Me and my friend were making a custom modpack, with around 40 mods in, to enhance the vanilla game. Both our PC's have the same specs, but he can run it and I can't. We triple checked our mods list to see if we had the same ones, no problems there, we both dedicated 10GB of RAM, but mine still won't work. I can load a world, or join a world, but my game has 0 fps, and a tinker's book is halfway through entering my inventory. The game however, is still responding. Help?
