To actually improve FPS a resource pack has to use fewer resources than the default. Most "PvP" packs do the exact opposite, going high-res and then claiming that somehow they improve FPS, which just isn't true.
So just search for any 4x or 8x pack and it'll do what you want it to do. There aren't many out there, but there are enough and they deserve some love. They're also pretty easy to find because of how few exist.
Anyone know any good 1.8.9 FPS boosting texture packs? This is mainly for PvP so I dont really care if it looks nice or not.
