Eldpack Texture Pack for 1.12/1.11.2 was designed to offer a massive game experience while coming with a resolution, as low as possible. The 1.12 Eldpack Texture Pack comes with awesome 16x16 Textures. Originally it was created by "eld", but later updated by Jman37X. If you don't have a fast computer you definitely should give Eldpack a try! Basically it's one of the best 16x Texture Packs out there. For more FPS you can still use it with Optifine HD.
