I need helping increasing the amount of RAM allocated to technic. I have a 64-bit java, and the launcher only goes up to 1GB of memory. I can play a pack for about 10 minutes before the lag spikes and I crash. I tried increasing the PermGen size, and reinstalling the launcher. I have the same computer as my brother, and his goes up to 5GB, without any error within his game-play. No one seems to have a youtube video about changing the current launchers memory. If anyone can help me out, that would be greatly appreciated.
