HelloImAndy

I don't know whats happening, but whenever I enter into a game either on my own computer or over Hamachi, the entire world is invisible and extremely slow. I have tried to restart my computer, uninstall the mod pack and reinstall, but to no avail, its not working. I also tried turning all graphics options down all the way and then loading in again, but that didn't work either. Please help!!! Picture should be attached of what I'm seeing. Also, all skins are invisible in loading (pic attached) which might be why, not sure though.
