Faithful 4×4 Texture Pack 1.20, 1.20.5 → 1.19, 1.19.4
You might think that the Faithful 4×4 texture pack is the normal default pack, but that’s not true. The resolution of 4×4 is significantly lower than the standard 16×16 pixels per block that you know from Minecraft vanilla. While the graphics are significantly more pixelated, a big advantage of this low resolution is that you get much higher FPS.
