Hello everyone. So I thought I'd make another guide on allocating RAM to your minecraft launcher. I know there is already a good guide on allocating more RAM, but I thought I'd make this one for the newer launcher as it is a little more complicated and different from the old one.
First step is to go to Launch Options once you've opened your launcher.
Next, you need to click the JVM arguments switch to make it green.
After that, change the number in the "-Xmx3G" argument to however much you'd like to allocate to minecraft. From my experience, 3-4G works the best!
Finally, click save and start playing. Thanks for reading, hope this helped.
