common GLFW directory: /usr/lib/libglfw.so
- Apply these JVM arguments:
-Xms2G -Xmx4G -XX:MaxMetaspaceSize=268M -XX:+UseG1GC -XX:MaxGCPauseMillis=100 -XX:InitiatingHeapOccupancyPercent=40 -XX:+ParallelRefProcEnabled -XX:+DisableExplicitGC
- If you use a 64-bit Linux use these instead:
- (ATOMIC RECOMMENDS AZUL ZULU JAVA 17!)
-XX:+UseZGC -XX:+DisableExplicitGC -Xms3G -Xmx4G -XX:MaxMetaspaceSize=276M
- Prism will complain about the RAM being set via JVM arguments to just remove these:
-Xms2G -Xmx4G -XX:MaxMetaspaceSize=268M
- And set the RAM yourself

How I test them
World fully loaded, same visuals (blocks/entities/clouds), VSync off, FPS uncapped, F3 enabled + rapid toggle, defaults for each pack, JVM only tuned where provided.
NOTE: These are just comparisons all of these modpacks are great and the count is just for reference.
FAQ (5 questions)
Why 1.17.1?
- Newer Minecraft versions can introduce more worldgen complexity and rendering overhead, which can drastically reduce performance on low-end hardware.
Why are you strict about mods?
- Every additional mod increases CPU, memory, and loading overhead. I only include mods that improve performance or stability.
Why Fabric?
- Fabric is a lightweight, simple, and fast mod-loader and works really well for Atomic.
Will you add QoL mo-
- No. Atomic is built to be optimized and lightweight not include redundant QoL or bloat mods but it is still highly recommended to replace OptiFine with Atomic.
Will you upload it to CurseForge?
- No, the official modpack will be Modrinth only.
Atomic's purpose
Atomic's purpose is to be a strict optimization pack designed to run on weaker systems. Atomic includes only mods that improve performance or stability and can only have 1 mod to optimize a certain part of the game
