Now i know that many other people have had this problem as well. I've spent some time trying to figure out what the problem to this is. Most just say it's a problem with not allocating enough RAM. I don't have a problem with that as my computer has 32 Gigs of RAM (I use it for multiple Modeling Programs), but I'm not sure my CPU is capable of handling the texture pack. As i said, I'm not sure, but I'm skeptical that my computer can't handle a 64x64 texture pack. It works fine with just minecraft textures, but whenever i patch it, with numerous types of patches (I'Ve tested multiple modpacks), the game freezes then doesn't load the textures. I even adjusted my NVIDIA graphics in hopes it might help. Nope.
