When using the Thaumcraft Thaumometer, you can notice FPS drops, especially whilst scanning. When also using mods that add many aspects such as GregTech, this drop can become even more pronounced, to the point where the game is struggling to run whilst holding a Thaumometer. This mod alleviates these issues to provide a smooth scanning experience.
Currently no known incompatibilities, but there is the potential for them. Any issues found will be fixed, happy scanning :)
