Currently, I am having problems allocating more RAM to minecraft. I have 16Gb and I atleast want 2 Gb to minecraft. I usually run 32 render distance and my ram allocating runs out and I have huge lag spikes that don't go away.
This is my current JVM Arguments:
-Xmx1G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M

Thanks!

Change Xmx to 2G.

Here's a picture.

It still haz 499Mb allocated, not 2G.

Do you have JVM Arguments checked off?

Nope. I have no idea why it isn't working.
