Good Computer but unplayable

[Zrolo]

My friend and I wanted to get back into tekkit. I can run tekkit just fine averaging about 50 fps. My friend on the other hand, he cannot. He gets about 4 fps in the MENU screen and can't select to join a server or start a new single player world.

 

Before anyone asks for specs, he has 16gb of ram. while its running it only uses about 30% of his ram and 40% of his cpu. We have already tried allocating more ram in the launcher but that did not effect anything. He has a better computer than me so can anybody tell me why it runs better for me and not him. Any solutions?
