⚡️Optimization Maximized

This Modpack is a extra-large optimization modpack and it combines every single mod that optimizes your gameplay together. Optimization Maximized focuses only on optimization and is NOT lightweight. ( with some very basic QOL mods)

Warning!

This Modpack is still in early development. You may not get the same amount of performance as the example shown. Different devices may result with different fps count.

Our Aim:

• To increase FPS and stability
• To help with networking issues
• To ensure Maximum Performance

Recommended JVM Arguments JVM Arguments can sometimes boost performance by a lot. Here are some JVM Arguments for this Modpack. Remember to use according to your memory amount.

If your amount of memory is not listed here you have two choices.

1. Make one yourself
2. Use a reliable AI Assistance (e.g. ChatGPT)

These JVM Arguments are generated by ChatGPT as well. If you have any suggestions or errors you want to call out, join my discord server to tell me.
