Game Performance¶
Game Settings¶
If your game is struggling, try:
- Turning down Render Distance
- Look into JVM args (see next section)
- Giving it some more RAM——but not so much GC pauses noticeably lengthen.
Java and the JVM¶
Which Java to Use?¶
Adoptium is nice; really, any OpenJDK build provider should be fine.
-
Adoptium Java 21: for MC 1.20.5 or later, and Craftoria and All of Fabric 7.
-
Adoptium Java 17: for MC 1.17–1.20.4; and All of Fabric 5, 6, and 7.
Java and Minecraft versions, and our Modpacks¶
| AOE Pack | Minecraft version | Java version (tied to MC version) |
|---|---|---|
| Craftoria | 1.21 | Java21 |
| AOF 7 | 1.20 | Java17 (runs better on Java21) |
| AOF 6 | 1.19 | Java17 |
| AOF 5 | 1.18 | Java17 |
| AOF 4 | 1.17 | Java17 |
| AOF 3 | 1.16 | Java8 |
Java Args¶
For Clients¶
Around 6–8GB should work well for any AOE modpacks.
| AOE Mod Pack | Java Args for Client |
|---|---|
| Craftoria | -XX:+UseZGC -XX:+ZGenerational |
| AOF 7 | -XX:+UseZGC -XX:+ZGenerational, with Java21 |
For Servers¶
On a server GC through-put may be more valuable than latency—which the default G1GC garbage-collector will deliver.
