SB Pack is a unique texturepack. It's main purpose is to speed of minecraft, while still giving a bright, and plesant look. The picture above will give you a pretty good idea of what I mean. SB Pack is optifine compatible. If you use optifine, with SB Pack, the FPS will be MUCH better. I would definately suggest this for laggy servers, players and owners. If your players complain about lag on your server, make this the resource pack, it's free, and no extra RAM is required!
