You are playing on a laptop and it maybe not powerful enough to run the pack correctly. Post a console log so I can to take a look.


Edit: Have you tried the curse launcher?

You could also try fastcraft or optifine as it may help. While optifine may help it can also cause issues. So use it an your own risk.

You can also try MultiMC to launch the official FTB only packs.

Probably different java settings in the launcher. Without logs there is nothing we can do.

Which other launcher are you using that runs smoothly? Have you correctly configured the launcher to use the amount of RAM you want it to?
