Now that I have your attention...
Anyone else experimented with the Voxel mods included with the Ultimate pack to see if modifying/removing them has any kind of impact on performance? After about two weeks and hours of googling and experimenting I finally solved all of my Optifine issues by disabling the Voxel mods and installing Rei's Minimap. Rei's hurt performance as well, particularly when loading into the world, but it didn't come with the same overhead, so to speak, that the Voxel kit did. And also, knowing that the ridiculous nyan cat will never again make an appearance on my screen was a welcome bonus.
