The Vanilla PBR Texture Pack was created by digitalwaltz. As said on the Texture pack's page, this Texture pack is supposed to be a "no new features" Texture pack and stays true to it's name due to the fact that all the textures only use what Minecraft already had/has with small additions in some cases (e.g.: Tools that have been updated with the Anvil).
The Texture pack does not add any new blocks, mobs or items and sticks to Minecraft with no custom stuff. Despite of this, everything looks like something has changed in Minecraft in terms of Texture quality.
The Texture Pack was created with 32x32 Texture tiles and does not require any Modifications (Optifine is recommended though).
This Texture pack's resolution is only available in one size: 28x28. This Texture pack requires more ram than most Texture packs due to it's unique way of making things look like Minecraft has been updated with HD Textures but only really using old Texture assets as a base for creating new HD looking textures.
Due to it's unique design, this Texture pack works best on slower machines or computers that have less ram/memory. Even so, this Texture pack still looks fantastic and loads pretty fast too
I can't recommend using Optifine with this Texture pack though, since Optifine doesn't support Texture packs that have only 1 Texture resolution.
