Got bored and decided to make this d:
Minecraft is a pretty badly optimized game, especially on lower end or older machines. Thank God it has an active modding community (:
These steps are for 1.16.5, if you play an older version they may or may not work for you, YMMV
Device I made and tested this on is a Surface Go 2 with an m3-8100Y (Fanless dual core) and 8GB RAM.
Before: 0 fps lmao
After: 100 fps
Step 1 - Install Fabric Loader from here and let it create a new profile in your Minecraft launcher
- These mods will NOT work with Forge. Don't get confused and complain when you add these mods to a Forge profile and it doesn't work.
Step 2 - Take that new profile and give it it's own folder like so
Step 3 - Launch the game with that profile once, so that it generates all the files and folders and what not, but close the game after because it doesn't need to stay open
Step 4 (The fun part!) - Install these mods!
Fabric API - Doesn't do much on it's own but is a dependency for multiple mods on this list
Sodium - Rendering engine replacement, known for boosting performance a lot and having way better gains than Optifine (though it is lacking in features, which is where...)
Sodium Extra - Mod that adds onto Sodium and lets you fine-tune certain aspects of the game like particles and animations
Lithium - An optimization mod
Starlight - A lighting engine replacement that improves performance over the vanilla engine, and notable other lighting engine mods like Phosphor
Hydrogen - Reduces RAM usage
Cull Leaves - Works like Smart Leaves in Optifine, basically stops the inside of leaf blocks from rendering and improves FPS
Dynamic FPS - Hard-locks your game at 1 FPS when the game isn't focused, reduces system resources if you leave the game in the background to AFK
Better Beds - Changes how beds are rendered, increases FPS
LazyDFU and Smooth Boot - These mods reduce the games start up time drastically
Optifine Equivalent Mods - Since you can't use Optifine with this setup, here are some mods that bring over its best features
If you want the full list of mods that add what Optifine adds to the game, check out this list
LambdaBetterGrass - Better Grass
LambDynamicLights - Dynamic Lighting
Ok Zoomer - Zoom
Dark Loading Screen - Self explanatory
Mod Menu - Doesn't improve performance but helps you manage mods and their configs
Fade In Chunks - Doesn't help performance per-se but it makes the game feel smoother by replacing the jarring, non existent chunk loading animation with a nice fade-in
Minecraft ships, by default, with a pretty anemic version of Java. Using newer versions and a different GC may help increase performance, YMMV.
Step 1 - Install the Azul Zulu JRE for your OS (The version I found works best is Java 15) here
- Keep in mind, for versions older than and including 1.12.2 Java 15 will probably cause a crash. For these versions, I'd recommend using the Java 8 JDK from Azul instead
Step 2 - Change the JVM Minecraft uses by editing your instance (Can't explain this one too well so here's a video)
Step 3 (Optional) - Change the Garbage Collector Java uses by changing your JVM arguments. Edit your instance, completely clear your JVM arguments and paste the following: -XX:+UnlockExperimentalVMOptions -XX:+UseZGC
- This WILL cause a crash if you aren't using Java 15!
- This may improve performance for some, may worsen it for others. Just guess and check and see what works for you.
