That is VoxelMap.
Indeed it is the same thing, but i just have the Zans minimap, without the liteloader and other voxel mods, and i dont notice any drop in fps (no difference from reis to zans,i do notice a difference without the other voxel stuff) I still get around 80-120 fps
Voxel mod has those config options. You can turn off mobs on the radar and disable cave mode.I like aspects of both. I hate the way mobs are rendered on Voxel Minimap as i find it too intrusive. It's cave mod is MUCH better than Rei's though. but Rei's wins with the non-intrusive Waypoints that are visible regardless of distance. Voxel's Zoom and level of detail are better, as well as full screen, but i like Rei's color scheme better.
Lack of a config option for Voxel in order to turn cave mode and mob detection is bad, though... If i could i'd combine both into something better.
