Glowing blocky guns and tools
Blocks that just disappear
Framerate issues
Extra memory usage (no longer run on grandmas rig)
Fog which cuts off too quickly, making things look really jaggy in the distance
Honestly, the fuzzy blocks and soft fog rendering is one of the main things that makes this game feel unique from other block games. The drunken camera was simply a programming limitation that was fixed, but OpenGL is an entirely different client that isn't needed and doesn't fix any issues! In fact, it MAKES many NEW issues! Not to mention the server list looks like something out of the mid-90's, and we don't need animated "Ace Of Spades" logo wiggling around all over the place.
