Mythical Realms

Mythical Realms was originally created for a small group of people to play for fun but many others can play it as well. It has tons of mods from Twilight Forest to Tech mods and even Magic mods. You can either play on a server with it, or play with it in singleplayer. There is so much for you to do, so have fun. Make sure you have enough allocated memory and correct Arguments or else it will be super laggy.

Arguments: -Xms4G -Xmx4G -Xmn128m -XX:+UseG1GC -XX:+AlwaysPreTouch -XX:+UnlockExperimentalVMOptions -XX:MaxGCPauseMillis=100 -XX:+DisableExplicitGC -XX:TargetSurvivorRatio=90 -XX:G1NewSizePercent=50 -XX:G1MaxNewSizePercent=80 -XX:InitiatingHeapOccupancyPercent=10 -XX:G1MixedGCLiveThresholdPercent=50

The "Xms" and "Xmx" argument numbers should be changed according to how much RAM is installed on the computer.

64-bit Operating System:
* 2GB RAM = -Xms1G -Xmx1G

* 4GB RAM = -Xms2G -Xmx2G

* 6GB RAM = -Xms3G -Xmx3G

* 8GB RAM = -Xms4G -Xmx4G

* 12GB RAM = -Xms6G -Xmx6G

*16GB RAM = -Xms8G -Xmx8G

32-bit Operating System: 

2GB = 1G

4GB = 2G

6GB = 3G

8GB - 16GB = 4G

Make sure to put Optifine into the mods folder after downloading so it doesn't lag a poop ton
