Hi there! I love watching the Attack of the B Team videos on YouTube, so I decided to play, and it is way to laggy. So I took out a few mods, and still the same thing. What mods can I take out that are making it so laggy? I want to keep -Tinkers -Biomes -Natura -Advanced Genetics -Morph -Open Blocks -Random Things -Better storage -Mine factory Reloaded -Project Red -NEI -Tropicraft -Thermal Expansion. I would just leave these and a few others that I would like to have, but i keep doing something wrong I guess becuase I can never get passed the Mojang screen without it saying there is an issue If anyone has any clue on this problem for me that would be great.
