Hello players of Pixelmon Harmony, there used to be a guide on how to allocate more RAM for the technic launcher but I couldn't find it anywhere. So, I am making a new one for you guys to use in case you don't know how to allocate more RAM or have forgotten.
Locate Launcher Options at the top right of the launcher.
Once you have located it, please go ahead and click it.
Once you have entered the launcher options, now locate Java Settings.
After locating the java settings, click to enter the tab.
Once you have entered the java settings tab locate the Memory section and click the drop down menu. The default ram allocated is 2gb, but for a more lag free experience I highly recommend using 3-4gb and there is no reason to go over.
*Disclaimer* I recommend you not go to 3-4 gb if your computer only has 4gb of Ram in it as instead of helping it can cause more issues.
