Faithful Resource Pack 1.12 and 1.11.2 has been created a long time ago, but today it is still one of the most popular texture pack ever created for Minecraft. This resource pack includes Faithful textures for the Minecraft version, and it works great on snapshots and releases too. It is, in my opinion, the best alternative to the old, traditional default Minecraft textures that we have when no pack is installed. This is basically a double resolution resource pack that stays faithful to the original Minecraft textures.
Faithful 1.12 is made of simple and lightweight textures of a resolution of 32×32 pixels. It won’t use much CPU and will provide a noticeable FPS boost as compared to higher definition resource packs. Textures looks bright and natural, it’s essentially vanilla textures upgraded in HD. What is great is that the Faithful Vanilla Resource Pack is supported by a large amount of mods. Most players like it because it is not like the other resource packs, it’s different. Most other packs are crazy and don’t have the original feel of the game, when this one still has the Minecraft feel, but adds a little “touch” to it. This is perfect for having higher resolution, without changing the color scheme of whatever we build from how it looks with default. Like many others, I’m of the opinion that Minecraft looks best with 32×32 textures and this is a great way to keep that original Minecraft look without having to settle with a 16×16 resolution.
Finally, all I can say is that the Faithul 32×32 Resource Pack is an excellent pack, everything looks great. There is also an higher definition pack called Faithul 64×64 Resource Pack, that will suit all your needs if you want to enjoy better textures. Fortunately, it is very regularly updated to the new versions of Minecraft, and each times new things are added! Globally, the textures are looking the same as the ancient ones, but they will be brighter, sharper and with a far better resolution. Colors are really well chosen. For optimal experience, you might want to run Faithful along with OptiFine and a shaderpack!
