Q: Does this render using my GPU?

A: Yes.

Q: Is there multiplayer support?

A: Yes

client side only:
If you only have DH installed on your client LODs will be saved between sessions, although you have to explore the world to load them.

Server and Client:
If DH is installed on the server and client, LODs will automatically be sent to each connected user that has DH installed and has Distant Generation Enabled set to true, disabling distant generation on the server will prevent LODs from being sent to the users.

A: Try each of the following steps:

Use a concurrent garbage collector like ZGC for Java 21+ or Shenandoah for Java 8-17
- This can be done via your JVM arguments (args)
Increase Minecraft's allocated RAM
- For CPUs with 4-8 cores: try allocating 6-8 GB
- For CPUs with 10+ cores: try allocating 12-16 GB
Lower DH's CPU load in the DH config menu
Disabling DH's "Distant Generation" in the DH config menu
