If you want to allocate more RAM you do this :
- Open the launcher
- After logging in, go to the top left & look for Installations
- Click the + New button
- Give it a name, icon & choose your version
- Below those fields on the left choose More Options
- In JVM Arguments change the -Xmx2G to whatever value you need and/or want
For example -Xmx6G ; now there are 6GB's allocated.
Don't go over 8GB, generally anything over that will be too much depending on your system of course.
A good middle-ground is 6GB.
Copy this into JVM arguments for a quick fix
-Xmx6G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32MNow you have 6GB allocated, wasn't that hard after all was it?
I prefer the old.. old launcher, because it creates a nostalgic feeling.
But I have to be objective here and say, this one is much better & more user friendly =)
Hopefully this helped; noticed Xeria also posted this .. but hey doesn't hurt to have it twice lol
