When you have sliced a file also the GUI becomes extremely slow just scrolling the menus, i.e., it takes 2-3 seconds before the menus move. It is the size of the sliced result (gcode) that decides if it is slow - not the size of the STL file. If I slice a 500 k or 25 MB STL file does not matter - it is the volume of the result, that matters.\r\nIf I load a model and have turned of auto-slicing everything responds quickly. As soon as I have sliced a big item everything including the menu starts to crawl. \r\n\r\nThere is an issue somewhere that delays all UI interaction when the sliced result is big and since it is also the menu with auto-slicing turned off it is probably not related to the actual slicing or graphics. [http://gcode.ws/](url) can visualize and rotate the resulting Gcode in real time on the same computer and so can Simplify3D."}}
